Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

SRAM Torpedo hub

Fixed or Single speed at the flip of a switch. Well, you spin a small screw at the center of the axis a few easy turns.

I am a happy owner of this bit of hard wear and I am wondering if I'm the only one who likes the ability to switch in a matter of seconds.

Its a pretty hardy unit but there is scarce information on the internet. It appears to be unsealed. In single mode it runs smooth, in fixed it has a small amount of play similar to a slightly slackened chain.

Not that it really matters but is this piece of technology deeply offensive to purists? Curious as to why Im all alone. Or is it simply too new to find customers. Or am I just a pansy?

looks cool. if SS interested me at all, i would probably buy it. It does have one obvious down side, though: it doesn't give you the opportunity to run a different tooth count for SS as it does for FG. I know that most people run a higher tooth count on SS than they do on FG, so that's a problem w/ this hub. If they could incorporate this design w/ the S3X, then they may really have something...

So you're saying, the torpedo's flip-flop method, 3 speeds, and incorporation of different ring sizes?

well I'm saying that having 3 speeds would eliminate the need for different ring sizes. This way, you can easily switch between FG and SS and also use a different gear ratio for each. All I know is that it kinda defeats the purpose of having a flip flop if you can't "take it easy" on the SS side...

EDIT: I realize this sounds over the top, but all this stuff is over the top, so yeah...

I've never ridden one but I like the concept behind it. I wish you could switch remotely (on the fly) from the handlebars though.

When the Torpedo F/F was announced, some posters said they could loosen their axle nuts, shove the wheel forward, unship the chain, pull the wheel, turn it around, stuff it back in the track ends, reloop the chain, pull the wheel back true, properly tension the chain, and retighten the axle nuts quicker than one could spin the Torpedo hub's screw.

If you see it on the internet, it must be true.

Yep, a trade off for convenience. Of course, other things like tensioning the chain with sliding drop outs or an eccentric bottom bracket can make it a royal pain to run a different tooth count, and unless you carry an extra master and links and break the chain, the difference in tooth counts can't be large anyway. Pick your compromise.

I just bought one of these and am having it built up with a Sun rim for my Paddy Wagon. I had been thinking about buying one for some time, but once I put fenders on the bike I realized that the flip is even more a PITA and pulled the trigger on the purchase. I live across the road from a golf course so my rides around the neighborhood are hilly and the SS option with the turn of a screw sounds like a good solution.

We'll need some pictures and a full write-up after you get rolling on this.
