Hub options for a 45mm chainline

[Ivan]

I'm thinking of building a new fixed/fixed wheel to match up with my Sugino RD2 chainset. At the moment I've come up with the following:

• Continue with the spacers and no lockrings that I have now, on yet another PlanetX
• Goldtec (pre-2010ish?) - try and source one secondhand?
• Halo Double Fix-G

Any other suggestions? The Halo hub does look pretty cool, I like the chainline adjustability but does seem like slight overkill.

Does it have to be a double sided hub? If one cog is enough I'd go for a converted front disc hub and a bolt on cog from velosolo. Or a new bb and a standard 42mm hub.

Thanks Chris, the velosolo solution does look pretty good, didn't realise you could space it to 46mm and run it undished, and have always got good service from them. Time to got off my arse and measure my chainline exactly I think. Can always carry another cog loose with me - it's not like I'm trying to win the Fixed Wheel Challenge or anything

I think phixie would prefer it if you weren't able to swap cogs when you were competing in the FWC anyway.   

Besides, winning the FWC is overrated - what you want is to come second.

On-One hub and a longer BB?  I think the hub is built for a 50mm chainline (Hollowtech 2 crank assumed, you see).

[Chris N]

I'd assumed Ivan wanted a 120mm hub as he was talking about the Halo Fix-g; the standard On One track hub gives a 42mm chain line - it's the 135mm double fixed that has a wider chain line for MTB cranks.

Phixie isn't that fussed about an extra cog.  After all double sided fixed hubs have been used since the year dot.  He might raise an eyebrow, though, if you had a selection of cogs, but chain length would probably restrict the more extreme changes.

What about if you had some kind of spring loaded device that adjusted for varying chain length

Anyway, I've decided to give the velosolo hub a go (on my 120mm Dolan FXE frame), trying to stay away from fiddling with the BB/chainset setup if I can avoid it. Thanks for the suggestions. Based on the two audaxes I've ridden fixed so far, feel fairly confident about my gear choices, and can always take the old flip flop wheel if struck by indecision.

What?

With a parallelogram movable design to enable it to accommodate a wide range of rear cogs?

Moved by a lever-operated cable?

It'll never catch on you know.

Yeah, if you were going to go to all that trouble you might as well stick an engine on

That'd be silly.  Put all the rear cogs bar one inside the shell of the hub, to protect them from the effects of Skog^TM and save all the mucking about with spring-loaded wossnames.

Can we please give then  their correct name -  sprockets  although once canned as above you can indeed call them cogs.

[rogerzilla]

No you can't, they're suns, planets and annuluses.  Or annuli.  Or gear rings.
