Newer Gen 4 carbon rails have a 1.8 lower, mine has the same
@bfletch2006 - if your existing fork is a zeb, you could leave the crown/steerer in place, and swap the internals and lowers of the new zeb ultimate onto it. And you can rebuild the leftovers into a 1.5 steerer fork which will be...
The EMTB hubs aren't that much different, I think swapping the freehub is probably all you need to do - only difference is the EMTB hub engages all 6 pawls at once (54 points), whereas the regular bub has them offset, so it's 3 engaged at a time (104pts). Easier/cheaper than a whole new hub and...
Have a few rides on the Vivid, not done much to it other than set sag, but main thing I've noticed is that I don't bottom out, and the bike feels that little bit calmer at speed in the rough, maybe a little plusher. All in al,. very happy with it so far.
Sort of... that 2.61 is an average - see the graph of leverage ratio from Rob's Rail review
By the time it hits 150mm, the progression in the frame design means leverage is roughly 2.4
So my extra 5mm of stroke is adding 2.4 *5.0 - about 12mm
I'll see your 230x60 and raise you 2.5...... this is a 230x62.5 on my large Gen 4
I know a 65 stroke will fit too, but I'm keeping it in the low setting, didn't want to overdo it.
