Pictures of what you speak of are always helpful. Well, to me anyway. (Pictures including your bike, and the packaging and product you had just recently purchased.)budegan wrote:I'm baffled and wondering if someone can advise me.
A couple of weeks back I snapped my rear hanger. I ordered 2 new ones (a brand called Pilo) a replacement and a spare, and this week got around to putting one on.
First ride on it yesterday and it snapped.
So in the evening I put the spare on, rode on it this afternoon (in a crit) and that one snapped!
I've had a quick look online to see whether whether it's Pilo that's the problem, but nothing is leaping out.
Worth mentioning that I think the original hanger breakage was due to the rear mech (di2) being faulty. It's now been replaced and today's breakage occurred with the new one on.
Also worth mentioning is that I've been using a hanger alignment tool when fitting.
You mentioned riding in a crit - is this a road bike you're talking about? (Apologies, my knowledge of MTB-ing is severely lacking. So if you MTBers do crits, again, I apologize.)budegan wrote:Unfortunately I've broken down the relevant bits (removed the chain etc).
TBH there wasn't much to see anyway other than a snapped hanger!
This is very good advice -JayKosta wrote:When you used the alignment tool, how much 'alignment bending' was done? And after installing the new hanger, did you go thru a test of having the rear wheel off the ground and going thru all gear shifts - and visually SEE and HEAR that everything was running with good alignment.
And make sure there is enough clearance between the deraileur parts and the sprockets so there is adequate room for everything to move without mechanical interference.
