mataz Posted July 29, 2013 Posted July 29, 2013 My other half is currently running a SLX 38-24 Crankset, but she's battling a bit on really steep hills so I was thinking about making it a bit easier for her. She likes the 2x10 though so I don't want to change to a triple. So: - Is it possible to run a 22 tooth inner ring or is the jump from 38-22 too great (have heard that 14 is the recommended max)? - If this is not possible, do Shimano bring out a 36-22 combo or could I use blades from a triple? Thanks.
Ryanpmb Posted July 29, 2013 Posted July 29, 2013 A change to a 11-36 cassette (if you're not already running one) will make a difference.
arendoog Posted July 29, 2013 Posted July 29, 2013 (edited) That jump is to high.Cassette change might work11-36 Edited July 29, 2013 by Blitzer
Iwan Kemp Posted July 29, 2013 Posted July 29, 2013 - Is it possible to run a 22 tooth inner ring or is the jump from 38-22 too great (have heard that 14 is the recommended max)? No. Rule of thumb is a 1.5 jump. For example:26 - 39 (or 26-38 in Shimano's case)24 - 36 (or 24-38 in Shimano's case) - If this is not possible, do Shimano bring out a 36-22 combo or could I use blades from a triple?As long as it's 10spd (or compatible) chainrings it will work. You can buy aftermarket chainrings in those sizes. As long as it's Shimano compatible it can be any make.

mataz Posted July 30, 2013 Author Posted July 30, 2013 11-39 cassette then... Does such a thing even exist? Have only seen up to 36 tooth (SRAM or Shimano) on a 10sp...
MTBc Posted July 30, 2013 Posted July 30, 2013 Does such a thing even exist? Have only seen up to 36 tooth (SRAM or Shimano) on a 10sp... No but you could build your own. http://forums.mtbr.com/drivetrain-shifters-derailleurs-cranks/10s-11-39-cassette-647456.html
johnw Posted July 30, 2013 Posted July 30, 2013 KCNC make a 11-38T MTB cassette.... but at a cost.Will be cheaper if you can get a replacement front 22T chainring to replace the 24T?
