Casette and Shifting

[JJDT]

After the Magalies Monster my son showed me that the first 3 sprockets on the casette is loose on his bike. I'm still learning all the technical stuff and not sure if it just came loose because of the rough terrain. Can this be fixed or should I source a new casette? It is a 10 speed.

 

Now onto my own bike. I have replaced the rear derrailer and the cable in January this year. Had a bike accident and was off for 8 weeks before I started riding again. The up shifting is not bad but it requires some effort very hard and the down shifting is horrible. When I shift down nothing happens and when I shift again it just jumps to the recent gear position and then it reuires an up shifting to the gear originally selected.

 

I have loosened the cable a bit(basically pulled it to tension with my hand before tightning) because of the hard up shifting but did not help much. Adjusted at the shifter but with not much success. At first I lived with it but now that my fitness level increases and want to go faster the shifting is now a real problem.

 

Help...

1. ensure lock ring to mount cassette onto freehub body is tightened OK. It should be easy to find the problem and fix it rather than buying a new cassette

 

2. possibly your cables need lube inside their housing. If they have been washed and left for a while, corrosion can seize the cables. tweek the cable where it is exposed on the frame without using the change levers, it should pull and release easily. Check that none of the cable housing ends have been kinked in the crash. Lube deraileur hinge points.

 

3. disconnect cable from derailleur, then hold end of cable and try to use gear lever - if cable moves freely, then your derailleur needs oil. If cable is stiff to move, cable needs oil.

 

Good luck - there's always satisfaction if you manage to trace problem yourself!

Start with new cables, sounds like yours are gunked up. Also get your LBS to check hanger alignment, if you came pipe hard enough to put you out for 8 weeks I'll almost guarantee it's out.

 

As for the loose cogs on the cassette, the first few cogs aren't attached to the spider so they will be loose in that sense, but if they're moving around chances are you'll need to tighten the lockring. If you don't have the tool that's a trip to the LBS as well.
