Carbon gravel fork with… straight alu steerer, 15mm axle, post mount…

And 45mm tyre clearance please. Plus cargo mounts on the legs.

Does this exist?

I thought I’d hit jackpot with the below, but probably gone for good.

I’d take an IS disc mount instead of post mount, not that that changes anything. Or a flat mount that will take a 180mm rotor, which probably doesn’t help either.

Yes, I do want an aluminium steerer.

Actually, 12mm axle is OK, or even quick release if something ticked all the other boxes.

Have you seen this list?

Complete List of Forks with Bottle Cage Mounts (Utility Forks)

I’ve done an amount of fork browsing and not seen much of anything in the way of aluminium steerers

Now on a steel fork to get the spacers i needed

Thanks @Onzadog, but yes I’ve had a look through that already I’m afraid.

The closest thing on there is the IRD MCX, which I actually had on another bike I sold a year or so back (damnit)

The only issue with it is flat mount, which is potentially a bit dodgy with a 180mm rotor. Could be fine though, so that’s my backup plan

Ah, so maybe flat mount will be fine

Crust do one that meets most of your criteria but I think is a carbon steerer. No idea about importing one either.

There’s quite a few options (that you don’t even have to bother with the faff of importing) if you ignore the only thing that they’ve been particularly firm about.

Why do you need an aluminium steerer?

Why do you need an aluminium steerer?

Because I’ve been cursed with loosening headset issues for many years — different bikes, different stems, different headsets. My current setups seem to be holding up OK, but only at torques beyond what a carbon steerer can take, and with an additional headset locking spacer (which also wouldn’t play nice with a carbon steerer). So I’d rather not have a set of forks I need to be delicate about.

Surely a deep carbon bung and carbon grip tape will be sufficient to get initial tightness in the stack and then prevent movement from the stem?

Across 8 bikes, only one doesn’t have a carbon steerer and of those, only the commuter has come loose and when I checked that (after 35k km) the stem bolts weren’t as tight as they should have been.

@Daffy, you would expect so, yes, but history tells me I do not have good luck with these things. Most recently, I was having problems with my hardtail, got my lbs to install a new Hope headset and check the headtube wasn’t ovalised, but it still came loose the very next ride. I had to swap out my ti stem bolts for steel and (over)torque it to 10 nm for it to hold.

In any case, the stem on my gravel bike isn’t compatible with carbon steerers (and I don’t have another of the right size laying around), plus I’m not sure I have the tools to cut down carbon. So it would just end up adding quite a bit to my budget.

close? 12mm and does seem to have a single cargo mount (full bike version says cargo mount)

There’s exactly what you’re after here. It’s a lot of money – I bet you can get a carbon fork, a carbon hacksaw blade and a new stem for less.

Why is the flat mount an issue? I’ve been using a whisky MCX with flat mount caliper and 180mm rotor for the last two years and no bother. Also on my vagabond with a 160-180mm adapter and flat mount cable calipers. My holy grail is for a rigid 29er fork with 100/12 axle, mudguard mounts and straight steerer…

@munrobiker, yes, that’s perfect! But unfortunately it is the one in my original post and out of stock and no longer made

@akeys001, thanks, yes those are one I’ve also considered, the only concern is that I’m not sure they have much clearance, it’s hard to find out for sure but the profile looks fit for perhaps only a 40mm or so(?)

Something here – https://www.fyxation.com/products/carbon-fiber-adventure-fork although I’ve never heard of the company before.

The specs. list a straight steerer option but this doesn’t seem available to buy, so possibly out of stock. Might be worth getting in touch though if it looks suitable.

— Edit —

Sorry, just spotted that it’s not approved for 180mm rotors! ☹

Thanks @PJay, I am also considering them actually, they are meant to be decent. My main worry was actually clearance, which at 43mm is a little lacking.

It looks like I’ll have to either go for the relatively expensive IRD MCX below, or be less fussy about steerers.

Alpkit/Sonder are selling off brand new carbon Camino forks for £60 on eBay. Carbon steerer and a 12mm axle, but loads of tyre clearance – 50mm tyres at least and accessory mounting bolt hole things. They’re colour matched to the frames, but if you can live with that, it seems like a pretty good deal and you could always let fly with a spray can,
