Hi, I recently got a FISCHER road bike from my uncle in Poland. I believe it's from a German bicycle maker. Details on the bike:
FISCHER road bike, chainstay protector says, "Shimano Equipped"
- Campagnolo Berlin 36 ETRTO 622x13c Rims
- Suntour GK/GL Hubs (F/R)
- Michelin Lithion Tires 700x23c
- ITM Handlebars
- DIA-COMPE Brake Levers/Hoods
- Shimano Exage Motion Brakes
- Suntour SL Front Derail
- 52/xxT (130BCD)Chainrings
- Dotek-FG-PRO6-170 Cranks
- Suntour GPX BB (1.370"x24 tpi & 70 mm shell size???)
- Shimano RSX (RD-A410) Rear Derail
- Suntour AP Cassette 13-24
- KMC Z-50 Chain (new)
I believe this bike through the years might have been modified... First, the brake's reach is a little too short. Even with the pads adjusted at the limit, the pad rides slightly off the rim (towards the tire) by about 1 mm. Second, the mixed drivetrain components (Suntour & Shimano).
First, I'd like to find out a little about the bike. Second, the BB is worn and at the moment I can't open it up (I already adjusted it to remove some play). What are my options in terms of BBs, better to just get a sealed cartridge unit? Third, the reach of the brake calipers is too short. Fourth, I recently replaced the chain and when pedaling hard (uphill) in certain gears the chain skips. I looked at the chainrings and cassette and they don't appear to be worn funny. I wanted to flip the cassette gears around, but discovered that the Suntour cassette has asymmetrical teeth that engage the freehub (thus they cannot be flipped).
I measured the old chain, it was over 1/8" longer at the 12th link, so I can assume that the rear cassette is in fact worn.
