I will be using 25" spinergy LX wheels on a TR3 (1" rear wheel spacing). But i'll need to swap on a set of 24" LX wheels with knobbies and therefore need longer axles with spacers. I want to space those wheels out about 1/2" on each side. So where can I buy axles that are 1/2" longer than the ones used for Spinergy's 1.87" hubs on the LX? I've seen on Sportaid that there is an option for axles that fit Spinergy wide hubs (2.3"). Would that work? Any other suggestions?
