Anyone have one of these and could please advise on clearance on Conti GP4k 28mm on a 17mm or bigger internal width rim?

Seems a bit of a lottery these days and would be good to know what I can run before buying. Columbus info says up to 28mm but that could mean 28mm on a 15mm rim...

Axle to crown is 368mm but not sure that's enough!

Thanks

I have that fork. Here’s a couple of pictures if it helps. Tyres are Schwalbe 1 and measure 25.5. The rims are Open Pro - 20mm outside and I think they are 15 inside. So, some help but sorry I don’t have wider rims that will fit that bike.

I'm left handed, if that matters.

Hey thanks for replying! 👍
Looks a little tight in there but could use some additional info from someone who’s running wider rims.

Well I bought one so I can now answer my own question!

Yes, it fits with about 3mm all round between fork and tyre, which is pretty acceptable I think. Haven't tried for brake clearance but I don't anticipate any issues with the brakes I'm using currently.

Will try to get a photo uploaded as evidence.
