I have used these brakes on 3 bikes, some more than others, the one That the threads for the Torx screws failed, was the one I used on my main bike.
The brake lever body/Master cylinder flex when braking harder than 50%,which is why the plastic lid & the separator & the Master piston unit to bend or get damaged, and cause leaks, so the lever will be soaked in oil, and oil will spit out through the middle where the plastic lid is.I compared the flexing in the levers on m396&m615 and there is significantly more flex in the m615, if you press the lever blade half way you wont see flex on the m396,but on the m615 you will.
Leaking caused by plastic cover bending upwards, and front and the back is also being pushed upwards but sideways too, causing a leak.
temperature changes, will cause this, a minor hit can cause this. the design is clearly flawed.
I had to replace one master cylinder due to failed threads, and I had the leaking issues with the new one too,but with a set of pliers it was fixed, by pressing the cover into the master cylinder until it was straight/flat against the master cylinder,but this is pointless to do, you are better off buying a mechanical brake or a proper hydraulic brake.
Impossible so far to get placement seals/grommets/diaphragms, or just the master cylinder separately.
I don’t know what caused the threads to fail, it was certainly not over torquing the screws,I don’t know if its caused by fluid pushing the parts and girding the threads apart until they are so polished that they cant hold the cover, maybe I don’t know, I certainly was not a crash that caused it,because I never crashed with this particular brake.
Hinged clamp,no need to remove grips & shifter.
the levers are easy to bend back if you bent them,which I have done on 2 bikes so far.
good braking power,at least if you use Metal pads, ( if its wet or ride a lot)
it’s not too expensive
it’s not too heavy
no need to take off grips to take off the brake, because of the swing arm clamping mechanism.
The Brake Lever will bend if you crash into a tree(before I upgraded the handle bars i was used to ride on the fuel ex 7 with 720 bars),at low-speed,don’t just let the bike fall on the ground,it can bend the brake lever.
You can of course bend it back with proper tools and technique.
M615 Piston seals:
IUY 21.1 25 3.19 78 NOK
The Both brakes are too fragile.
Because the brake lever body/master cylinder is way too flexible and that there is a palstic lid,instead of metal lid,which causes the brake to leak.
I have seen a lot of reviews claiming these brakes are a good value at a low price point.
I agree with the braking power for the money is there, but not the reliability, these brakes are too fragile.
same goes for the other brakes with the similar design, for example, M396, M395,but at least it’s possible to get seals for M396, M395.

POC is well known for their protection product.
I have several POC products now and I recommend checking them out.
This glove is my favorite glove so far.
they cost the same as the giro remedy X gloves and are way better when it comes to comfort & Poc offers protection padding but Giro does not.
because these gloves were actually bit too big(size large) I changed to 2016 Resistance strong gloves(size medium),the palm on some of the gloves worn out, I think this is caused by the material used & the venting holes in them, so far the Index Dh has been holding up OK,but I guess over long period of time they will eventually wear too.
If I use the 42T cog on the cassette the chain will fall off when back-pedalling, but when I shift up to 37T cog the chain stays in place no matter how hard I pack pedal.
On Hope Pro 4 freehub:
the Pro 4 free hub, is 11 speed compatible, which means it’s wider, and comes with a spacer,and with 11speed cassette, the cassette is closer to the frame/more outwards to the right, which gives a better chain line, so the backpedalling issues is gone,Unless you backpedal at unrealistic speed,then it will fall off,but I have done 180 U turns in 1stgear(42T) and the chain never fell off.
So if your rear hub is compatible with a wider freehub,you should get one.
Huge noise reduction when riding:
The first thing I noticed after I upgraded to 1×11 is that all the slapping ,banging and scraping noises are gone from my bike.
The narrow wide chain-ring will make more sound than the triple chain-ring, but when ring in rough terrain or jumping, the noise is a lot less than a conventional triple ring set-up would make.
There is big difference in the force needed to press to press the small trigger(up shift),but I got used to it after days ,and it did not feel as hard to press, and I like the shifter feel,I get less accidental shifts this way.
The change in gear is instant like promised.
The possibility to shift by bending you finger and do a finger kick motion,which you can’t do with Sram shifters.
(like this(https://youtu.be/7HvJma35fZA) to push the lever/trigger is gone, as the Shimano Deore 10 Spd had.But for me this is a acceptable compromise.
But there will be no accidental shifts
There is huge difference in the force required to push the triggers between SL-M610 & M8000 , so if you plan to upgrade a kids bike you might want to let the kid try it out first,but for the youngest I recommend getting SL-M610 or something similar.
you can shift down 4 gears
The I-Spec B shifter will have rotational play,because of the pin system, it’s not avoidable.
The screw came with a lot of Blue thread-locker,so needed to try few times until I finally got it tight without loose shifter.
But the adjustment screws did not,so you have to buy thread locker for them, I used Loctite 243.
The rear Derailleur:
A lot stiffer Clutch system, which is good.
Very smooth,fast shifting movement.
Esy to service, as long as you got magnetic bowl, and are careful with the round seal fo the spring assambly.
