    Fantom FB4 Comp

    Just got a motobecane Fantom FB4 Comp that didn't come with a front fork but everything else. Does anyone have measurements off what the fork was? Like the rake and spacings? New to this do need help. Thanks

    I assume you got it off bikeisland? It looks to be a 135QR spaced axle, with straight 1 1/8" steer tube. Brake mount is front hub offset.

    Similar fork to stock. Sun Cycle Warehouse looks to be the amazon storefront for bikesdirect/bikeisland, so these should be the same/similar.

    An alternative is the salsa enabler fork. It's what I use on my boris (coincidentally, also bought without a fork). The higher quality steel and design is nice, but it uses a rear offset brake spacing. Easy fix by swapping some of the axle lockdown nuts, but you have to be comfortable taking the hub apart. Easy to do, just be careful about putting it back together.

    Yes it was from bikeisland. That first link you sent me was handlebars and not a fork. Thanks

    Sorry, my copy/paste kung fu is lacking today. If you look at the other stuff Sun cycle sells, you'll notice a lot of it is very familiar.

    Functionally, I think they're about the same. Color difference. The one with the flare at the top of the crown looks a little better with a bike that has a zero stack headset (Boris), and the one without the flare was for the external bearing cup headset (Gravity bullseye monster).

    Since you have to get a new fork, I'd take it as an opportunity to upgrade to something better though. Carbon fiber, surly or salsa fatbike forks. There's some detailed information about using a carbon fiber fatbike fork on the MTBR Boris thread. Fork and lower headset cup.

    Is there a detailed walk through? I don't know the first thing about that.
