Another short-chainstay bike, this one for Minh, who already has a couple of other frames from me. He wanted to try jumping on the short-stay bandwagon, and I was happy to oblige. He didn’t want to do anything weird with the chainline, but wanted the option to go super short, so the compromise ended up being that at the shortest chainstay length setting (16″) on the sliders, the bike will only fit a 2.1″ tire. If he wants to run something bigger, he’ll have to slide the wheel back 5-10mm.
-For 29″ wheels, 100mm travel tapered steerer suspension fork, sliders for SS or 1x use.
-70.5 HTA and 72 (effective) STA. 86mm trail.
-63.1cm front center, 103.4cm/40.7″ (sub 41″!) wheelbase.
-59cm ETT, 44cm seat tube.
-32cm/12.6″ BB height.
-40.6cm effective/41cm actual chainstay length (that’s 16/16.1″), clearance for a 2.1 at the front, 2.4 at the back (43cm length).
-S-bend stays, full length housing/hose for the brake and derailleur.
Edit: I’m always pretty conservative about tire clearance. Here’s a picture from Minh of an Ikon 2.2 with the sliders all the way forward.
