What a cock tease. You throw a few leading words, show some pretty trick pieces and then fail to elaborate. What is your eventual ratio? That dura ace crank has to have 130 bcd for crank arm spacing, right? I tried counting, and then I got a 110 and 130 bcd chainring out of my crap box in the garage and held them over the photo, but wasn't able to confirm suspicions.

My guess is that you have an evil plan to ride the Tour Divide on a titanium 29er with a 38x21 ratio. Regardless of whether I'm right, it is really lame that you were so lacking details for the curious. I hope a moderator shuts down the thread.

Don't let umarth rile you. He never hits "reply" until he's downed at least 5 beers...

He rides pretty well drunk, tho.

38x18, or 19
No dingle? After I posted I immediately regretted not supposing you'd get an 18/20 dingle cog so you wouldn't be spinning like a madman on the fireroads.

You are certainly in better shape than me to even attempt this ride, so I have a couple questions about the gearing- why so high? Getting up those climbs is going to be rough- is it to peg a medium range in order to avoid spinning out downhills and long flats? Can you climb with that ratio or will you end up walking?

What sort of tire are you going to use?

Have to walk some, always have felt a dingle cog isnt a single speed..... 85% of the climb are doable with that ratio, and lotsa down and flat to get spun out on

I have never understood that idea. I have a cross bike at 39x15. Everyone accepts it as a SS.

I have a mtb. It is 34x20.

Both are legitimate SS bikes. One does round town commuting/SS. One does mtb SS.

If you could do one bike for both, with a ratio for each purpose, why can't it bee a legit SS? Anywho, you got some game. I defer to your professional opinion.

I just don't like the look of dingle's (no experience with them what-so-ever) because if you're going to have 2 rings up front and 2 in the back you might as well just throw some shifters and derailleurs on it and not have to worry about manually moving the chain. In my opinion it's just a multispeed bike without derailleurs and shifters.

Let's not get to far into this, but I will briefly say that if you've used one you would know that is wrong. It rides and functions exactly like a singlespeed including the lack of drag and bouncing chains that derailleurs introduce, and you don't (and should even really be able to) "shift" while riding. The idea is that instead of removing the wheel and pulling out a bunch of tools to change gear ratios for flat vs hilly rides or mountain vs commuter, you just loosen the wheel and move the chain over. It's pretty much the same idea as having a flip-flop hub with two different size cogs, except it's quicker to change and works for disc-braked hubs

I totally realize all of that. I should have specified that I was referring to the look of the bike, not performance. I love the idea of the dingle, I'm just too big of a bike snob to have 2 chainrings and 2 cogs on my singlespeed :thumbsup:
