Trek domane tyre

[Jekpoint]

Hi

I have a trek domane 2.3, and I have changed the rear tyre to 28 (it was 25 originally)

The tyre rubs with the brake arm (v brake), I fear it doesn’t seem to be compatible

Is there any way to adjust the position of the brake arm? I just need it to ne around 2mm higher

Thanks

pics would be nice, did not know they had v-brakes, i was thinking it had calipers. very few road bikes today can handle a 28c tire.

Agree with what Painkiller stated (but nothing that the "reap" fool says). I do not know if your bike has vertical or horizontal drop-outs (I assume vertical or thru-axle); but on my bikes I can adjust the rear hub position to allow for tires that are not necessarily meant to be installed on some of my frames to avoid tire contact with the brakes. I think 28mm is pushing it but if the frame can handle that size then go for it. I thought those models (at least early models) had caliper brakes so I will admit to not knowing your bike's configuration. What year is your model?

Bikes in yesteryear could rarely fit a 28c tire. The pro scene has begun adopting larger tires recently for the comfort and safety of them. Sizes like 28c has become a standard and 32c behind it even. With that, modern bike components have also began to adapt for larger tires. Shimano would normally only fit 25c at most, but now 28c is a standard for Shimano calipers.

As for your v-brakes, there's a nut that locks the brake pad into place. See if you can loosen that nut and then shimmy the pad down flush with the rim and refasten the brake pad.
