Re-configuring a 90s cro-moly mtn. frame for 700c wheels?
I'm doing some searches but not finding exactly what I need....
I have an early 90s Schwinn HighPlains mtn. bike (low end comfort bike) broken down and boxed up due to moving on to better/more up-to-date hardware. I "rigged" it up to be a SS commuter for a while when I lived close to work, but the brake setup I tried was a little iffy (cantis with LOOONG arms so the pads could reach the rim brake surface) and eventually decided not to ride it since I was not confident if I could stop.
Now I'm faced with moving and MAY end up living close to work again (within 10 mi.). If that happens, I would like to try commuting by bike again but if I'm around 10 mi., I want my setup to be better.
700c wheels and 32 tires fit well and if the brake bosses were moved up, I think it would be a nice touring/commuter/cyclocross rig with more solid V-brakes. I want to run 700c's due to the potential distance of the commute. However, I have no idea how difficult it would be to remove the old bosses and rebraze 4 new bosses on, if it's possible, how much would it cost if I could DIY, or if it's even recommended?
It's a nice lugged frame that I would like to try to ressurect, but if I'm better off just buying a cheap touring frame off ebay, I'll do that! Any input/advise is welcomed!
I've done this exact conversion on my MTB that I used as a commuter for school. I made a jig to hold the two brake-bosses at the precise spacing. It was simply a 2x6" metal plate that I drilled two holes into and then bolted it to the brake-bosses. Then I used a Dremel cutting disc and trimmed the brake-bosses off as close to the tubing as possible. Moved the bosses up about 30mm and brazed them into their new location with an oxy/acetylene torche. Took about 2-3 hours total with clean-up and painting.