Race Face Narrow wide:
The chain will not fall off no matter how hard I ride, if it falls off you must be crashing really hard.
There is some drag when pedalling but this is not noticeable when riding, the chain still wants to be on the ring for about a half of a second, but this is impossible to avoid with Narrow Wide.
set up used in test: 2010 trek 6300 1 x10 36-11T cassette Shimano SLX Shadow Plus, with 36T Race Face Narrow Wide chain ring.The chain dropped when it was in 24 Tooth cog, but when I tried in 21 cog it stayed on. Even on stairs that were not that steep probably 40 degrees,the chain fell off.
Pros of 1×11:
You get all the gears you need if you just select the right chairing for you.
a lot quieter drive train
dropping the chain is rare unless you ride in low gears down steep stairs.
No front chain rigns to deal with
easier to clean the drive train,less dirt & mud on the drive train
if you want to sue a chain guide, you can use a single ring chain guide which will be more secure,and look better
if you use a wide range cassette with a 9T cog you can get the a pretty high gear as you could with triple rings,but with 11-42 with 36T cassette I get a pretty good range,but once I get on the 1km flat straights I will run out of gears
Cons of 1×11: There are no real cons riding 1×11 it will havefaster wearing cassette and chain of course,but that’s not a reason to not upgrade. the 37 and 42 cogs are the fastest wearing cogs, because of the bigger chain angle.
the cassette & chainring wore out at the end of the season like it did with 10×3, maybe few weeks sooner wear. I don’t have to shift as often and skip so many gear so often,so I get less side to side wear on the chain,by using 1×11,so the chain growth will be less.
If i changed the chain,a lot earlier, the cassette and ring would have lasted longer,but I had no spare chains,but I have a stock of chains now.
The Rear derailleur cage will have visible wear, with 1x setup,because of the chain line the chain will hit the plates,but its not a big deal.
I absolutely recommend Both the Xt m8000 drivetrain and the Race Face Narrow Wide single chaining.
I need a fork as fast as possible, this fork was the best I could get at the time straight away.the 2012 XCM v3 I had on the Trek 3900 worn out, so I had the local shop swap the 2010 Rockshox Tora SL fork over from the 6300 to the 3900, and get the Corsa on the 6300.The fork plus lighter handlebar & stem (race face turbine) made the front a lot lighter.the flex is about the same as on the Rock Shox Rora SL, bu the suitability is much better.
The fork was making less noise, the knocking sound was almost gone or maybe gone, itsI had no issues riding in -6 degrees Celsius.I don’t know why the fork get silenced in below freezing, and the knocking is back with above freezing.
If you crash a lot, and need a durable jersey, POC Flow is a good choice.
if you want soft and super comfortable jersey i would go for the Trail jersey instead, biut for me this is OK.
confortable, the jersey is smoother inside than outside, so it will not be as unconfortable as you might think.
Very Durable,i crashed 2 tiomnmes ( on concrete stairs and on asphalt) with this jersey on and it still looks like new,but i assume if you crash very bad the POC logo might get some scrapes.
no itchy size label
i ordered wrong size but i kept it did not have time to deal with it so i just used it, but one size too small was wearable but not so comfy to put it on, but hopefully i can get some more of these in the right size
Conclusion, if you want durability, the POC flow jersey is a good choice.
they lasted the rest of the season + some more weeks.
With these tyres you actually need to follow the pressure recommendations.
Awful durability, I upgraded to Se team issue tyres,but currently(2016) run Maxxis High Roller 2,they have better grip, and don’t wear out as fast as the XR3 Expert.
the tyre is squirm at lower pressures. So you can’t use lower pressure than 30 psi I’m somewhere between 170 and 180 Kg and I need to keep the pressure at 40 psi,30 psi still makes the a unstable steering.
the grip is not as good as on Maxxis’s 3C Maxx TerraCompound.
the saddle is harder than the Bontrager race saddle on the 2010 trek 6300,saddles is a personal thing,not every one will find every saddle comfortable, this saddle was not the most comfortable one I had.
durability is acceptable, it did not wear out or bend og any screws that fell out, so this is good,i got few holes on the sides from few crashes.
becomes slippery after at least 1 year of use
the black stripes that go on the sides ,top of the saddle wear out after much riding.
I heard the lizard skins are way too hard,since i already got ESI grips and they are much better than rubber grips,I ordered the extra chunky grips too.the chunky feel much better than any cheap rubber grip or lock on grip I ever had.
i need little bit more shock absorption,I can compress the grip so i can feel the handle bar,i will change them out for Extra Chunky’s hopefully they will be better.
But that said they are a big improvement, my hands hurt less,and its more comfortable to ride.
After almost one season the grips began to wear,and became ruff and started to peal off small flakes.
feels great without gloves
good grip,even when wet
10 colour choices,i got green fits my fuel-ex perfectly.
stays in place, does not slide off.
reduces hand numbness – fatigue- arm pump
easy to clean
they can be used in the winter, I have ridden few days with -10 and more, with the grips, with out any issues.
if you crash hard into a tree or something or similar, there is a big chance that they rip.
wear out faster than rubber grips,but for me its definitely worth getting more Esi grips,at least for mountain biking its a must for me.
birds can damage the grips like here,after more than a week there are holes so deep i can see the handle bar.
