Ok, I know this has been done before, but I didn’t find a recent thread.

I want to replace the forks on my cross bike to some disc only ones, but I’ve got a straight 1 1/8″ steerer.

Most of the stuff I can find is either heavy (>600g), or for tapered steerer. I can’t find any light forks (~500g) with a disc mount for straight steerer, not even silly money ones.

So, anyone know of anything, and if not, got any experience of the Kinesis DC37 which seems about my best option at the moment (still lighter than my current forks)

I looked a while ago and found the same story.

I think lightweight disc forks have bypassed 1 1/8″ innit.

Ah – I was gonna suggest the DC37. I have the (earlier) DC19 on my cross/tourer and it has been sound.

I just found this:

somehow didn’t find it when I spent ages looking last night. A bit too much money, but it’s the right thing. However, it’s only 30-40g lighter than the Kinesis, and double the cost.

Thing is, on-one were very forward thinking, so I have a nice Titanium cross bike set up for disks. Seems a shame to get rid of it.

actually, 405mm could be a bit long.

this is what I have right now, and they’re pretty good, but overall my bike is a bit heavy since I disc’d it up.

This is a subject I know nothing about but I have some Cotic Carbon forks on my roadrat with discs. No idea on weight but maybe worth giving them a shout? If this proves pointless information then apologies but hope you find what you need 🙂

Too long/too heavy?

Trigon are the only full carbon disc fork in 1 1/8 that I know of. I have some, same as Leons link, but I’m pretty sure they came in lighter than 595g… can’t recall exactly how much but 550ish rings a bell…

That On One fork is too long. You need <405mm C2A really.

I guess you won’t find many as disk brakes + narrow carbon steerers tend towards being flexy and give brake judder.

These ones are real nice:

Tim@ Sideways does the Spot ones they look very nice……… Must resist 😳

Thorn?

HERE

Got the Spot forks on my Salsa Vaya. Highly recommended. See my review on their site.

Some good options there – I might call about the Thorn ones, although I note they talk about “Trekking”. If Trekking means hammering down rocky descents on 32mm tyres, then I’m good to go 🙂

Spot ones look very nice too. According to here:

UNDER 500g!!!!!
