woody Posted January 16, 2015 Report Share Posted January 16, 2015 (edited) Which model? Which wheel? There are different hubs fitted to early and later models. This is what I THINK Later type front wheel crosses three times Early front wheel crosses three times Rear wheels cross twice Early front Later front Edited January 16, 2015 by woody 1 Quote Link to comment Share on other sites More sharing options...

stevem75 Posted January 17, 2015 Report Share Posted January 17, 2015 One thing that threw me off the first time I rebuilt a Bultaco sherpa wheel was that the inner spokes all go the same direction. And the outers the opposite direction (cross two or three). This type of design is not used on modern wheels and as a professional motorcycle mechanic I only had experience on the new stuff. Not sure why akront or Bultaco for that matter built the wheels that way. Anyways check to make sure you've got it laced that way.

midlife Posted January 17, 2015 Author Report Share Posted January 17, 2015 Its a 198. The long spokes are to long and have to much of a bend to do a 2 cross patern. The original spoke patern is as above. Quote Link to comment Share on other sites More sharing options...
ask greeves Posted January 17, 2015 Report Share Posted January 17, 2015 While on the subject of wheel building, does anybody know what years Bultaco used aluminum nipples on Sherpa and wether they were used on both front and rear. Quote Link to comment Share on other sites More sharing options...

The 198 spoke set - ie: for the later front wheel - from In Motion fits the later wheel correctly as I've used them, so have you definitely got the correct set. Just measure the spokes you have and check the length with them Quote Link to comment Share on other sites More sharing options...
lbhbul Posted January 17, 2015 Report Share Posted January 17, 2015 (edited) Greeves To help answer your question; checked for ally nipples as follows; m49, m92, m199, 199a, would guess more but these were at hand. Don't know what after market might be, probably some sort of 400 series stainless (magnetic). Original spokes non magnetic.(mine anyway) Hope this helps.

bondy Posted January 17, 2015 Report Share Posted January 17, 2015 just got new spokes from inmotion for my next build 1 Quote Link to comment Share on other sites More sharing options...
bullylover Posted January 18, 2015 Report Share Posted January 18, 2015 Hi Midlife. I have had the spokes bend before on a Pursang wheel I was respoking and I was told I had the rim on the wrong way around. So flip the rim over and it will work out okay. It helps when you strip a rim to mark which side goes where as in sprocket side on the back and brake side on the front. I hope this helps.

lorenzo Posted January 19, 2015 Report Share Posted January 19, 2015 (edited) Just finished lacing wheel 3 cross long side 2 cross short side Just a true up,i think it will be ok :banana: Don't wanna give you banana skins to slip on, but you sure ? - doesn't sound right to me....... 198 std. front wheel is spoked to a " X3" pattern, i.e. each outer spoke crosses over three inner spokes on the same side of the hub. This applies to both left and right sides of the wheel - long and short spokes alike. As in Woody's second image... Not sure about pattern spokes, but OEM Bultaco spokes came as 18 long spokes (inner and outer) left , 9 short spokes (inner) & 9 short spokes (outer) right , meaning different lengths, by the way.
