Ewwww.
As someone who failed at math so bad in school that I opted out of math as an elective altogether in year 12 I sometimes surprise myself.
The 27.5″ wheelset has obviously completely altered the Chisel’s geometry (not that I really care as the bike feels great to ride!), but curiosity and the savage -18mm bottom bracket height (more pedal strikes) on the smaller wheels got the better of me so I sought to correct it.
This geometry calculator made it easy for me to figure things out (it even lets me enter in the 51 fork offset of the current forks vs. 44 offset of my other forks).
With my 140mm Fox 36 SL fork from my Torrent hardtail replacing the 120mm SID the geometry is looking much more like a standard non EVO Chisel. The BB height is still lower, but I gain 5mm more height from putting the flip chip in the high position and also a few mm from the super fat tyres.
I’ve got the Fox 36 SL on now (easy swap thanks to split crown race on both forks). The orange is OTT (too much IMHO), the steerer tube is WAY too long too (will not cut until I’m sure) but the 36 is only 143g heavier than the SID which is surprising.
Keen to get out and test this setup some time this week!
