You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
My son has ridden the last 3 Saturday with his club and I've been doing other stuff (I normally coach with the club so am in the vicinity, if not always in his group). He's not bad at cleaning bike etc so has done it all himself. Drivetrain was looking a bit manky so decided to give it a decent clean this morning. Instantly thought it was noisy and found that the chain was on the wrong side of the mech plate between the 2 jockey wheels. Easily sorted as chain has a power link, but perplexed as to how it happened !! Definitely was OK last time I rode with him a few weeks back, and last time I cleaned it, maybe 3 rides back. He says no one has split the chain, though he did get a big stick jammed a few weeks ago.
Could a stuck stick in mech twist it open enough for chain to get onto wrong side ?
Or is a ghost in my garage messing with me ? 😀
It's just about rubbed the plate away, so new mech ordered (xt, 10 speed)
Blame Trick or treat, or Wiggle. 😉
Hmmm 🙂
Junior wouldn't know how to split a powelink and he would remember if a coach had done it due a mechanical....
It was correct a month ago....
Weird !
Could junior be being less than honest ?
Yes, a stick could easily twist the mech like that. The instant it sticks you've still got full power going through the pedals for the split second it takes to figure out something is wrong.
actually.. its easily done on certain XT mechs.. I did it and corrected it after a month or so. I also noticed a co-workers XT mech (diff to mine) also had exactly the same issue and carefully pointed it out.
my theory is with a brand new chain and mech it doesnt touch, but once the chain has a little stretch in it it rubs
Useful, sounds like that's the mystery solved, I blame the stick !!
Found new inner plates on eBay Italy for £18, so at least not a new mech at this stage
UK RRP is £8.99.
Have a search with the UK part no and see if anyone has them.
5Y0 1000 for SGS (long cage) out of stock at Madison
5XC 0910 For GS (mid cage) in stock at Madison.
Both RRP at £8.99
Chain stretch can't make it rub though. It was either wrong in the first place and went unnoticed, or it was moved past the tab in a random trail incident.
^^ many thanks, will have a search or call LBS in morn, thanks
No worries
Just checked - you need to search with the full length part no, not the abbreviated UK one.
You need Y5Y010000.
Many thanks, found one !
