Shimano cx50 chainset
Since I've had shimano cx50 cranks on my commuter/cross bike they've worked themselves loose twice causing problems too far away from home for comfort!
I've had plenty of other cranks and this has never happened before. I think it's a problem with the internal threads on the non-drive side.
About to order another set of cranks but unsure whether to go down the shimano route again (even though I have perfectly functioning 105 & ultegra cranks on other bikes).
