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.
