SRAM S7 experts, a question:

I have a rear wheel with a SRAM S7 gear hub. I like the fact that it has a coaster brake, but am not (at least not for now) interested in the gears.

Is there a way I could run this singlespeed without the clickbox and gripshift? I'd like it to be constantly in the direct transmission (I think that's gear #1).

Direct drive on the S7 is 4th gear. You might be able to jam it up in 4th somehow, but I wouldn't count on it. Cheaper to buy a single speed coaster hub for $10.

Sell the SRAM on Ebay, it will more than cover the costs of the hub you really want. As a matter of fact, if you are looking for a buyer, keep me in mind.

Thanks, right you are, it's gear #4.

Now, the question is how do I jam it up to that gear?

I am in Finland. I can't buy a single speed coaster hub for $10 here. Not even $20. Actually, I won't get a coaster hub in Finland for less than $70. And we still have not accounted for rim and spokes!

I have the wheel built with the SRAM S7 already. I am sorry if this seems like a waste to y'all, but it's really the cheapest way I can get a coaster brake.

Both Shimano and Sturmey Archer make single speed coaster hubs that are very inexpensive ($10-$20). Even in Europe, they shouldn't be much more. As for the rim, use the one you already have with new spokes. As for that S7 of yours, I'd be glad to purchase it.

Well, if someone can point me to a place I can order a coaster hub online from, and makes a calculation where

price of coaster brake hub
+ postage of coaster brake to me
+ cost of 36 spokes bought at LBS
+ shipping costs of the S7 to the US (about $45)
- what I could get for my S7


is a negative number, I am all for it.

EDIT: I checked, and Economy to the USA for 3Kg is $45

Otherwise: any idea how to fix the gearing into #4 on the S7?

The main issue is that I am ignorant and don't know how the clickbox actually works. I suspect that it probably moves that long metallic pin/axle in and out, but I don't know. Hence I am asking.

Cheapest I could find is for about $30 on eBay in the UK:
http://cgi.ebay.co.uk/STURMEY-ARCHER...QQcmdZViewItem

problem is... I actually can't even buy the thing, as the guy doesn't ship outside the UK.

Do a little experiment: Take the clickbox off (as I recall, there is a little thumb set screw on the rear side to loosen, and then the box just slides off), and then pull the little push rod out. I think this will leave you in the direct drive gear, which is fourth. If this is so, you can just strip off the shifter and cables, and you are permanently in 4th.

-but keep all those parts in a bag somewhere, it would be a shame to lose them.
-and maybe plug up the hole that the clickbox used to cover. Not sure what with, but something.

They don't have a singlespeed coaster brake hub. Their prices are outrageous (multiply by two to get the price in US$) and there is nothing to suggest they ship outside the UK - which defaults to UK only.

I've done this once, by pure chance - the clickbox failed and slid off. The plastic index thingy broke. Basically, there was no indexing and the rod was just dangling. Anyway, the speeds were just changing somehow randomly, between the #5, #6 and #7. I was going really fast for a while

I have bought a new clickbox and two sets of indexing rod + indexing plastic indicator.
