tiff shifting on your bike
If you're experiencing stiff shifting on your bike, there are a few things that could be causing the problem.
1. Check to make sure that your derailleur hanger is aligned properly. If it's even slightly out of alignment, it can cause shifting problems.
2. Possibility is that your chain is too tight. When the chain is too tight, it puts extra tension on the derailleurs and can cause them to work less efficiently.
3. There's something wrong with the shift forks inside the transmission. The forks can get bent or damaged, making shifting gears difficult.
4. If you're having trouble shifting gears, you should be to check for any obvious problems like a loose shift knob or worn-out bushings/bearings.
5. Check your chain regularly. A loose or damaged chain can cause your gears to slip or change unexpectedly.
Finally, make sure that your shifter cables are in good condition and properly adjusted.
If they're frayed or stretched, they'll need to be replaced. If you've checked all these things and your shifter still feels stiff, then it's probably time to replace it.
