|   Gear ratio question | Psychler
Oct 15, 2001 6:16 AM | | I am running an 8sp system...Sram 9.0sl and XTR rear cassette (12-32), 36 middle and 24 small (no big ring)....110 spacing, 5 bolt
I need new rings and cassette.
I may only be able to get the 11-30 XTR ti rear cassette, thus losing my lower gear (32) (which I use)....
What would I have to do to the front middle and small rings to get the same ratios with nice smooth transitions? |

| how about a 28/38 with an 11-32 SRAM cassette? | scrappy-doo

You should be able to find some old-school (ie cheap) rings in a 28 and 38 size. Maybe check with cambriabike.com or have your local shop check the quality bike catalogue. |
