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 75kg, (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.

Turbine:

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.

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

 

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.

Shimano Avilio FC-M410 review

I have only used this bike as spare bike in the summer, but I used the bike one and a half winters, the same thing happen as the Acera cranks, the square taper hole had damage, it did not show as much as this bike was not used as much,I noticed it before any huge play, as on the Acera crank there was damage to the corners, there were some scratches and small crushed metal,but I also noticed the UN26 bottom bracket was worn out, it was barely used, just used few days, they lasted quite long before, But I did not check the play for play in the bb.

These cranks are about as flexible as the Acera cranks.

these cranks don’t work well with 1x set up as the offset of the middle ring is too far outwards, so without spacers, the drivetrain will be very noisy.

So, of course, these cranks and BB were removed, I can’t have components like these on a bike I ride because I will destroy them, For me, it’s not saving money, but wasting money & time, Only High-end components for me!

These cranks came with triple rings.

 

Shimano Acera FC-M361 Long term review-Revised – Ridden to destruction

35395054834_c97965866b_o

4th August I posted the review, but Since Then the crank was completely useless.

Time of use:

I have ridden this crank at least one season, but after I got my new bikes in 2015, I only rode this crank few weeks and days each year.

Too Flexible

On my trail bikes, I have been using Race Face Turbine Cinch cranks, and they are very stiff, but the Acera cranks are not, it’s noticeable while track standing or on technical climbs.

When track standing I can feel the cranks flexing, which I have not experienced while riding on Hallow XT cranks.

So far no damage to the threads for the pedals, like on the M522 cranks.

But these cranks are clearly not good enough for me.

The cranks are quite flexible,

I destroyed the cranks.

 

Failed Shimano Acera FC-M361_0401
Picture showing the left crank arm with crushed metal, the damages on the corners is also quite visible.

 

A few Days ago the crank looked like it was in perfect order, but I took the bike for a short side-walk ride, and after doing a inspection on the bike  I noticed  I managed to bend the spider leg on the front/ to the right of the crank. after a closer look Isaw the square taper hole in the crank had tiny alloy ”spaghetti” & when sliding on the crank on the tapered square axle I noticed that there was a difference in resistance on each angle, might be due to wear caused by too flexible crank,I am about 75kg with all the gear on.

A few days later crank arm to loose after about 14 km ride, with some bike-path and some light xc trails, I torqued used Loctite 243 bolt thread, I torqued it to spec, and I left it to cure, the next day I checked the cranks as I was Already working on bike, I noticed creaking sound from the BB area, so I inspåected it, I cocked each crank arm in all directrions,I noticed the left was making the noise, I then removed the bolt, and inspected it further, by rocking the crank arm, doing this I managed to take it off using my bare hands

I abused them but not much:

I have jumped the bike with these cranks, dropped of concrete walls.

The hardest abuse these cranks got must be the time I landed on a stair step, with the pedals after jumping.
