2 Months Review of TRP Spyke caliper & Spyke ML800 & ML930 levers

I have used these brakes for over 2 months on 2 bikes without any issues.

And I have put these brakes trough their paces.

I don’t think I have to wait much more than 2 months before publishing this review, as these brakes are mechanical brakes, So not much can go wrong, But I will update you if there is something more to write about.

Both levers offer excellent feel, but the ML930 has a smooth surface on the lever blade, the ml800 has a textured surface with a Spyke logo, but the white paint on the logo wears off after few weeks or days.

Spyke Levers:

The Spyke logo on the lever blade actually gives more grip as its engraved, But for me It does not make a difference.

Pros:

  • Rech adjustment so these levers will work well for a kids bike.
  • Excellent barrel adjuster, it fits well into my fingers and makes it very easy to adjust the wire tension.

Cons:

  • up and down play in the lever blade
  • No hinged mount, so you have to remove the grips, but for me this is not a deal-breaker.

ML930 levers:

The lever body has visible flex while braking, But I can’t notice it while braking.

TRP offers a carbon version of this lever, which is ML940.

Pros

  • Excellent barrel adjuster, it fits well into my fingers and makes it very easy to adjust the wire tension.
  • Lighter than the ML800 Spyke levers
  • Hinged mount for easy removal
  • Rech adjustment so these levers will work well for a kids bike.
  • I have these levers on both of my fuel ex 29ers, and they the levers on both survived crashes, on one it survived over the bar crash, where the bike landed parked upsidedownon the other bike it survived a fall about 1 meter from a concrete wall.

Cons

  • Same up & down play as the Spyke levers

TRP ML 930 levers fittet on a 800mm Race Face Sixc handlebar, I have them setup 3cm from the grips.

Calipers:34472227101_6dcff0e7c5_o

The dual arm has is quite harder to pull up compared to Tektro single piston brakes, but this does not bother me.

the Spyke brakes offer one finger braking, as powerful as the Shimano m615 brake, but without the issues of leaks and impossible to get seals.

The Pad mud cover does not protect the pads that much, mine were had sand on them, when riding in wet conditions, there is no way to protect the pads, things will get in the rotor and can get stuck and make noises.

Pros:

  • well engineered, caliper, the narrow design gives good clearance so you won’t hit your heals on the brake.
  • the 3 mm piston adjustment, makes these brakes easy to set up.
  • barrel adjusters that are easy to use and by figners fit nicely on them.
  • rubber seal helps to keep dirt from coming in the hoses.
  • Easy to align The calipers: To align the callipers with the Hope floating rotors, I screw in the outside pistons about ca 3 quarters, and the inside piston about ca 2 quarters, then I tighten the caliper bolts and loosen the pistons, which leaves me with perfectly aligned brakes.
  • easy to assemble, & get the cable clamped.

Verdict, these brakes performed well so far, so far I don’t see any reason to switch to back to hydraulic brakes.

To keep the brakes having consistent braking power and modulation, you only have to use thread lock on the piston threads and have proper wire tension, and check it regularly. And of course, adjust the pads inwards as they wear out.

The semi-metallic pads give excellent g braking power, and they held up well for a few months, and I think they will last a few months more.

Long Term review Shimano M396 Brake

I wave these brakes on a trek 3900 I Rebuild from leftover parts from my other bikes+ some new ones, So this is a bike I don’t ride often, But 2 years ago I rode these the bike with these brakes the whole winter, in various temperatures down to -11 Celsius ,And of course I used the brakes very often, but I noticed oil leaking trough the master cylinder on the left/rear brake, So I checked it it was the Torx screws that were the issue, but that was not the case, the threads I in the master cylinder were destroyed, they were polished to powder, so the screws did not hold the seal and the lid in place properly, so I ordered a new complete lever, but after only 2 trips about 10 Km each trip, the part which pushes the got scratched,and this was not caused by a crash, these brakes are just too weak.

New lever

The lever body is flexing when you press the lever blade all the way, Which I probably why the part that pushes the piston in gets scratched, and why the threads fail, and why the brake leak.

But there is significantly less flex in the 396 than m615, the m615 flex about halfway,and the m396 flex at near to all the way.

I had not had any issues with the seal in the calliper, or the calliper, But I have not ridden the bike with these brakes as often so it’s most likely why.

Master cylinder,failed threads
Failed Threads
The spring & the black plastic part had no damage.


New Lever

Verdict:

This is a way too flexible & weak brake, I strongly advise against buying these.

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,

Extra Info

M615 Piston seals:

IUY 21.1 25  3.19 78 NOK

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.
