I need to learn more about building wheels. As in , replacing 19" "MX" rims with 18" rims for offroad use... the initial problem is, finding the hubs. Yup, Talons are $450./retail. But they aren't readily available for non-current (older model) bikes. You know, the ones that NEED them. Either due to wear,or damage, the older bikes are in need. Yes, the fast guys trash 'em on late model bikes, but the older ones are where there is a demand. So , where can I find them ? The parts warehouses have "complete" wheels , and rim/spoke sets listed, but what if one wants to change the rim size , on the OEM hub ? If I already have it apart, I may as well replace the hub with a nifty aftermarket unit, right ? Does anyone offer the hubs seperately ? That's the missing link ... I'm trying to change a Y2K RM250 from 19" to 18", and I've already bought a rim/spoke set. Hubs fit '96-'00, and then '01-?...I'm working(shopping) the Ebay thing also ... thanx for the assist ! GasGas comes with 18" rims on the rear ...
