Alert: this cassette conf cannot be used in all touring locations because of poor support. I use it only in 1st world countries.
The largest cog at the back is about 12-14cm. The length from hole-to-hole-opposite is about 10.5cm. The length between adjacent holes is about 7.86cm. The hole is the thing by which the cogs are attached to the bike and there are four holes. "Mega Drive Train" is written on the cog-thing. The derailleur-thing is LX Deore Shimano. I upgraded to a new chain PC-951 but it jumps a lot with cogs 2 and 3 (did not jump that much with the streched old chain). So I want to upgrade to new cogs/cassettes. The cog configuration is:
- largest cog: 32 teeth
- smallest cog: 11 teeth
- largest cog: 48 teeth
- smallest cog: 26 teeth
so how can I know which cassettes I can buy? I can find a variety of cassettes advertised for "11-32 cassette" but 26-48 returns none in eBay, perhaps a calculation err (any fast way to recheck?!).
- Can I change the number of cogs?
- If I can change the cog amounts, are there some tables to look for good tested configurations?
- I have no clue why just these cog amounts were selected to my Crescent Sport bike. What would be a good cog configuration for touring?
- Which cassettes and cogs would you recommend for low-cost quality choices (a bit like SRAM PC-951)?
