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

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,

2016 Shimano Deore XT M8000 Ispec B shifter mounted to Deore M615, (there is no B on the brake but its compatible jsut look for the I spec B holes) i know  the brakes are bit steep in this picture but I have tweaked that later.

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.

2015 Swix RaceX base layer jersey high neck

I got this underwear jersey in medium.

Pros

  • very comfortable against the skin
  • the sleeves are long and go past he wrist so your gloves go over them, witch is perfect for me as a rider.The wrist area of the sleeve can fit 2 of my hands but still leave room, when fully stretched.
  • it stretches in all directions so when you get bigger muscles it will still fit,as you can wearing padding underneath is not a issue, or if you are muscular it won’t be a issue either,but I wear the pads over the base layer,so you don’t have to take off the base layer to take off the pads,

biketec mini verktøy set anmeldelse- slarkete

 

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.

 

jeg

slark, umbrakoskruene som holder verkøye sammen løsner altfor ofte,
