Hi All.

I have got hold of a GasGas rim and want to have it laced onto my 200 hub.

Anyone know of a wheel builder in the Southwest UK? Also anyone done this and have an idea of the type of spokes i require?

Ta.

Steve

what year rim is it?

Slgihtly off the topic (but not much) I want to do the same with a ty175 hub has anyone done that and know how or where to go to get it done,

Thanks

Up North you want to speak to Birketts, a mate just had a pinky hub laced to one.

You need to get a rim which has 36 spoke holes

all modern trials bikes from about 95/95/97 on have 32

Hi there.

It is from a 93, it has 36 spokes.

I presume you are looking to do this as tubeless are better than tubed - is the difference significant

Well im not sure if my ridding ability justifies it however i am fead up with the tube tyre rotating during a trial and stressing the tube. It means breaking the bead and farting around with getting it back in position. It wll also mean i can use tubeless tyres and have them fit better.

I have a 74 TY Yamaha with a tubeless rim on the rear, used a Fantic rim, laced with stock length spokes, works great don't have to worry about pinching tubes. Fantic and Gas Gas TXT's had 36 spoke holes maybe some of the Sherco's, have bought rims off of ebay, going to lace in either a Gas Gas or Fantic rim onto another modified hub and its going onto my Tiger Cub.

Not to do with performance for me, rather the limited choice of tubed tyres now available, IRC and Michelin.

The IRC grips as well as anything but has been spoilt by the butter-like strength of the sidewalls, if you weigh over about 12 stone they roll around all over the place. Increase the pressure to over 5psi to stiffen it up and you lose grip. If you can put up with the rolling they're fine but at 17+ stone I can't and I'm sick of the bloody things. They puncture easily too.

The Michelin isn't a tubed version of the X11, I've no idea what it is but it's about as good as a racing slick on ice when used in a muddy trial. Didn't have one on long enough to try it on rocks. I'd bet a Pirelli MT43 is better....

Soft sidewalls apart. as regards performance in terms of grip between the IRC tubed and any tubeless tyres, if there is a difference, you'd have to be able to ride well enough to push the tubed tyre to its absolute limit and then be able to ride the same terrain with a tubeless and feel any difference. 95% of trials riders don't have to worry about that.

Main advantage of tubeless is wider choice, less chance of punctures, stiffer sidewalls.

Some tubed rims will seat a tubeless tyre with a tube fitted with no problem. Again there is a theory that the tubeless doesn't work as well with a tube in but if a rider can tell that they should be in WTC I reckon.
