A lot of people over tighten the pre-loader on Shimano cranks in my experience, I used to do the same as it's very easy to do with a Shimano and it will ruin your bearings pretty quick.
What do people use to tighten them with? I’ve got an Ice-Tools one that fits in your hand, so hand tight only.bobbo89 said:
Yeah finger tight is all that's needed but some people almost treat it like a bolt and proper nip it up good....
I've had a crank arm fall off on me more than once so I'm definitely guilty of over tightening the pre load and crank bolts.Will be more careful in future, hopefully this is my issue.

It's worth buying a Torque wrench for the bike, here's a recent review on some https://www.cyclingnews.com/features/best-bike-tor...
This has just popped up on my youtube videos, which may be of help? https://www.youtube.com/watch?v=gFbvFu3NER4

Thanks for the replies all.
I've been looking at Sram GXP, the look similar to the Shimano ones I've been using but can anyone confirm they're compatible before I go ahead and order?
Cheers
GXP aren’t compatible, the non-driveside end of the shaft is 22mm, shimano are 24mm.I've been looking at Sram GXP, the look similar to the Shimano ones I've been using but can anyone confirm they're compatible before I go ahead and order?

nice. pics?Managed to get the frame from CRC last year when they were half price, plus another 10% off. Wasn't fussed on red at the time but that was all they had left in my size but it's grown on me since
Picked up most of the rest second hand bar the forks which are probably overkill for what I use it for

In lockdown, SRAM GXPs were hard to get. I managed to find one but when it died, I bought a cheaper replacement which, in fairness, has lasted for 3K miles to date and still seems OK.
I also have a couple of bikes with Shimano BBs and you'd have to be really trying hard to overtighten them but as you're having problems with both bikes, I don't think it's an alignment issue. Are you fitting the spacers correctly?
