fork head/steerer tube od?

hub axle od and length?

rear shock bolt size?



there are a few dh CO's that have jumped on the band for fiddys and i think i could mad some cool stuff for them too.

here are some bike stuff on fiddys.



storm had a pro dh team once and made frames.







foes . but you know that.

here is a fork modded by a dh bake mfc. astrix

both have shimano disc brakes.







here is the fork i would use Marzocchi Monster T

- External Rebound & Compression Damping Control

- External Compression “Bottom-Out” Control

- 40mm Aluminum Stanchions

- 20mm Dedicated Axle

- Handlebar clamp & reduction shim

the travel could be adjusted and spring rates.

Hi Alex, nice to see your interested in 50s! Be prepared to empty your wallet!



I dont know all the #'s your looking for... but...



Tires are commonly 2.5 and 2.75 width. Rim diameter is 10" (although its about 11" if you measure)



Bearings are set in cups which press into the frame.



Thats about all I know offhand... maybe someone else can help you out.



Btw, your website is nice! DH mtb's are pretty sweet, I have always wanted one.

come on man give the guy a break, I see you make tons of spelling mistakes in your posts as well :roll:
Yah Matts good at correcting other peoples grammar but making the same mistake himself.



Sano boards



I say sponcer, I get corrected, I say sponcer again, he talks shizzle to me and says its spel like this "sponser" lol
Doesn't the bombshell suspension look like a black and red version of the Marzzochi Monster T? Uh oh. Looks like we have a lawsuit on our hands. :mrgreen:
Uh... Bombshells are inverted forks buddy.

Even if they werent inverted, they look nothing alike :roll: :roll:

hows the clamp on the bombshells ? i want them but am afraid that im not going to like the position of the bars. i am currently using a tall and fwd clamp that i like. ive tried the BBR clamp and feel its too low and cramped. is the bombshells clamp like the bbr or are they highr cause the forks are tottaly different ?

haha, word. I don't make THAT many spellig mitakes, 99% of teh time it is becasu I am typnig to fast, and here on planetminis my internet is so slow that I have to wait like a minute for the text to appear of what I just typed. And I told you it was sponsor! not sponser! :twisted:
The clamp on the bombshells is great. Its got 2 positions. Forward and back. And If you ever get a different frame, its 1 inch longer so thats a plus. Also, with the bars in front of the forks, it makes it very hard to ride. Thats why I dont care for aftermarket clamps for stock bars.





PS: Matt, you told me sponser, sponsor is the correct spelling :p

Sorry, I did not mean the monster t forks, I meant the astrix forks. Must be the vallum.
