MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
Currently got the bomber Z2 forks on my orbea rise e-bike with 140mm travel.
Thinking of getting an air chamber to make forks 150mm travel. Has anyone on here
done this or is it not worth it? cheers.
Seems to be common to run the Rise with 150 (stock option on many models) or 160 on the front.
My Fox 34 Rhythm 29" (basically a Z2 but with a Grip damper) originally came as 150mm. I'm not a heavy or aggressive rider but I definitly noticed flex. I've since reduced them to 140 and they do feel stiffer.
With the extra weight of an e-bike, I'd recommend against going 150mm.
The M20 Rise with the Fox 34 comes with 140mm travel same as H30 with the Z2 this gives a low BB of 336mm, if your getting lots of pedal strikes 10mm to 150mm would help, I swapped out my Fox 34 to my Manitou Mezzer I already had at 160mm
Either way, whilst you've got the fork apart you'll want to add some foams rings near the dust seals. Might help reduce stiction a bit, can only help.
For some reason Fox don't ship them with foam rings installed.
