Hello I have bought a whyte t129s I’ve rode it a few times and have noticed some chips in the paintwork from the stones that fly up is there anything I can do to stop this happening

Try to avoid riding it near stones. Indoors, maybe.

Battle scars.
Relish them.

(or quit mountain biking)

Put it away , then advertise it on the classifieds

Damaged goods.
Give you fifty quid for it.
(if it’s a Large)

£65 ?( again, if its a large)

Depending on where the chips are, you could try one of these:

RockGuardz

Highly Amused at all the replies :D, but let’s take pity on the poor OP (Belly). I’ve got some tough clear plastic stuck on the down tube and various strategic bits of my Flux. Can’t remember what brand it is, but I got it from Ride Bikes in Parkstone Poole. Why not google them and call them up?
Alternatively you could throw away your Whyte and get a titanium Salsa Elmariachi 😉

Helicopter tape. Clear and tough. Not all that cheap anymore but it’ll do exactly what you want.
