Sideshow – I have the 2016 E29 in large with 175mm cranks and have fitted the 650b yoke – lowering the BB noticeably.
I’m only getting the odd pedal strike, but the very low BB on my other bike has probably trained me to keep the pedals up through rocks.
The standard Fox DPS shock on mine holds the bike up very well indeed and it pedals great, but with the opposite trade-off to you that it can feel unsettled on rough terrain.
You pay your money and take your choice I guess. I’d like to try it with a twin-tube shock.