Putting them on and off:
What you should NOT do:
My method is better than the recommended method by ESI.
DON’T USE A SCREW DRIVER TO PUT THEM ON AND OFF!!! It will damage the grips on thee inside and the grip can rip apart.
Don’t use hair spray, even the bike mechanic tells you to, it will stink, and make the grip slipperier on the inside. no dangerous stuff to breathe that way. and no stinky grips and handlebar.
Don’t use a screwdriver
The best way to put them on or of is to use hot water!!!
I use this method below to fit my silicone grips. Hot tap water method: by doing it the way I do will ensure easy installation of grips. Let turn the use hot side only,to the high pressure,let the sink fill up with hot water keep most of the grip in in the water,to avoid pain don’t dip the while grip with your hands in the water, flip the grip to the other side do the same, the just push it on and and and for final step spin it into place.
good grips no matte if its wet or dry you get one of the most conformable grips on the market,and the price is not bad either.
I was so impressed with these pedals that I ordered more sets so now I got 4 in total.
I run these with all pins, and the grip can’t even compare to normal cheap pedals they are on a whole new level.
I have jumped and landed with the pedal on a end of a stair end and no damage not bend no play . but they are now on my fuel ex and the left crank arm failed and the left pedal fell off, the threads for the pin failed few days later, which is probably caused by loosened pin, and damage to threads was probably done wheel the pedal fell off,I have Used Loctite 243 all of my pedals,the thread locker on the pins are will no do the job properly, So you have to apply some more.
No I did not overnightened them,it as a bike mechanic in the store that switched the pedals from my trek 6300 to the fuel ex.,good they had a spare crank.I have used the pedal with the xt crank arm I got and the pedal did not fall of, so i assume it was just a faulty crank arm that caused this.
After about 2 season of use the metal rings and the locking clips will show sings of wear,and there will be noticeable play and knocking sound.
But straight line provides spare parts,which can be bought directly from their site,or from online shops.
Only one size,for sizes above 44 these pedals will be too narrow,my size is 43-44,and my shoes go over the platform by about 05cm.
Very durable,can take some abuse.
easy to replace pins
easy to service,one of the easiest on the market right now
many colour choices, will match most bikes
Excellent pedals, I absolutely recommend these.
If you want the best gripping concave platform pedals on the market but not spend much cash on light weight pedals go for the defacto pedals!
but they not the lightest pedals with good grip on the market, but if you want to save weight go for the Syntace nine nine titan instead,but the Straightline de facto are much cheaper.
jeg trengte verktøy til å ha med i sekekn når jeg syklet, men når jeg trengte å bruke det så ble jeg jammen skuffet. det er er verdig nedslitt fra fabrikken.ingen av umbrakonøklene passer til noen av umbrakoskruene på mine sykler, de er rettog slett for små.
positivt: ikke noe positivt å skrive
negativt: er som nedslitt verktøy, så du komemr til å slite ut skriene fordi de er altfor slå, jeg har kjøt Lezyne SV 10 verktøy og park tool AWS-10,AWS-9, og torxTWS-2 og de passer helt perfekt.
slark, umbrakoskruene som holder verkøye sammen løsner altfor ofte,
perfect fitting chamois, not too long not too short.
Velcro adjustment staps
Pockets are in awkward place.
the padding/chamois is not damping as Poc’s chamois i presently purchased,it should bit bit bigger both i the front and the rear.
the shorts are too short to be used in the fall/autumn,winter
Hard to open and close side venting zipper.The side venting is in a awkward angle, so the zipper is hard top close and open. The zipper handle is sliding out of my fingers when I try to close or open the vent.
too short venting zipper,should be longer and on the side instead for perfect venting,so you will get bit too hot in the warm summer days. I now use Poc trail vent shorts and they are perfect when it comes to side venting.
chamois short does not fit well ,private parts don’t stay in place, the elastic band should be bit tighter, should not be as big in the rear, the chamois shorts should be cut and stitched differently,when I wear these shorts they are do not fit as i the pictures,I need to have the elastic bad all the way to the waist.
Too short hood and loop straps:but large is is so bit that to make it tight i need to go over the limit on the straps.
the insides of the pockets can get stuck in the zipper if you are not careful.
the the zippers can get stuck on the inside of the pockets if you are not careful.
I have 2 pairs of these shorts one in large and one in medium, on both the stitching in the middle in the crotch area ripped.
27.05.2016 I tried on the the medium shorts,I have not sopped crowing 100% yet, so they no longer fit my hips are a lot wider
I am using POC shorts in size 32,the Craft shorts in large fits, but don’t need the adjustment any more,I am now 36inches in the hips.
the size large Craft shorts are 2cm narrower than the Poc trail vent in size 32.
I can’t recommend these shorts, because the chamois underwear that is included is too small and thin, I prefer Poc’s chamois.
you are better of getting more expensive shorts,i recommend Poc trail vent shorts,instead because got 2 pairs and i am satisfied with them.
