Are MTB flip-flop hubs difficult to find and expensive? Been asking around Cartimar but couldn't find any--except BMX ones which I don't think will fit my MTB frame. Has anyone seen cheap generic flip-flop hubs anywhere in Metro Manila?
In case there's any other design that I don't know of, I'm talking of the threaded hubs with threads on both ends for 2 freewheels--one I could use for flats and another for climbs. Curious... is this the same hub as the ones used with a freewheel on one side and fixed-gear on the other?
Thanks.

Has anyone seen cheap generic flip-flop hubs anywhere in Metro Manila? I saw one at Tryon once, long time ago. When I went back, it was gone.

By the way, most flip-flop hubs are spaced for road/track bikes. They may not fit a regular MTB frame.

most flip flop hubs are used for bmx racing so that when you get to an unfamiliar track its easy for you to change your gears over. i havent seen any for mtb's though.

White Industries makes a flip flop hub... eccentric at that. This is the one I want to get to eliminate using a tensioner. I believe most flip flop hubs are fixed on one side. You don't need this type of hub for a 2 speed. There are less expensive solutions. Use a derailleur as a tensioner and put two chainrings on. Set the tensioner as tight as possible on the big ring for riding on the flats/road. When you get to the trail use your heel to drop the chain to the middle ring. You don't have to get off your bike and flip the wheel. Besides most mtb tires are unidirectional. www.whiteind.com/ENO_Products/eric.htmlhere's my tensionerless 2 speed. yes, I have to undo the quick release to change gears. if you have semi-vertical dropouts you'll have lots of options for gearing. this setup is 36X20, 42X13

Thanks bros. I'm actually still in planning stage. Since this will be my first SS in a long long time (since my childhood days) I'd like feel the much talked about serenity of SS riding without rattling of a derailleur on bumpy roads.
brad westcoastbo thanks for the recommendations but these White Ind stuff are considered pretty expensive over here--if I can even find any. Right now I'm looking at building an average "messenger" bike that's MTB based. You know... SS, steel, semi-slicks, etc.
Just thought I'd explore the possibility of flip-flops for MTB since cheap ones are available for BMX. If it's not feasible then I'll stick to a "compromise" gear combo.
For now, I'm considering using an old steel frame (hi-tensile from a mall bike) which has horizontal dropouts. Another possible option is maybe having a custom steel frame built--MTB geometry but using BMX drivetrain. Very flexible and readily available parts. I think custom-built frames here aren't expensive, specially if using hi-tensile tubesets.
