Hi everyone

I have the fuel EX 5 2021 still with standard rims and hubs and was wanting to put some hope hubs on to match my new hope brakes however I’m not sure which to get or how I would find out. Can anyone help please??

thanks

Based on the frame and fork specs listed here:-


You require a Boost (110x15mm) thru axle front hub. For the rear you need a Boost (148x12mm) thru axle hub. 😉

Edit: Like @006_007 says, with a Microspline freehub.

Looks like your trek has boost hubs front and rear with 6 bolt rotors.

Rear appears to have the Shimano microspline driver.

I assume you would be upgrading the entire wheelset - not just new hubs on the existing rims?

I’m not sure to be honest. I love riding but am new to customising. I’ve been told hope hubs are a good upgrade and visually will looks good next to the brakes. What else along with the hubs would I need?? Just rims or rear cogs etc too?
