Looking for a 100mm 15mm fork that fits a 29x3.0 tire

[cetuximab]

I bought a used 29 plus frame.
The seller included a fork that is not a 29 plus fork. It will not fit a 29x3.0 tire.

The crappy think is, I a bought a front wheel to fit a 15x100 axle. So, I have a front wheel with the wrong hub.

Does anybody make a 29 plus fork with 100mm spacing.

All the forks I found are boost spacing - 110mm.

Any 29 plus forks I should look into with 100 mm spacing? Or would I be better off buying a boost fork, reselling the wrong fork. Buy a 110mm hub and have the wheel rebuilt.

Rigid or Suspension?

If rigid, then the carbon fork that came on the Trek Stache 5 will work (don't get the 1120 fork, that's 110 spaced), an older Niner Carbon should work, and the Salsa Cromoto Grande Steel or Surly KM will work, as will plenty of other steel off the shelf or custom options.

If suspension, the fix is a little more complicated. Fox Float 32 or 34 for 29" is the fork with the most clearance in a 15x100 TA flavor. Still not sure you can fit a true 3" tire like a Knard or the Chronicle that's in your picture.

Other workarounds would be trying a 2.8" or 2.6" tire. Also, someone (mtbtools.com, maybe?) makes little adapters that will convert a 15x100mm hub to 15x110mm. They are a little bit fiddly, and you also have to space the rotor properly. Maybe some stuff I haven't thought of on the mtbr.com plus-bikes forum.

Good luck!

You're going to have to least get a boost fork if you want to run a tire that big. The adapter route is not all that great and front hubs are cheap. Build your bike around fork and application, not the other way around

It's gotten to the point where most modern mtb setups are boost. Bikes are changing pretty quickly, if you've been on the same rig for the last 3 to 4 years and shopping today you're going to feel like rip van Winkle...in a good way. Modern technology really does make the MTB experience more enjoyable. From the way parts work to how you sit in (not on) the bike. Physics works

Will a Salsa Firestarter work for you?

I got a boost hub for $70.
I'll sell the non boost hub and find an inexpensive rigid fork.

Thanks for the sound advice.

Thanks for your time and response.

I really want the plus size tires to fit.

After seeing the tire not fit in the standard 29 fork. I am gunshy buying one of the above mentioned forks. I'll try out the mtbr plus forum.

Thanks again

Add the MRP Rock Solid to your list. 3.625” between the fork legs.

Salsa Cutthroat Fork

Surely, there are some steel options from Surly as well

If you can find the trek stache 5 fork, it was designed with 3.0 in mind. And I can personally confirm that a 3.0 fits in the salsa steel fork. Firestarter is a good option too- also designed for 3.0 on the old dropbar Deadwood.

That said, if you've got a hub ready to go, then maybe just rebuild the wheel and not have to mess with a non-optimal situation.

Salsa and Surly both have forks that get wider at the top.

My local co op has a surly one, but it's QR rather than 15mm.

Thanks everyone for some great suggestions.

There is a Bontrager Bowie I'll bid on eBay. If I lose that auction, I will likely rebuild the front wheel with a boost hub.

There are several Rock Solid forks in the $400 range.

Thanks for your time and suggestions.

I think Jeff Jones is making a steel fork...not sure if it will work for your application, though...

For rigid, my Whisky 9 fork fits a true 29x3.0.
