Day 1 of my first geared bike build. I picked up this 89 Muddy Fox Courier Comp for £40. She's seen better days but the frame has a certain charm about it I couldn't say no.
My previous builds have all been vintage road frames and fixed gear so this time I wanted something suitable for long distance/touring. The frame is the only thing I'll be using so replacing parts with new/ whatever I can get my hands on for cheap. I know mountain bike frames have different sizings to road bikes/single speeds and considering my lack of knowledge with geared bikes in general, I was hoping for some advice.
I'd like to replace the 26" wheels with 700c. Tyre clearance, brakes and wheel axle/rear drop outs width are the potential issues. Rear drop outs measure up to 130mm so 1) is it possible to find a wheel like this pre-built maybe off a hybrid bike or something? Or would I need to use a mtb free hub and lace it to a 700 rim? I tried out a 700 wheel I had lying around on the front and plenty of tyre space. Frame + fork also have the drillings for caliper brakes, if I decide to go that route.
The plan for gearing is to have a 1x drive train with a 9/10/11 speed cassette. In terms of ratios, I have a few numbers, which mean little to me but some of you will know. 2) If I were to ride something between a 40 - 46T up front and 10/42 or 11/40, does this sound viable for mostly road use? I guess something generally suitable for climbs with a decent top end on flat is what I'm after.
Next problem is bb spindle length. This one here is about 122mm, which is no use with a single chain ring, so 3) do I buy a bottom bracket and 1 ring crank set first, then decide on cassette size at the back? What are the possible issues with chain alignment (if any) in this situation?
Cheers in advance and I'll keep you posted as and when things progress
