What 165 mm cranks for enduro?

Phone a friend, 2 pairs of hands are better than one.

Also, make sure you've got a decent bench vise and that the tool's properly tight in there. If it can move it puts pressure on the leading edge which can cause the vise to break.

And if I recall it’s a left hand thread?

I feel a video is required for this method with disclaimers 😁

I've broken one crank bolt and zero allen keys. And the busted bolt was never going to come out any other way. The remains came out by hand once the tension was off.

Think about that one for a second...

You’re right that’s not the one that’s left hand. Pedalling tightens it further to the point of nearly impossible to remove

I normally take my front wheel off and support the bottom of the lefty on a bit of foam. Wedge the left side crank into the ground and stand on it, then apply all my weight and force to get the crank bolt out. I’m just struggling to visualise how you do his with both wheels removed, hence the video request

Just thought I’d add an update on the original query in this topic. I ended up ordering a set of 165 mm Race Face Turbine cranks directly from their US website. However, I also got a stiffer spring for the rear shock (550 lbs linear – the original was a 500–610 lbs progressive). My reason for getting the new spring was more to try to get a more supportive mid stroke and make the bike a bit poppier than it was about trying to remedy the pedal strikes. I did one ride with the new coil before I replaced the cranks, and I immediately noticed a more upright riding position with a less wallowy rear and fewer pedal strikes, although this particular ride didn’t include chunky climbs of the sort that usually cause the most pedal strikes. Then I installed the new cranks and did another ride in some of the worst terrain in my area for pedal strikes. It wasn’t completely strike-free, but there was definitely a vast improvement over my previous setup. There were at least two or three occasions where I was certain I would previously have hit the pedal on a rock but cleared it this time. I can’t be sure if it was the stiffer coil or the 5 mm shorter cranks that made more of a difference, but I’m very happy with where the combination has got me.

Some bikes and their leverage ratios/ progresivity curves just mean you’ll blow through even a heavy spring. Some coil shocks like the DHX2 are also just more linear in their travel. As an example, my previous bike had me running a 550lb spring on a DHX for my 90kg weight. My new bike with an ohlins shock has me on a 388lb spring for the same weight. Different damping philosophies.
