This is the Trek 520 I brought home on the weekend. It appears completely original right down to the tires and I believe it's an 89' although the frame looks newer.
Can anybody explain the super long rear brake cable? Can I just cut it to fit? I don't have any bikes with areo brakes so I'm not sure how its supposed to look.
Biopace! I have never ridden any biopace bikes but I do know some riders who swear by them on their MTB's for traction on climbs. Can I swap out these rings and will standard rings fit on the Deore arms?
It has the stock 7 speed cassette with a 28 tooth low gear. I would also like to swap that out for something in the 32 tooth range.
And the 27 inch tires on an 1989 seem out of place when most bikes had 700c by this time. But then Cannondale hung 27 inch tires on their touring bikes until 1990 or so.
