I've seen that happen to 3 riders... It can be very costly!Personally, I don't like or have them on my bikes. But you can still send the mech into the spokes, so be warned.
Might a plastic disk not help at all?I've seen that happen to 3 riders... It can be very costly!
A plastic disc isn't going to help prevent that, so set your rear mech endstops properly.
Their purpose in life it to prevent the chain going into the spokes due you folk that don’t have a clue on how to set up the stops on the rear derailleur.
I’ve taken them off all my bikes and never had an issue.
I suppose you were born with the knowledge to repair your bike?you folk that don’t have a clue on how to set up the stops on the rear derailleur
I suppose it depends on how big the protective disk(disc?) is and where the mech makes contact. In all 3 cases I witnessed, the end of the derailleur contacted the spokes in the position 'B' in the example picture below. A plastic plate extending only as far as 'A' wouldn't have helped.Might a plastic disk not help at all?
Or at least, with the noise, tell you pronto that something is wrong before it gets worse?
advice: If anyone's bike ever falls over on the mech side, check things before riding - I once stopped spoke wheel damage on another bike by doing this.
I over-adjust it until I can't select that gear then back it off just enough to allow me to.Ok so I understand indexing and the concept of the limiting screws. The gears are nicely indexed so stop properly at the largest cog. How do I know where the limiting screw stops it at as when in first gear I can’t change to below that to know the limiting screw kicks in?
It can be very costly!
Pretty much as with this rider...Last time I did this was a few years ago but it cost me an XT clutch mech and hanger (plus riding home on a ghetto single speed)
We didn't know which had come first... broken hanger or mech in spokes.I was in a group of about 30 riders on the Costa Blanca. We had just hit a small hill and were starting to power our way up it when we heard a loud noise and a stream of expletives coming from the back of the group. A rider had just tried to change gear and his gear hanger had broken, sending his rear mech into the wheel. Several spokes were broken, his mech was hanging down into the wheel and the chain was mangled. We were about 30 miles from our hotel, in the middle of nowhere.
