Ok I need some more help.
After recently mashing up a nice wheelset (rear anyway), I'm taking the opportunity to replace my totally unrealistic 11-23 cassette with something a little more "real". I only did four rides and 11-23 was very tough on me (not done much riding these past 18 months).
I'm new to the roadbike, having ridden MTB and commuters for years now, both on 12-27 cassettes and standard MTB rings … - more than comfortable with these ratios.
My question is, as I don't understand the workings of the ratios ….
My roadie is running a 53, 39 upfront, in order to achieve a ratio similar to my MTB and commuter what cassette would I need to run?
I'm not changing to a compact or triple as I spent good money on my crank so even if I cannot match the ratio, something a smidgeon tougher than my 12-27 wont hurt too much.
Any links to charts, tables, info on gear ratios would be a great help also.
Oh, may have a super lightweight 11-23 Recon cassette for grabs soon also, it weights just 87g and has only done around 60 clean, dry miles.
