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)

650 Traitor Prototype

Anyone seen this? It is a prototype from traitor for a 650 aggresive urban fixed gear/singlespeed nick named it the 650BMX bike. It looks pretty good and I like the front disc through the headset. pretty cool for barspins and brakes.

no shilling or trolling just thought it was interesting as so many companies are releasing trick frames.

awesome, looks like a conversion with a 650 front.

only pursuit/TT bikes should have mismatched wheels. on that note, only bikes with mismatched wheels should have a forward sloping tt.

...did you look at the picture?

Both wheels are 650b, and the top tube doesn't slope forward.

ETA: I also want to mention that this bike looks totally sick. I would ride the **** out of this bike.

i dunno, kinda looks like the rear is bigger, probably a trick of the eye.

and because i thought it was 700 rear 650 front (like that awesome red your dead bike) i went off tangent on bikes with mismatched sizes in general

yep, a longer look shows indeed they're the same size.

why not just convert an old mtb and throw on like 32 commuter tires? no barspin?

So, why 650 wheels? I'm curious how you tighten the headset if the brake cable goes through where the preload bolt normally goes.

well as far as my understanding 650 because it is comparable to a 26'' wheel, which is a standard mtb wheel and common on dj/park bikes. Manufacturers readily have 650 wheels also. I'm sure it probly drops the center of gravity as well but it doesn't look like the bottom bracket is raised.

and you know you want to be able to do this

so I say get a dj or park or street park

I'm not into BMX or FG tricks but this is a nice looking bike. I'm a big fan of the front disc brake.

i think it's cool other than the little cutout here in the front fork mount... i think it looks nice, but why? seems like it would greatly weaken a part of the bike that really needs to be beefy if it is designed for "bombing" and "trix"

it looks like the headset is a prototype proprietary headset for traitor. it even says "traitor bike co." on the top race, and they don't sell headsets right now, so who knows exactly how that's set up *shrug*

anyway, regardless you can do this with most any threadless headset, you just have to put your fork/stem/headset together before you run the brake cable through, and if you need to change anything you gotta pull the brake back out. when installing the headset, once you have tightened everything down, it is the stem that holds everything together. the topcap and bolt can really be removed. if you just take out the bolt you can run the cable down through the topcap and starnut down and out. i am more curious as to what keeps the topcap from popping off.

anyway, it's a common misconception that the topcap is there to hold the headset together or that it's some sort of back-up for the stem. a beefy topcap might be capable of saving your ass once or twice, but it's not designed to... and proper bike maintenance (checking your stem's bolts) is a much better safeguard than a mm or 2 of aluminum.

650's are in between mountain bike 26" wheels and road 700.

700 - 622mm diameter
650b - 585mm diameter
650a - 590mm (i think)
26" - 559mm

Why do they make different sizes of wheels at all?

As someone who has no interest in tricks at all, I still like this thing a lot. I just imagine it modified for rack and fenders for wet-weather riding. I mean, the thing looks like it's sole purpose is to go into battle against idiots trying to lock up their cruisers and win.

This bike will likely cost over $1000.

You can have a mature* BMX cruiser with stronger (and easier to find) parts for $500. H*ll, you could even put a gyro on a cruiser and have back brakes, too if you prefer SS.

Why reinvent the wheel?



*mature meaning that all of the kinks and bugs have been worked out.

once you preload a headset and tighten the stem, you can remove the top cap bolt. the stem bolts will hold the tension well enough.

Yeah I didn't want to give the impression I'd be doin tricks on this thing. You sum up my feelings exactly.

why make a trick bike with wheels that aren't 700?

doing tricks i imagine you'll eat tires, 700's are much more common and likely to get on the cheap.

26's are much more common and likely to get related parts on the cheap.

26's made for downhill will surely be strong enough for any sort of tricking

650s (i assume these are 650c's, if they're 650b's that ridiculous, there's like 5 panaracer tires you can get in that size) are not made for tricking abuse. they're meant for like triathlons or touring.


just because you can doesn't mean you should.

First off, this is clearly a bike with more functionality than just tricks. I would ride this ****er all over town. Barspinz are just for gits and shiggles.

Second, you're... an idiot. 26 in wheels aren't "made for tricking abuse." They're made for mountain bikes. 700c wheels aren't "made for tricking abuse." They're made for road bikes. Even 20" wheels weren't originally made for tricking, they were made for kids bikes. There is absolutely no reason at all that a well-made 650 wheel wouldn't stand up to tricking abuse. Do you think the wheel knows it was only made for triathlons or something? It'll just refuse to roll when it realizes what you're up to?


just because it hasn't been done doesn't mean it shouldn't.
