I’ve noticed that my Rise M20 has developed a bit of a front wheel vibration under braking. I have only ridden the Rise on some very easy bike rails, nothing that would have over taxed the frame or fork.

It’s a new bike that I had my LBS put together so I don’t think there is any issue with assembly.

Any insights would be appreciated.

Possible glazed pads? Pull the pads - check their condition

Are your rotors vented? I have had a pulse feeling with vented rotors (holes in brake track) where I think it was the leading edge of the pad "catching" the vent holes. I minimized it by sanding a chamfer on the leading edge of the brake pad as well as chamfering each hole on the brake track.

First clean your rotor with brake cleaner and de-glaze pads. And check that rotor is straight.

Post a photo of the brake setup, it will show if it's been assembled properly.

I've seen photos of incorrectly installed brakes that were done by a bike shop.

My Trance-E came with the same brakes and had the same vibrations on the front brake.
Switched to full sinter pads and the virbration became less, but it's still there.
I think it's the rotor. The first generation of TRP rotors were even worse. I had those too.
Replacing the rotors fixed the problem for me.
I'm not saying that the design of the rotors is at fault, but maybe a manufacturing qc issue were the rotor is not made evenly around the surface. A friend of mine had Magura SL rotors that were also terrible with noise and vibrations.
Same story, nothing helped except replacing the rotors.

Thanks all for the feedback.

It doesn’t particularly bother nor does it seem to cause any braking issues other than those described but I just don’t want the front brakes to suddenly stop working or have a some sort of wheel issue.

I’ll have to take it into the shop

...but I just don’t want the front brakes to suddenly stop working...

Roger that

This literally just happened to me and I found out my headset was slightly loose. I couldn't tell the headset was loose any other way but it definitely caused the front brake to be shuddery.
