So I have an old (1994) Trek 370 that I am training on (planning to ride a century in Death Valley in October for the JDRF, see my post in charity btw).
Anyways, the chain is slipping at random on the rear. I figure its a good time to replace the oem cassette and chain (bike was given to me so I have no idea how many miles are on them).
I've been looking at this: http://www.amazon.com/Shimano-CS-HG3.../dp/B000F5LLVC
Is this a good combination of gears? I'm a bit lost when reading the gear articles. I figure a bit of gear would help as the Death Valley ride has a decent (1500ft elevation change at the end) amount of hills, then again I'm working hard in the gym to get my legs as strong as possible.
1. Correct selection for my bike? If not, how can I tell?
2. Gear selection: Better suggestions? Can I convert the bike to 8 or 9 speeds? From what I read I'd need a new rear hub correct? The RD (and front) are the stock Shimano EX components (300EX front/400EX rear).
Thanks for any/all help.
