Dingle, dangle, dongle.

I just had a quick think about Surly Dingles and a 17/21 Dingle coupled with a 46/42 combo on the rear would give you a choice of roughly 73" and 53". There's lovely for hilly rides and the beauty is you don't need long slots as the wheelbase wouldn't change much. To get a similar range of gearing with a flip flop hub and a single ring up front would mean a significant change in wheelbase. Lets say a 46/17 combo for the 73", so you'd need a 23 on the other side of your flip flop to get the 54". I think that would mean about a 3/4" change in wheelbase.

I think I may have just solved my commuting problem - I live about 460 feet higher than the station so I was thinking I couldn't do it fixed. A gear suitable for the ride in would be totally unsuitable for the ride in. With one of these beauties on the back it wouldn't be a problem at all.

Now I'll have to sell something to fund building a new commuter hack.

Great minds an' all that... I'm contemplating a Dingle as part of "fixing" my '64 Carlton! I might run with just one front ring and thus have only a small ratio variation. The drop outs are long enough to accommodate a 2-3 tooth difference at the back I reckon. Easier change than a double fixed. The chainline will be an acceptable compromise I think.

With a standard double the chainline isn't spot on anyway. The spacing of a double is wider than the spacing of the Dingle. So I think the chainline with single ring will probably be as close as with a double. You need a 9 speed chain for a Dingle so it can cope with a much worse chainline than you'd get with a Dingle anyway.

They look like a good idea. The Rivendell Quickbeam had a double on the front and something on the back?

until sturmey start doing the old ASC again.

What do you mean?

Can you buy them now and do they provide 2 fixed gears from one cog for the price of a dingle and a double chain set?

SunRace Sturmey ArcherHello Everyone,

I would first like to thank everyone for their interest in our upcoming remake of the ASC. As we grow closer to production I will be posing questions on our blog www.sunrace-sturmeyarcher.blogspot.com regarding what you would like to see in the final production model.

The first question is regarding the acceptable amount of backlash in the hub. Meaning the amount of slack there is before engagement. The original was quite sloppy in this regard but we are interested in your opinion. The question is up now in the form of a poll and if you have a minute and could head over to the blog and add your 2 cents I would greatly appreciate it!

the asc is a planet geared fixed 3 speed hub, sort of like the AW, but fixed.

or was. when they appear on ebay they usually go for about 300 pounds.

sturmey are thinkign about remaking it.

but you knew all that didnt you?

They've been promising a new ASC for a few years now, so I wouldn't plan around building a bike around one any time soon.

Also I wouldn't expect them to be particularly cheap when they do arrive. They're liable to be made in very small numbers, it's not exactly a mainstream product, so I think you can expect them to cost considerably more than the freewheeling model. While I'm sure they'll cost less than originals tend to fetch I can't see them being less than £100. So in terms of price you're not looking at their being in the same price range as a Dingle.

Having said all that I'm already saving up.

Sorry to resurrect an old thread, but I am considering a Dingle for riding in the bumpy Cotswolds.

Does anyone have experience of using one of these, with a single chainring, for a decent length of time? I'm interested to know if there were any problems with chain-line or undue wear etc. I already run 3/32" so that wouldn't be a problem.

Any advice gratefully received. Cheers folks,
Don

I've NO practical experience of these, but I cannot see any reason in principle why, in particular, chain line should be a problem. If the 'line is mid-way between the two sprockets, then each is going to be only 2-3mm "out" and that is IMHO within the acceptable.
Main "problem" with a single ring is that (unless one has VERY long drop-out slots!) will only be able to accommodate say a 2T difference without altering chain length. May still be worthwhile depending on needs/terrain. But I'm sure you've figured that!

don_don

Thanks meagain. I think I will try one out. I reckon I could get away with the 17/20 which would be ideal. The main concern was the chainline, but as I think you already pointed out, with 9 speed it should be OK.

I'll come back in a few months and report back!

Cheers

Streak
