OumersBicycle Crank Arm, Bike Crank Lest Arm with Bicycle Crank Puller Crank Arm Left Available in Diamond Hole 170mm Bike Crank Ram Replacement for Mountain Bike Road Bike

I recently converted my Trek Marlin 7 to an ebike, however, I obviously didn't screw the previous left crank arm on tight enough, because at one point, it fell off.Unfortunately, what I found was that, because the mounting hole within the soft metal of the aluminium crank arm had become misshapen (because I pedalled with it a lot while it was semi-loose, which I didn't realise at the time).Now, after that, no matter how tight I put that crank on, it would always eventually work itself free, due to its misshapen hole.I was left with no choice but to buy a brand new crank arm with a perfect mounting hole. And that is this. It works great now and never comes off.This was surprisingly cheap too, especially when you consider that it comes with a crank puller too.All in all, good quality.I'll leave an update in the future if anything changes.

Installed on a stationary bike that I smash everyday, after two weeks it's still perfect

This crank arm was exactly what I needed to repair my mountain bike. I appreciated the detailed photos and measurements provided in the product description to confirm a proper match. This item was a great value since it included the crank arm as well as the removal tool.

preis-Leistung gut, schnelle Lieferung

hard to start threads, add penetrating fluid (wd40) and good to go, works well, took Crank off easily.
