I'd second that. In CNX there is a "wheel soi" which is down Chiang Moi Rd to where the small klong is and on the right - Sithiwong Rd on a map with a big travel agency on the corner. It's one way and you're not supposed to enter from Chiang Moi but T.I.T.penetrator wrote: Aluminum rims are very cheap in Thailand but not sure if you can get 18", seen plenty of 17" around for about 500-800 baht a pair. I've got an old Honda Cub I bought for £50 that has badly rusted and pitted rims, thinking about bringing the wheels or hubs over in my luggage and getting them rebuilt.
What I'd do is check out prices to get aluminium rims laced to your hubs with new spokes (pref stainless), then before buying, walk back up the road to "Preeda" (a.k.a. "The Chinaman") to check availability of half-decent sticky tyres as tyre availability will probably influence your choice of rim size. Once that is sorted, get out your birthday pressie angle grinder and buzz through the spokes to free up the hubs. Give them a clean up and take them to the wheel soi to get them laced up to new rims.
Cheers,
Pikey.
