Race Face Turbine VS Atlas cinch cranks

For me, the fastest & easiest solution when the awful Shimano M552 cranks failed, was to get turbine cranks. The cranks on my trek 6300 bike failed, so I de sided to switch to my trusted Turbine crank, plus crisp King bb, so I decided to try Atlas cranks, I thought I would notice the difference, and I did.

I am about probably between 72-80kg, I ahven’t been on a scale in a long time (but this number varies on how much stuff I got in my backpack, I have not weighed  in a long time, so I am probably heavier now.) with all the gear on

I have read reviews saying that there will not be noticeable differences, that was coming to a heavier reviewer, but pink bike review stated that there was a difference, their review is good so take a read d: https://pinkbike.com/news/race-face-atlas-cinch-crankset-review-2016.html

The crankset is quite similar looking, but there are several differences, the turbine cranks look pretty similar to the Atlas cranks, but the Turbine have a lot more material shaved off in arm where the bolt is & on the tip,  the is also a difference in how much material is shaved off behind the crank, the Atlas has more material near the pedal.

Both of the cranks have a nylon preloading, which has a small Allen screw, which was easel rounded off even though I was very gentle.

So as soon as Cane Creek Preloader came on the market I ordered it for all the cranks.

Here is a pictures of it installed.

for commuting, or xc/light trail, these cranks were stiff enough, but on rougher trails, I could feel the difference in stiffness or another technical riding. I think turbine cranks have a good stiffness compromise & of lightweight.

The crank ground on a concrete wall, I was unharmed, it did not even hurt.
My right shoulder slipped turning the bars to the right, resulting front wheel dropping off a wall, and me falling down with the bike about 1 meter on concrete.
the reach dérailleur hit the top of the wall & grinding along it, the fork first went off the wall to the right but the rear was grinding it eventually fell down and the fork hit the wall and eventually, the whole bike went down with me.

First ride with Atlas cranks:

Even before riding the cranks on the trail I could feel the difference in stiffness, just by a quick test in being on the bike in the kitchen, I tested a lot of positions, but then I took it for a spin on the trails some days later.

The first ride on the trails, I felt the difference, even though my frame is quite flexible in the BB area.

I could feel that the Atlas cranks were stiffer while riding technical trials.

  • The bolt has bad tolerances, causing wear, this is the case for both Turbine & Atlas the cranks of course

Verdict:

I think turbine cranks have a good stiffness compromise & of lightweight, so perfect for a commuter bike or for lighter riders.

I am all for everything that gives me better control, and stability, which both Turbine and Atlas cranks gave me over the cheaper much more flexible Shimano cranks I have ridden in the past.
