Just found out that the same fork offered on the new Stache 1120 will be sold through Trek as a stand-alone option. They are on backorder right now and go for $400.

Good news for older Stache frames or even other 29+ frames looking for a better carbon fork with extra mounts!

My main concern on this new model is how it compares to the current stock Stache fork in geometry. Is it taller, making the HA steeper? I do like all the mounting options, but would not prefer a longer fork. Tough to get actual fork numbers through Trek. :madman:

The 1120 has a new fork, the 1120 Adventure HCM Carbon.
Unlike the 2016 Trek Stache 5 that came with a rigid carbon Bontrager Bowie fork in the standard 100mm width, this new fork uses the BOOST 110mm spacing. All of the 2017 Trek Stache models came with suspension forks using the BOOST 110mm, no rigid forks were offered on any of their plus bikes.

The 1120 Adventure HCM Carbon fork allows for mounting of the proprietary front rack as well as accessory mounts that allow for bikepacking accessories such as the Widefoot Designs Liter Cage, Salsa Anything Cage, or Blackburn Outpost Cargo Cage. :thumbsup:

At 510 a-c I think this fork is spot on! Was also looking at the Niner boost RDO fork which is listed at 490 a-c. Looking to mount a rigid carbon fork to a 17 Stache frame, without changing the HA too much. I would also need to have rack mounts for bikepacking, so this HCM fork looks to be the answer!

For reference, here are the AC heights for several common forks. Note that these measurements are often consistent across multiple models of the same manufacturer, but check to be sure.

ROCKSHOX PIKE
120mm (27.5): 512mm AC
100mm (29+): 523mm AC
110mm (29+): 533mm AC

MANITOU MACHETE
120mm (27.5): 516mm AC
100mm (29): 510mm AC
120mm (29): 530mm AC

FOX 34
100mm (29): 517mm AC
120mm (29): 527mm AC
100mm (27.5+): 515mm AC
120mm (27.5+): 525mm AC

This fork looks taller to me than the standard carbon fork on the Stache. Maybe just an optical illusion or something. I guess a bit taller fork would slacken the HA but would also make the front wander some on steep climbs. Still a great fork for 4 bills!

Anyone else found a fork similar to this?^^

Like the fork at 510mm a/c. Also looking for a chiner carbon in 500 to 510mm for the Stache, but having a hard time finding one. Plus the 1120 fork is not currently in stock at my Trek dealer. Not really liking other options under 500mm a/c size.

We don't have them in stock at the east coast distribution center in Charcoal, but we have them in Trek Black. But your LBS can backorder one to have it arrive when in stock.

As for another option, I personally haven't seen another like this one out there.
 
Not to dig up an old thread, but I got my 1120 fork today, What fork race did you change to? It seems like the one off my pike is different.

Actually, they both measure 39.8, it just seems like the one on the pike was tapered and easy to set. The one on the stache is straight and a real tight fit. I might just need to man up.

Thanks!
