Updating My New (Old) Norco Bigfoot
I bought this Norco Bigfoot MTB after finding it on an online classified ad website (I'm partial to the brand and I've never seen the triple-triangle frame on any of their other bikes):
It's a one-owner bike and in pretty decent shape for its age. Other than the tires the parts all seem original. The braided cables look thick enough to support a suspension bridge.
After a brief but violent struggle to loosen the seat post and tightening the threaded headset, I took it for a long test ride. The bike has a few issues which is not surprising for a well-loved 20-year-old bike.
Raising the seatpost left my handlebars about 3" below the seat. I added a riser bar but it pulled the shifter cable housings taut, and my Ergon grips pushed the STI shifters up against the bend in the bars. That's okay since I already planned to update the cables and swap the STIs for some thumb shifters. The real issues are with the bottom bracket and the brakes.
The bike has a Shimano Exage 300EX gruppo with Biopace crankset. After reading Sheldon Brown's take on Biopace, I've decided to keep it as is. Unfortunately, the bottom bracket is clicking in an all-too-familiar way that tells me that it's on its last legs. Other than rebuilding the bottom bracket on my BMX as a kid (using a hammer and screwdriver for want of a spanner, plus packing the bearings with petroleum jelly) I've always let the LBS handle that issue. When I approach the LBS for some parts, what type/size of bottom bracket do I ask for? What other parts will I need? How about a spanner?
As far as brakes, I want to replace the cantis with some linear-pull units. Since I'm ditching the STIs anyway, new (linear-brake compatible) brake levers are a given. Are there any other issues that I should be aware of when swapping cantis for linear-pull?
Sorry for the long post, and thanks for any and all replies.
