Front drop out adjuster/ insert?

[HLaB]

Hi,

My wide rimmed aero wheel is a very tight fit in a tt frame, if it sits at the top of the drop out, it rubs; if it sits a mm or two lower its fine. A problem occurs though if the skewer when riding rises to the top of the dropouts. Is it a case of just ensuring the qr is tight enough or do you get some sort of insert/adjuster which stops the skewer doing this (rising a few mm) ?

TIA

My understanding is the front wheel should be fully pushed into the drop out.

If it rubs elsewhere then the wheel is not suitable for the frame.

Cheers,

I'm running pro 4 Service Course 23mm, I may try a different brand or a 22mm conti attack and gain the mm that way or resign my self to a new rim in the new year.

Wot he said.

axl to the top of the Drop out so the fork takes the weight, not the spindle. Spindles are just there to hold the axle in, not weight bearing, which if you try and hold it on the QR you are doing - and damaging the DO the 1 / 2 mm down.

You may eb able to get stops that sit indie the DO, but realistically if your wheels too big, its too big. New fork or new rim.

Just out of interst, how does the back one fit/

I used to run a 25mm on that wheel (the rear) on another bike but had to change it to a 23mm to fit the TT bike but after I did so, it fitted fine.

I know TT frames are designed for tight clearances, but I find your experience disappointing.

If a TT wheel and tyre fits the back, you are entitled to expect its matched twin to fit the front.

How old is the bike?

If it's fairly new, I would have a friendly word with the supplier.

I don't think you are entitled to anything from the warranty, but as a matter of goodwill they might help you out a bit with the cost of a front rim.

Can't see how a new rim will help, unless you go from 700c to 650. A smaller tyre is the smart thing.

Its a second hand one I was testing but I've opted against buying it. It works well with other traditional width wheels just not my 23mm wide front wheel.

My rims are 23mm wide and traditional rims are 19mm but a new tyre is a cheaper option

So where on the wheel/tyre is it hitting the frame? Sides of the tyre or the tread? Or elsewhere?

Side of the tyre at the top. I think the Mitch pro 4's Im using come up big too, so I may get lucky with a different brand :-/

Makes more sense to me now.

If you consider buying another TT frame/bike, you will now have a better idea of what to look for.

I had the same issue with a Ridley Oval track frame. Had to run 19mm on the front as the clearance was so tight. Cheapest option, bike was still sweet!

A wired 23mm kenda fits better than the 23mm mitch Pro 4, I think a 22 mm conti attack or similar will work so I've sent an email to the wheel manufacturer as to what they'd safely recommend.
