Feb 14, 2021 · After a few pedal-strokes the rear derailleur completely gives out and the pedals drop to catch up. After much googling it says the most common thing is rear derailleur adjustment is needed, so I h...

This will sit on the inside and/or over the top of your chain on the front chainring which will help prevent the chain from jumping off the front ring.

Apr 21, 2024 · This is an easy fix albeit I will caution you, what I refer to as 'chain jumping' is one of the more dangerous scenarios when riding a bicycle. Each time it jumps, from pushing hard on the pedal, the worse it becomes. For the moderator, my experience comes from building over 400 bicycles, 2/3 of these vintage mountain bike conversions to road bike.

Nov 22, 2024 · The bike is a KTM ultra Flite from 2010 with 9-speed cassette Shimano HG50, rear derailleur Shimano Deore XT Shadow and front derailleur Shimano Deore with 3 speeds. Some weeks ago I started to have the problem that when applying a lot of power to the pedals, the chain was slipping (not jumping to another gear but just slipping).

If the shop doesn't use a Park Tool DAG-1 [derailleur hanger alignment gauge], or some other manufacturer's, to inspect, verify, and correct the relation of the hanger to 3 different points on rim of rear wheel at 180 and 45 degrees apart it is throwing parts at a bike.

Oct 3, 2014 · I've started to develop a problem in the rear derailer where when I shift to a higher gear/smaller cog, the shifter "jumps" multiple gears.

Great, I am already jumping small (30cm) holes, but am still scared to jump obstacles, that rise above the level. Maybe a cartoon box will be a nice start. I am afraid of hitting the rim of the curb with the rear tire, with all my weight over it, and ruining the tube and the rim. –
