I picked up a 2019 Jeffsy 29 CF PRO RACE & trying to decide if I should keep the 150 fork it comes with or replace with a 160 fork especially since I already own a 160? I have read other posts where it seems like folks are happy with the 160, and I like the idea of the 160 fork for the bigger travel and raising the BB a bit.

However, the 160 I currently own has a rake of 51mm & I noticed the stock 150 fork is 44mm. I understand the basic concept of what the rake is measuring, but what I don't totally understand is how this will really change the feel of how the bike feels and handles, especially if I were to increase the travel another 10mm.

Does anybody have any thoughts / recommendations / insight that they could share that may help me decide which setup to run? Thanks!

The Jeffsy was probably designed around a 44mm fork offset. Some models come with 42mm offset/46mm offset Rockshox forks but that’s only a 2+/- difference. A larger offset will decrease tire contact and could cause your bike to feel squirly during turns. I’d try to stick with a offset closer to what the bikes are specd with as the frame was designed around that.

That being said, a larger offset shouldn’t affect the integrity of the bike so you could get away with running it.

How has running the 160 mm fork been? I’m wanting to up my 29” cf pro from 140> 160 but don’t know if it’ll mess the bike up too much. Thanks

You can run as much travel as you’d like. However, I’ve heard YT only recommends a maximum of 150 front/rear for the jeffsy 29er. Increasing travel beyond that could put excess stress on the headtube and void warranty.

Ok cool. Yeah I’ve been told that by them.
Might just push to 150mm.

How has the 160 Been for you? Big change in how the bike fees?
