Rigid 26 fork hunt

Hi!

I've got this On One 456 that I'm keen to build up into a rigid XC type thing. I'd first laid my eyes on a couple of Surly fork options, being sturdy steel and having mounting points. My main inspo was this pic from the internet, using a Surly Karmpus fork. Since then, I've built up this Marin for commuting and light MTB, which has now made me keen to build the 456 into something lighter and more fun.

The Surly forks are 1200g, whereas a carbon alternative could be half of that. Keen to find something that has mounting points, so I could run double bottle cages up front while still rocking a frame bag for potential bikepacking. What I need is:

• Carbon fork
  
• 475-490 axle to crown
  
• 100 front hub spacing
  
• Disc brake
  
• Straight steerer
  
  

If anyone has advice or ideas, please share. If anyone thinks I'm being silly and should just go for the Surly forks, then please tell me so.

Thanks a lot! Amazing resource and a lot of forks, but still none that fits my requirements. 🥲

Carbon
Load bearing eyelets
Straight steerer
Long a2c

I'd say that choosing just two things from that list is going to narrow the range of forks right down, make it three things and there's probably three forks in the world that'll suit.

The Surly fork is the right option.

I think a frame like this deserves a steel fork but.... How about this?

A-c 490:

If you look for 27.5 or 29" forks the a-c is what you're looking for because the 456 is designed for long travel forks.
You have to give up on the mounting points.

Thanks a lot for the help both! The choice is definitely between keeping weight down (carbon) or the potential to load it up (steel). Might end up with steel, I like carrying shit.

Salsa firestarter cromo is a rigid steel option which is 200g lighter than the surly

Many carbon forks with mounts actually have a very low rated carry weight

Absolutely gorgeous, I think we have a winner! Thanks a lot mate
