Here's my question.... I built up a Dobermann Pinscher as mainly a dirt/park bike. I was wanting to run it SS and currently am.

Can you be competitive at all running a SS bike? (I am in the midwest so don't get to race a ton of dual/4X.) I wanted kind of an all around bike. Would I be better off going to a 1X9 setup? What kind of guides would I be looking at for a setup on profile cranks without mounts on my frame?

The fork is a slammed 4X that I can always put stock internals in if I am planning on doing a serious amount of racing at a given time.

Thoughts? You can PM me if you don't think the reply belongs in this thread.

Thanks

i am racing some 4x this year and have a pincher on 24's
i am converting. i think the best will be a SS rear hub with 4-5 gears.
you get the dishless quality of stiffness and great chain line.

drop whatever fork to like 80mm and you are race ready.

i have done SS in 4x is all about the gate, you got to have a
gate gear.

So what gear do you run (or would you run on a 26)? Right now I have a 4X set at 72mm. I can get internals and bump it to 80 if needed.

naaaa for most tracks thats fine.

i am setting mine up with a 32 - 12-14-17-21-25 with 180's
i think for about 6' 180 are mandatory for 4x.

180s? Damn, I thought it was the other way around. I thought you wanted shorter Crank arms i.e 165 for Slalom and 4x so that you can speed up your cadence quicker. So If I'm 6' 1" I should be runnin 180s?

So how does that convert to 26" apx? I am running 180s as well. What are my options for chain guides (I'm not used to running a BMX style crank)? Can I get enough chain tension with a long cage derrailleur or is everyone running short cage?

Thanks for the tips. Trying to make this thing as versatile as possible.

Your Dérailleur cage length depends more on your Gearing combination. I don't think the chain tension is any different between a long or short cage Dérailleur.

I was under the impression that you could get higher tension with a short cage. Either way I have an X.0 long cage sitting here unused that could be put to good use I suppose along with an X.9 shifter. And what are my options for a chain guide since the frame doesn't have mounts? Lot good extra gears do me if I drop the chain out of the gate...

And a pic of the bike so I don't whore this up with nothing but words. Right now it is at about 33 pounds I think with really heavy wheels. When I come into some cash it will be getting lighter rims.

yeah, i would only use a short cage. sram pref. b/d they don't bounce around like a shimano. watch this


as got guide an e13 has bb cup mounts, guides with weird cranks
sometimes are a hard mount, but i think e13 does the best job
fitting everything.

bcd, by 180's do you mean crankarm length?
Click to expand...
yeah, but its debatable. i like 180's b/c i am not a huge guy and
need all the leverage i can get in getting my bike moving. light
wheels are just as important though on gate snaps.

What is the geo like on the turner 4x's? Specifically the TT length, BB height, wheelbase, CS length and HA?

Thanks

The Turner 4X numbers:
TT 22", BB 13" (w/100mm fork), CS 15.9", HA 69, not sure of the WB, I'd have to check.
Very sweet ride if you can get one.

If you had to pick one gear to race 4X/DS with what would it be? (26" wheels not 24") I am thinking of trying it SS before dumping money into a new derrailleur, chain guide, etc.

I think it depends on the course, I've done DS races where SS guys did awesome but I've also been to races where they've maxed out their gearing 100 feet into the course. Give it a try first, you'll have fun regardless.

I think you need at least 3 gears to be legal...at least that's how it was a couple years ago.

Here's my old bike

They aren't very Strict about that rule unless you're at really top level races. I did a bunch of Norba sanctioned races last summer and Collegiate races last fall and there were plenty of people running SS.
