stichillist Posted March 2, 2010 Report Share Posted March 2, 2010 I am going to attempt the rebuilding of both wheels on my 199A with relined hubs and new stainless spokes. Can anyone help me with measurements for the offset to the rear wheel? I thought i had measured accurately but now not so sure. Quote Link to comment Share on other sites More sharing options...
scrappington Posted March 3, 2010 Report Share Posted March 3, 2010 HI been building wheels or years. to check the offset remove the tyre put a straight edge on the brake side (where the drum fits in) long enough to reach the rim. Then measure the gap between the straight edge and the rim this is the offset distance. This is only correct if the wheel HAS the original offset. make sure the wheel looks central and even both sides of the forks/swinging arm.

I never use stainless spokes on a competition bike, always plated steel. Stainless spokes are too brittle and only for old road bikes or bikes for showing! PM me and I'll measure up one of my original wheels, front and rear for you! Big John Quote Link to comment Share on other sites More sharing options...

bultaco49 Posted March 4, 2010 Report Share Posted March 4, 2010 In the spirit of these forums being a place where occasionally one can disagree with knowlegable and respected members of the forum I'd like to challenge the 'no stainless steel spokes for trials' theory. I'd make the bold claim that good quality modern high tensile stainless steel spokes are perfectly suitable for trials use. Of course, I'd also recommend that whenever buying spokes only buy from a reputable spoke maker or supplier who can give proper advice and recomendations on spokes and nipples. The worst ill-fitting and poor quality (galvanised) spokes I ever purchased came from a very respected parts supplier. I learned my lesson and now only purchase from specialists. They supplied as original single butted stainless steel sets to my specification made up from from wire developed for motocross. They have performed very well for the past three years they have been fitted and have the bonus of looking very smart. I have never heard of or found an incidence via the web of a wheel breaking up due to stainless steel spokes breaking up. On the subject of the offset for the 199a. Whenever I rebuild a wheel I set it into the frame, make sure front and rear sprockets align then adjust the offset to clear the exhaust one side and the chainguard the other. Its a bit tight on a Bultaco! When the offset is ok I remove the wheel, set it up on a spindle between two car axle stands and tension the spokes and adjust for ecentric and lateral movement.

woody Posted March 4, 2010 Report Share Posted March 4, 2010 From my own experience, I've never had a problem with stainless spokes. All wheels I've ever had rebuilt with new spokes have been stainless. The oldest set were done in about 1993 by Central Wheel on an Ossa and that bike has taken a real beating over the years but I've never had to even retension one spoke. I've definitely never broken one (we all know what's going to happen now though, don't we....) Aren't Ossa and some Bultaco spokes stainless as standard fitment?

I had to replace all the spokes (in one direction ) on my Bultaco on the sprocket side. Reason I was give for galvanised over stainless was gal' has a bit of "give" quote George Spence.

I am not saying stainless spokes are rubbish, but the chap I get all my wheels built with is none other than George Spence, the finest wheel-builder in Scotland and a former racing motorcyclist. He recommends no stainless for comp use! That'll do for me! Big John Quote Link to comment Share on other sites More sharing options...
