V20 with disc brakes

Freyot · Saturday at 10:50 AM

Hello,
I purchased a second hand Vendetta V20, it's probably from 2015.
I'd like to put my nice carbon wheels on it, frame having dropouts for disc calipers (IS standart)
However, as you can see on photos below, the centerlock screw touch the frame avec the disc is really really close to the frame, almost touching also.
Is there a solution or something I missed ? The axle of the wheel is well 100mm.
Disc is 160mm.

Thanks for help
Fred

People have filed off just enough to prevent rubbing. But since you report “almost touching” I’d leave well enough alone.

Hi Fred,

Have you considered a slimmer center lock screw? That might solve your problem since the current one is almost touching, this one pictured should do the trick.

In this case “a miss is as good as a mile”. Almost touching isn’t anything worth worrying about. If the wheel is secure in the dropout it’s not going to move laterally.

As noted, if it really bugs you get a new, thinner lock ring.

I have a Vendetta from around 2010 and I had to file the frame weld and can still barely fit a 140mm disc but it works.

I had the same issue with the 2015 model, the disk brakes that I had at the time were fitted via the six bolt config which would rub on the weld. As other have stated I filed the weld down by 1-1.5mm, only enough of course to clear the bolt heads. That bike I then sold and i believe has been sold again so is still going strong!

Looking at the pics again I'd agree with the above and should solve your problem. IME you have two types of lockring, one with internal splines that you tighten with the same tool that you use to install a cassette. And the other with external notches that you need to use a BB tool to fit. Yours looks to be the latter, as VMI suggest look at getting the lockring with internal splines.
