We have been building a 3rd Air shox for the Yeti kits for several years that adds 11 more inches of travel to the entire skid, this is different than is done in Canada at Innersports. This system sucks of bumps like crazy and can pull high gears through the trails woops and bumpy terrain and allows pulling the front end up easy to wheelie , tricks and launch over logs exc,, The problem with this super plush suspension is that it kills climbing performance, So we took it to the next level last season. I install a luminated backlit button on the bars that when pushed it will totally lockout the shox for climbing, press again at top of climb and back to super plush, Its all done electronically and takes under a second to lockout.,, next level for sure!
