More Speed Needed - Hybrid Bike

Does it makes sense to buy a women's seat for man's mountain bicycle?

Which chain should I buy to replace the one on my Specialized Rockhopper 2016?

New chains are a standard length more or less. You’ll need to remove some links to make it the correct size. Any 10 speed MTB chain is fine. KMC is a good brand. You need a chain breaker tool to do ...

How do I tell what parts are compatible with a new frame?

STIs: Compatible without issue if you want to stay with a drivetrain setup that's compatible with 2x10 Shimano road, which you probably don't. Cranks: Not really compatible; will physically go on bike ...

Shimano FH-6800 rebuild or replace?

There are no thru axle FH-6800 or WH-6800 versions. The next/new Ultegra will have some, but as of now I don't think think any thru axle hubs or wheels that say Ultegra on them are really out in the ...
