Length is slightly different, which is why i sue to make them in my previous job If the new wheel is the older type and used as a spare wheel I would suggest getting a Spacer made, then you will require different spacers on the spindle. You could try using the later style spacer but don't complain if the wheel moves off centre while your riding, just ask Andy Shepard about that one Checkout the Desmo Due Paddock on Facebook |
