Hello folks

I'm a big fan of Kooka parts ... during my hunt for cool Kooka parts i bacame the owner of many nice litte Kooka parts :D ... my favorites are the parts in the "nightstorm" design ...

Do you have more pics? ... I'm still searching for a proper seat post in the blue or green splatter design ... ;)

here some pics (only the 2 stems and the blue crank are mine):













For more cool Kooka designs please have a look here: https://www.mtb-news.de/forum/showthread.php?t=221634

Thanks a lot Bertram

here's a set of cranks i just sold. there was no way i was ever going to mount them to a bike. too darn fragile. i've seen too many broken Kooka cranks to ever trust them onder me.

hummmm nice stem on that bike (the blue one) elevation ... you know who is the actual owner??? ... and the hubs ... Ringle??? .... and a Kooka seat post too ???
I own my stem at retrobike.co.uk from a member called gump ... thanks at this point again ;)
the stem was also available with a fade from black to purple (purple on the handle bar side ...) ... i think this will match better on a black frame (like mine :D ).
But i NEVER had seen a seat post in this design ... actually i'm thinking it's a rumor that these seat posts were build :skep:

btw: elevation ... realy NIIIIIICE Koga you have there (the purple one ;) ) ... i already saw it on retrobike .... i think your Kooka stem is one with a black fade at the frame side ... right?

@ Veloculture .. yes the first generation of the Kooka cranks (like yours) ware broken realy often .... but i think the second generation was a little stronger ... for cc use only


Hope my english is undersatndable ;)

Regards from germany (Dresden 35 °C *ufff*)

Absolutely

I sure do remember the BIKE Magazin lab test in which the 1st gen did indeed fail. The other fragile cranks in test -if I remember correctly-: AC and another pretty similar looking crossbar design.

I think I do have the second gen low profile ones on my Yo:



Somewhat later came the forged ones with fixed spider if I remember correctly.

Also got a Kooka part with another fun design; Rasta:

Jep ... there are a lot of differences in detail ... some of the stems (called klyde btw) has only a skew on the right side ... the other one is completely closed ...

look here :skep: :



The crank history is completely right ... :D

And what a niiiice Yo :eek:

I'll search an mtb-news.de ... there i saw a bike completely in rasta design ... with a lot of Kooka bits ...

the rasta design also was produced in 2 different ways .. one with and one without violet at the end ;)




So maybe we can enlarge the thread to a "KOOKA GALLERY" :thumbsup:

Regards Bertram

There were 4 generations of the cranks anyways. American Kooka first and second generation, all CNC made, seperate spiders held on by press fit and retaining bolt. 7075T6 aluminium. Canadian third generation one-piece cold forged from 7129T6 aluminium. Canadian 4th gen DH/FR cranks, reverted back to CNC machining, but the spiders fit a splined interface on the crankarm (1st/2nd gen was a square fit) and used two retaining bolts much stronger than the oldest cranks did. Also they were REALLY heavy.

Hey Bertram--the nightstorm cranks in the second to last picture on your first post (with the Ritchey chainrings) are mine. I would be willing to sell them--although the nondrive side has a crack in the square taper.

Also, look on ebay right now--there is a NOS set.

Jap .. the crankset on ebay is realy a perfect dream ... but it's the first generation ...
I would rather drive the crank ... so i think it's better to get a second generation crank ...
But realy nice "night storm" bit :D

@Oregon MTB .. thanks for the offer ... but the crack is realy perilous :eek: ... and crank arms in different paint ?? i think this looks freaky ;)

If anyone will sell the cranks (intact) in the green splatter design ... :cool: ... i'm your man

More Pics please ... :thumbsup:

Bertram

Yes the ebay cranks are first generation, standard spindle (ie 122/127) requirement, and in the 56/74/110 bolt pattern drilling. They're also damn light (my 180s were 395 grams).

Anybody have a nice closeup pic of a Kooka Rasta crank?

Do you think the 1st gen cranks will be OK on a road bike? I am thinking of converting them over with 50/34 chainrings to a compact system. Somebody told me with the 110 mm BCD, I can use a readily available BB.

How can you tell the difference between the later forged cranks and the early ones?

I bought two Rasta cranks 10 years ago on closeout; I have one with me in Japan but I can't find it. Gotta dig it out of my closet. So I'm wondering if anybody has a pic on hand.
