I'm mechanically inclined, but I don't know much about modern bicycles. I have a Rocky Mountain C70. Since I live in the city, I'd love to have a second set of wheels that aren't knobby for the paved trails around my area.
I know a lot of people say "just get a second bike", but I don't have the storage area for that, so it's not an option. It's either this project has to work out or I just have to ride my knobbies.
I'm investigating getting a second set of wheels for only occasional use. I've decided to field as much stuff as cheaply as possibly from chinese supplies like ali express, or find used stuff on ebay. It appears I can fit 700c tire/rim combos on my bike because it's setup for 29" tires. I don't want to do a cassette/rotor swap every time, so I'm going to purchase those as well so I can drop the new set of tires on like a nascar pit stop.
I need help with the shopping list and any potential "gotchas" before purchasing items.
What I've found so far is a cheap pair of 700c rims on aliexpress with spokes already installed. The freehub says it's shimano compatible, but for an 11 speed.
That gives me my first question, will the 11s rotor be long enough to fit a 12speed?
What about rotor/hub width, is everything a standard width? Once I have these rims and install the brake discs, will they line up into the pads?
Do I need to worry about axel sizes?
What else do I need besides 700c rims, tires, brake discs, cassette, and tires?
