...or 'Schtickel v. 2.0, for short. ;)

I have been kicking around the idea of a fat bike for a long time. I really liked the idea alot, but didn't think I'd ever see the kind of snowfall that could justify such a dedicated bike. In recent years, however, it seems more and more folks are opting to ride them on dirt!
:thumbsup: :cornut:

From about the time that I received the first frame from Steve, I have had a couple tweaks in mind...as well as the pipe-dream of being able to run a fat wheel in back :).

Over the course of the winter, I mulled things over & came to the place where I could really see the possibility of building a bike that will see 29er wheels 80-90% of the time, while still affording me the opportunity to build up a full on fatty!

This frame will feature:

150mm Maxle rear
83mm BB shell
New 44mm head tube to run tapered steerer forks
A design around the new 140mm Reba
Hammerschmidt


The real magic, however, was how Steve Stickel managed to squeeze all of my requests for the 29 AM frame, along with a Hammerschmidt AND fat wheels into one package. Once again I am singing the guys praises...he is such a great builder to work with from start to finish! And his work...well, I think it speaks for itself.

Some concept art







Geometry I sent Steve



A Few Goodies




Build Pics







































Plenty of room!










We're almost there...then off to paint!!! :thumbsup:

THis is focking sweet!!!

Well done!!

Please don't paint it white. That would make me cry.

nicely done!

I am flattered you used the idea of my bike to build around it a phat version and its very hawt. It will compliment my stable nicely when sent to me as while we dont have snow, it will be perfect for cruising the local beaches checking out the hawties

Teamdicky...you hit the nail on the head! :D

Thanks for the swell comments all...I am really gonna need your support for the next couple weeks (until delivery) ;)

Enel: how did you calculate that? The delta in A-C from sagged 140mm Reba to Enabler fork is 36mm (that's without considering the difference in diameter between fat wheel & 29er wheel). It might net a bit over 1* in HTA, but I doubt it will be.75" at the bb. Short answer...175mm crank arms :)

PS. ...and yes, this will be a very versatile frame (swiss army!). :thumbsup:

I don't know the difference in wheel size so I assumed they were the same.

30% sag on 140mm travel = 42mm
546-42= 504 a-c at sag
504-468= 36mm
36mm X sine 70 = 34mm vert drop at the front end.

Now to calculate the drop at the BB. I am not sure if I am doing this correctly, but assumed 16.75 chainstays and overall wheelbase of 43.75.

16.75/43.75= coeffecient to determine the portion of front end drop that will occur at the BB = (0.38)

0.38 X 34mm = 13mm =0.5"

12.0"-0.5" = 11.5"
12.25"-0.5" = 11.75"

It will probably be more since my coefficient is based on the WB and it should really be based on the chainstay divided by the distance from rear axle to headtube horizontally, but I don't have that number.:D

Please don't let all this geekery mess with the b1tchenness of the bike.:p

If you have a better way to calculate this I am all ears.

Do you know the difference in wheel diameter?

Was 1.5 a possibility, or no can do in steel?

To say this frame interests me is an understatement.
