Is that an all aluminum frame?

ThePirk · Jun 2, 2004

cool frame
How much are they going to be runnin for? :cool:

BurlyShirley · Jun 2, 2004

i hate it.

Holy Geez I'm a total asshat for missing that.

Sorry bout that guys - and especially sorry about that Pete.

NICE!!

Very nice!

Also, very Brooklyn Race Link, how do they differ as far as geometry etc?

I see way more bb7 in it than BMW - and it sounds like you can get custom geometry as they are selling direct to customers.

The Kadvang · Jun 2, 2004

Looks pretty sick. I like that bashguard too.

really, more bb7, actually i think its like a perfect combo of the two, put into one sick rig

better put in your order now, so you can get next weeks ride. Will be sick with your new fork-

CreeP · Jun 3, 2004

perfect bashguard and pedals to compliment your raceface diabolous stuff.

the frame makes sense too. well designed (low cg, simple solid parts, decent ish standover in front of the seat) and looks well built too, look at the distribution of heat on the tubes from the welding, it's very even and doesn't ever get too dark. I couldbe talking out of my ass here but it looks like this guy knows his stcks when it comes to welding and brazing.

looks well heavier than a lot of aluminium stuff, but whatever. that's cool.

Don't forget it looks like something from Clifcat! Progressive linkage and high pulley.

Lexx D · Jun 3, 2004

Hmmm........I think I just found my new frame

. My 01 bb7 is getting replaced next year and since there's no more balfa this looks like my new toy. mmmm, mmmmm, looks good bitch.

and no i don't mean that thing from cliffcat. :eek:

rbx · Jun 3, 2004

hehehee funny coincedence i started a bike company called Darkside bikes a couple months ago and we are currently working on a similar design.(accept i am basing my design around a rohollf hub)
Looks cool tho! wish them best of luck

apparently a new dark cycles iteration:

buildyourown · Jun 3, 2004

That's sick. I was just thinking, "All that bike needs is a triangulated swingarm". Now just ad the 12mm thru axle and you'd have the perfect bike. IMO

Oh yeah, If the geo looks good i'll be putting a deposit down very soon. But what color :think:

Can't you tell from the rendering? They only come in Rootbeer.

Lefty · Jun 3, 2004

Men those pedals are the **** ..very nice...:evil: :thumb:

Those bashgaurds are evil too..

How would a triangulated swingarm be of any benefit in that particular rendering vs the original pic? Or were you talking purely aesthetics?

the long square tubes are ok, but a triangulated rear end would reduce or resist torque better.

and by torque I mean along the beam arm. lik eif you landed slightly sideways, the beam version might flex. the triange rear would not as much. or if it did, it would as an entire piece, not along the length of the beam arm.

A triangulated swingarm will be stiffer torsionally for a given weight. In order to achieve suffecient rigidity with a single tube, you have to have really high wall thicknesses.
Take a look at the proto. A round tube resists torsion better than a square tube (assuming same wall thickness).
There are a lot of exceptions to this statement, of course.

Lumpy_Gravy · Jun 3, 2004

Aesthetically that is one of the nicest looking frames I have ever seen. I love the thin steel tubing and fat Shiver stanchions.

Has it got the same suspension action as a BB7, Giant DH and Keewee Cromoeight? (but with balfa chainline of course)

Any figures on your geommetry for the race frame?

Any ideas on a floating caliper? as I hear some riders really dig them on the Giant and Balfa.

It works out at £1,196.45 in the UK which is a nice competitve price too.

is the hub gonna be frame mounted, ala nicolai? Or is it gonna be standard rear wheel placement?

buildyourown · Jun 3, 2004

People keep comparing it to a Balfa. While it has a similar chain line, the suspension is going to be much more progressive. The BB7 does not have a moto-link. I would compare it to a PDC DH-one or a BMX race link. The pulley on the dark does the exact same thing as a jack shaft.
And yes, I would be looking for a floater too. Some people say the BB7 doesn't need one, but I have tried mine both ways and I think the uber high pivot bikes NEED one.

Yeah because there are many similarities. But the one place it's truly different (and likely better) is suspension. The link will help make it more progressive which mine neede badly. My 01 would eat through the travel way to easy. A floater is nice but not needed.

I'm not arguing those facts, I'm no expert, but in the real world don't pivots flex, twist, and generally make a bike not feel solid wayyyyy more than frame tubes?

Brad23 · Jun 3, 2004

damn, I keep coming back to this thread, this is one sexy bike!!
I like the triangle rear, but not the drop outs or hanger as pictured, but that could just be some quick cad drawing.
11 lbs is not bad for a big rig and no doubt for steel.

Anybody want to comment on the feel of steel vs al for downhill.
I would think it may "feel" smoother since its not as rigid. Especially when pushed to the limits in a rough downhill.

Cheers, Brad

draco · Jun 4, 2004

brad it is noticeable. its not so much that you're like oh wow, I notice this frame absorbs vibrations better, because I can really notice that, even with 9" under me...

but you do.

you really do. its just smoother.

bulldog, what I at least meant was that 2 square beams, each nearing 2ft in length, and at least 20" unbraced, will flex a bunch more than several smaller tubes welded together. the only pivot that could twist would be the main pivot. and the triangle version helps address that because its welded several times beyond the pivot. i would say all things aside, ride one like that, and then a framed version, and you will notice it.

It's been a while, so I thought I'd post an update.

We're working crazy hours to get everything ready for InterBike. We're bringing a tonne of product there to sell. No frames for sale yet, but we're bringing three Scarabs down to help get the word out.

We' ll have our website up and running hopefully in the next couple weeks, along with a catalogue detailing all of our components.

If you're priviledged enough to be going to InterBike, come check us out, we've got a booth tucked way in the back.

Below are some pics that were taken for the catalogue. Enjoy!

Holy Moly that frame looks hot as a finished product.....I like that grey shade of paint they used.

Instigator · Sep 23, 2004

Damn, that is looking sweet!!!!!!!!!!!!!!!!!!!!!!!!!!!

syadasti · Sep 23, 2004

It still looks like the WB is too long - how long are the stays (effective length)?

Lennox · Sep 23, 2004

couple more older pics from darkcycles...
i want one :cool:

mandown · Sep 23, 2004

that is a sick frame.

those pedals are AMAZING!

MikeD · Sep 23, 2004

Yeah, what are the final geo #s? This looks like a very cool bike...
