Long term review on 3 bikes: Shimano Deore M615 I-Spec-B brake set- it’s garbage

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.

Cons:

  • 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.
The threads for the Torx screw failed, which is clamping the cover which clamps down the grommet, SO fluid leaked, But I don’t know if it just failed, of if it was due to a crash, but the Torx screw was not damaged. In my opinion these screws are way too small,the design is way too fragile.
  • 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.

Pros.

  • 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 modulation
  • 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.

The I spec B system, is flawed, it’s quite flimsy, the shifter will move if you did not use Threadlocker and torqued it properly,

M615 Piston seals:

Verdict:

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.

Review: Shimano Deore XT M8000 with Race Face Narrow wide

On 10speed Formula/Bontrager Freehub:

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.25185797391_0cfdb76e37_o

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.

With this set up i used uncut CN-HG701-11 chain.

Shimano Deore XT M8000 I-Spec B shifter:

26307676250_68f1a4b4fd_b25193088823_b2f5dda76f_b

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

Down shifting:

  • smooth lever-action.
  • 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:

25023025415_969c733b3d_c

11-26T M8000 Cassette  & RD m8000 with original link & trek ABP hanger 

 

Pros:

  • 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.

If you want video proof that narrow wide works watch this video by Seth’s Bike Hacks

Me unboxing the 36T chainring

Down 50 degrees stairs test:

Steep stairs

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 have faster 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.

Review:BBB BSD-04 Anatomic Race-Black saddle- Uncomfortable

ncathis saddle has more cons than pros, it’s basicly butt torture for me.

the plastic on the sides and the plastic part that hold the rails will be pushed into your buttcheaks and will hurt when sitting on it.

i felt the saddle right where my butt bones/ischial tuberosities.

its very unconfortable saddle, the onyl reason i fot the saddle is because hte bontrager ssr saddle on my 3900 broke.

i now sue a Bontrager race RL wich flexes more and is thinenr btu still cmfortable.

Pros:

  • pretty durable
  • the front plate under the saddle did not breake
  • no screws popped out.
  • the grip,but can’t say how long it lasts becuase i got a new saddle as soon as i could

 

Review: 2015 Giro DND gloves

the durability, and wear resistance of these gloves are much better than then Remedy X gloves,because there is no horrible hook & loop strap that wears out.

I have used these gloves about the same time as the remedy x gloves but these gloves will last much longer.

my knuckle size is 21cm,  and i used size large.

Depending on your hand these might be a con or a pro: if you got abnormal big wrist bone and thick thumps these gloves are for you.

  • the thumb is bit too big for me
  • the wrist is too big for me.

 

Pros:

  • elastic part on side wrist to help with fit.
  • durable
  • very breathable
  • sweat wipe material on the side of the thumbs

Cons:

  • The seams inside,result in less comfort than Poc’s gloves,but nto so bad that I would not wear them.
  • no Velcro strap for the best fit
  • no touch screen support

Long term review: Straitline defacto pedals[Recommended]

Flickr album

Straightline Components flickr group

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 damage done to spindle threads.

IMG_20150805_165802 IMG_20150805_174302 IMG_20150805_165323

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.

Cons:

  • 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.

Pros:

  • Very durable,can take some abuse.
  • excellent construction
  • excellent grip
  • easy to replace pins
  • easy to service,one of the easiest on the market right now
  • many colour choices, will match most bikes

Conclusion

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.
