White Industries Dos Freewheel: Best idea? Or bad idea?
 
It's two cogs on a freewheel. Tempting because as I'm getting more used to ss riding I'm able to use higher gearing, and could switch over when I'm ready. But could it cause chainline problems? Thoughts?

Linky.

Seems fine to me ... I wouldn't use it though, kind of superfluous. If I were going to run more than one speed, I'd get a three-speed.

jim-bob 04-29-09 01:23 PM

I like it. Haven't noticed any chainline problems yet.

No chainline problems, only chain tension problems. ;)

Once you go slack, you never go back.. ;)

It's not like you can shift between them. A White Industries freewheel costs $95, and the dos costs $120, so it's cheaper if you know your going to out grow the gearing...

What's wrong with a flip flop hub then?

jim-bob 04-29-09 01:51 PM

It's a lot quicker to flip the QR skewer open, push the wheel forward, move the chain to the other cog, pull the wheel back, and flip the skewer closed.

It also sucks a whole lot less with a dirty/muddy/whatever wheel.

You would need two $95 freewheels instead of 1 $120 Dos.

devilshaircut 04-29-09 02:01 PM

Just seems unnecessary, but if you want it, I say why not?

commutr4life 04-29-09 02:05 PM

I agree, not necessary...call me "dos-curious"

jim-bob 04-29-09 02:13 PM

Just make sure you've got a 3/32" chain to go with it.

Hirohsima 04-29-09 02:13 PM

I run a double double (DOS ENO in the back, and a road crankset in the front). I currently run a 45/50 front and a 16/19 rear so things are not perfect as far as chain length right now, but I am working on correcting. As long as the tooth differential is the same between the F/R gears, the chain length stays the same and you have two VERY different gears to play with.

Here are some pics of my old setup.

Fascinating...and both of you use QR? I thought that was a no no with ss, or is that just fg?

jim-bob 04-29-09 02:34 PM

I haven't had any problems yet, even in the low 2:1 gear.

As long as you get a decent skewer it shouldn't be a problem.

Yep, old Campy, Shimano, and Suntour closed cam QR's work great. You can't use aluminum exposed cam QR's (like Salsa Flipoffs for example), as they don't have enough clamping force and the knurling on the nuts can't hold like the steel of a good QR. Plus the Ti rod on mine never let me get enough clamping force (my guess is its slightly stretching when I use it). Aluminum QR's were designed for verticle dropouts.

I regularly climb hills on my SS, and no slippage. I clamp them pretty tight though, and I ran FG (with brakes) with no issues. I have zero idea or desire to skip or skid so can't comment on real FG riding.

Velo Orange brough in, or are bringing in, some tighter skewers. I've been thinking of doing if FG with with a Surly Dingle Cog.

rarebird 04-30-09 08:21 AM

get thee a tensioner, those surly ones are cool

Hirohsima 04-30-09 10:47 AM

For the road, I honestly don't see any reason for track nuts. They are a PITA, require a tool to remove, and they chew up dropouts. I rode for YEARs on horizontal dropouts on a geared bike and never had a QR slip. Other than stress from skiping/skidding, normal pedaling forces should not require anything more than a good quality steel QR.

I'm dying to see the 4-speed single speed.

Or, maybe thread a dingle onto an S3X and make a 6 speed fixed gear.

kergin 04-30-09 06:01 PM

Sorry, but how is this a SS anymore? SS == 1 gear ratio. Not two, four, or any number but 1.

elTwitcho 04-30-09 06:23 PM

Yeah at that point I'd just get a bike with a casette and derailleur and have a bike that could shift to any of 8 rear cogs in a fraction of a second.

Do you consider bikes with flip flop hubs to be single speed?

I'd love to see pictures of the complete bike. Cool idea.
