Post by: That Swan Guy on April 01, 2014, 08:03 PM: Threaded both sides of hub with 2 different thread sizes, different size free wheels fitted and you can flip then around to change gearing.

Ok cool (but why would you want to do that on a bmx ) if i wanted to change a gear i'd buy a road or mountain bike ???

Post by: snoopy72 on April 01, 2014, 08:16 PM: I have a flip flop Suzue hub on the rear of my supergoose, I thought you flip the wheel around so you can make it a fixie.

Post by: glenboy on April 01, 2014, 08:22 PM: To my understanding you had the flip flop hub so you could change the gearing instantly just by flipping the wheel so you might have a 14 tooth on one side and la 16 tooth on the other so if you wanted a lower gear at a certain track etc it was. a 1 min job to change the gearing

Post by: dinglem on April 01, 2014, 09:34 PM: The rims that came with my Brum WHEELS were laced to Suzue hubs with a flip flop rear, and I am assuming they were original to the build. No idea on specific dates though.

Post by: Jaan on April 01, 2014, 10:04 PM: Yep, been around since the 70's and were specifically designed for race :daumenhoch:

Post by: Spen69 on April 02, 2014, 12:51 AM: Callum, as folks have said already, they usually had a 15 or 14T frrewheel on them to swap at a track by just turning the wheel round. The smaller side is a metric M30 thread and you can now fit down to a 13T freewheel on them (Odyssey make one) so you can run a 36/35 front like my race RetroGoose has :daumenhoch:

Post by: MartyC on April 02, 2014, 12:29 PM: BMX Flip flop hubs have been around since the mid 70s, Suntour and Shimano made them among others, they have been on track bikes way before then.
Title: Re: What's a ?
Post by: meticulous on April 02, 2014, 07:05 PM: weren't flip flop hubs a flop, complete waste of time, I have yet to see a bike with 2 cogs on the rear hub so you could whizz it round. Don't know why they sold, they look shite as well on a pony, just my opinion anyhow.... :coolsmiley:
Title: Re: What's a ?
Post by: BENDYCAT ELEVENTEEN on April 07, 2014, 10:57 PM: Add a double cog freewheel and then it get interesting lol

Post by: nosepickben on April 08, 2014, 10:11 PM: Bikes with 2 free wheels on were indeed a rare sight. I'm going to stick a pair on to on of my flip flopped wheels right now. :2gunsfiring_v1:
