Title: 165x38mm vs 165x40mm shock....interchangeabel?
Post by: jimmyD on November 13, 2020, 04:45:49 PM: Can a 165x38mm shock be used in a frame that says its made for 165x40 (with a claimed 103mm of travel)

Im looking at a few chinese frames, one of which says it uses a 165x40mm rear shock.
My Rockshox Monarch xx shock is 165x38mm. will this be ok?

MTB specs still confuse me... :o

like the above poster said, it will reduce the amount of total rear end travel available to you. i'm not sure why you'd want to do this...a 165x42.5mm shock is easy enough to find.

Post by: jimmyD on November 14, 2020, 11:41:26 AM: Only reason im interested in doing it is because I already have a 165x38mm shock. Hoping to juts replace a frame and keep all the other components.

But thanks for clarifying that for me guys!

Any Idea which brand/store makes trunnion conversion kits to use 'old' 165x38 shock?
