London Fixed-gear and Single-speed SJS Cycles

I came across this bike a while ago on Velospace.... a guy had a prototype.... I'm not sure whether they are in production yet, but you can order them from Geekhouse, It's called the 'Rockcity'.... frame and forks $899.



What do u think?

I like...need those cranks/chainwheel for my set up

$ 899+tax= Roberts custom.

ok maybe not ,but nearly

They are Paul Pure Road cranks - sprayed or powder coast white.

You can see the heart/diamond/spade/club card designs on the chain ring.

Stef, is this not the pursuit bike that u wanted?

i spoke with marty from geekhouse about these ages ago...he's really cool....nice frames.....more street tough than track light!

Whys the stem so high?

to compensate for the low front end i guess?

Yeah but then just use a regular frame. Think it kills it when people do that with lo-pro frames.

(not talking technically mind, just looks ;) :p)

Pursuitengers.

isn't it a bit silly to raise the bars on a pursuit bike? i mean, isn't the point of having the small front wheel that you lean more down and thus reduce drag?

edit: stated before, sorry bout that, need to read all the comments before i post...

marty from geekhouse is a great guy. he offered up a custom built frame (to be custom built for the person) to the first out of towner at my friend's 'departed'-themed race. he's knows his shit about frame building and has been at it for a while. he used to race downhill and started geekhouse building mountain bike and downhill frames but has since branched out to pursuit-style frames. he can put together other types of frames but i don't think he's in the custom-making business right now. he eventually wants the above model to be a 'production' bike, but i'm not sure if he reached that level just yet - the last time we talked (in august) he was still working on getting a bigger workspace i believe.

the frame is for two 700c wheels but is relatively lax for a pursuit bike. the headtube angle and fork don't cause toe overlap (atleast not when i was riding around on that bike). he sold the bike (with the parts on it) on e-bay over the summer to put more money into his business (though i would have kept that sweet bike).
he did a lot of his work with the help of the guys at A.N.T. (http://www.antbikemike.com/) who make really interesting and classic looking bikes - some of the stuff they displayed at their showcase over the summer looked amazing.

regarding the whole riser/raised stem thing - most people who are in the market for pursuit bikes these days either buy older 'funny' bikes with sloping tubes that takes a 700-650 or a 700-24 mix of wheels or buy some of the 700-700 production bikes (like geekhouse or affinity http://www.affinitycycles.com/ - though i've never ridden on the affinity one before).
personally, i'd throw tt bullhorns on a pursuit bike if i wanted it, but most people are looking for something moderately comfortable and not using a pursuit bike for it's intended purpose

also, uci has banned using 2 different size wheels, and i think the physics of it was proved wrong - that having a 650c wheel in the front has more rolling resistance which negates the aero-ness you would have by having a lower front end.

Does that build even have a smaller front wheel? I can't tell from that photo.

in the picture both wheels are phil wood high flange hubs laced to velocity deep v's (700c)

Bike looks nice mind.

whats the weight of the velocity deep v's? sry for the ot...

i like it overall, front fork i'm still on the fence though.

They say 520 grams.

ahh but can they be trusted?...

:)

Or tippexed...

I think downward sloping top tubes on street bikes are pretty pointless, especially when you have to jack the bars straight up to where they were before. The only reason is for looks and it doesn't look that great.

That fork is from another dimension, SO ugly.....it's right up there with the ones from brooklyn machine works.

nowt wrong with my bmw fork....so long as my bike is less ugly than me i don't give a FUNK!!!
