Spec TriSpoke Cassette Surly Fixxer?

Someone told me the Surly Fixxer kit does not work on the earlier carbon fiber finish Specialized Trispokes (2nd gen, not the original black heavier wheels). I think the wheels are from 1993 or 1994. I have a pair, would like to convert them for use on the track.

Front - I need an axle, I think 9x1, plus nuts.

Rear (cassette) - the Fixxer? Any other ideas?

I also have another front/freewheel, but it's a clincher, and as far as I can tell, I can't put a lockring on it, so it's no good for a rear.

thx

aki, i can't answer your question about surly fixxers and trispokes, but i can say that it probably won't be a problem to use the other front/freewheel on the track. It's completely possible to crank on a track cog and, for a bit of added insurance (maybe only psychological), screw on a bottom bracket lockring. On the track you won't be applying anywhere near enough backpressure to unscrew it; some tracks don't even require lockrings. It's an option if you can't figure out an answer to your question about the Fixxer.

Or you could sell that threaded one to me...

heh.

I guess I can try the Fixxer. If nothing else I can convert some other Shimano freehub wheel to a track hub.

I just realized NE Velodrome opens in a few weeks (for racing - they're open now a few days for "open riding") and I have my stupid big gear, the 105 triple crank arms, a stem that's too long/low, and a super cheap front wheel. So my shopping list is 1 - get some lower gears; 2 - find a shorter stem or put crit bars on the bike; 3 - find and convert a nice front wheel (prob the TriSpoke).

The Trispokes both have some dings in the sidewall (i.e. dented rims, fixed with channel locks ) so they're not great for road (poor braking) and ideal for track.

I'd like to go to 1/8" on the chain too.

If it's just for track and not road use you don't need a lockring. If you're putting enough backpressure on to spin it off, you already have *much* bigger problems. I've raced for years without a lockring and know very few people who bother with them for track use. My race wheels until recently were a pair of old tri-spokes that couldn't take a lockring, and I never had trouble with them (though they're kind of flexy and it was very noticeable at speed on Encino (short and shallow)). I finally killed one in a crash and moved the rear one to the front (quick axle swap) and finally have a disk in back that's much stiffer and handles better at speed on Encino.

(edit: and I wouldn't bother with a freewheel lockring-- it will just be a pain and not really add any insurance)

thx for the info. I'll ask what the deal is with the lockring. I'm wary about not using one, not because I'm some monster backward pedaler, but because I tend to be very risk averse.

Ultimately I don't think it'll make a big difference. I think I have more significant things to worry about. I guess it's like a Cat 5 asking whether or not the extra couple mm of rim height makes a difference. I'm so new to the track that I feel like I'm learning something significant every time I go.

I carry lockrings in my bag because I've heard that some tracks require them, but I've never really encountered one that does (though I don't travel to all that many other tracks). Crank it on hard and you'll be fine.

I carry a pipe wrench because the adapter for my tri-spokes doesn't have flats, and it tends to come off the wheel before the cog comes off the adapter. It's also good for entertainment when people ask why the bag is so heavy...

Your chainline will be very much off if you do this. I know, I tried, and I ended up buying the Hed track adapter from the Hed website. It worked just fine with both an old Hed disc and a Specialized tri-spoke. This is, of course, about the wheels with the freewheel body, not the freehub.

Update: the original TriSpokes used a Dura Ace freehub body. Fixxer is only for Ultegra bodies, at least for that era of DA. Therefore no-go on the Fixxer, and the reason is the DA freehub body.

Thinking of my next step.
