Anyone using an On-One Inbred with a Goldtec?

I want to run 41 x 15, and it's for road use. 36 x 13 is about the same, but cogs so small feel horrid, accentuate any out-of-roundness and aren't as efficient.

It fits OK on my Cannondale M1000 frame, but that has vertical dropouts and the ENO hub never worked properly for me - it kept creeping every time I rode up a steep hill. Hence the frame swap.

Hmmm, smaller cogs may have their negative points but is dropping a total of 7 teeth really gonna make a noticeable difference?
Also, would have thought larger cogs would be more likely to have out of roundness than smaller ones seeing as there's more room for error?

Seems like your bike's a bit of a bodge, you have a frame which requires a 50mm chainline and a hub that gives a 46.5mm chainline. The incompatability can be cured by using a different hub or a smaller chainring, with which its still possible to achieve your desired gearing but you'd rather take a hammer to your frame?

Hammer? This is precision work. And the bolt-on cog solution is actually a bit naff in this case, since I'd have a big heavy freehub sitting there on the LH side of the wheel going rusty. I'd rather have a double fixed hub.

Trust me, this is cheaper than the original plan of buying an early 1990s MTB frame and having track ends added.

well you could just get a front disc hub and respace it....

Yeah attacking your frame with a hammer is cheap, doesn't mean it's right.

And it isn't precision, crimping the tube in a purpose made hydraulically powered machine before it's assembled into a frame is precision (and even then it leads to a weaker frame).

This is dumb.

Well...the frame has arrived and it turns out there is clearance for a chainring of dinner plate size with the Goldtec chainline. I guess when On-One specify a 50mm chainline they are allowing for chainsuck if you run it geared - it would probably manage a 42mm chainline as a fixie.

So the frame will remain unscathed.

Next problem...how on earth do I fit a rear mudguard...there is no seatstay or chainstay bridge...?

clip onto seatpost - look at zefal swan.

I've got a rack fitted, with a length of UPVC window sill bungeed to the top (colour co-ordinated with the frame), with an additional length of cardboard wrapped in black gaffa tape attached to the the rack's seatstay brackets, part of which is angled down to nearly touch the tyre.

Simple, and devastatingly attractive.

I thought of drilling the underside of the rear fork "crown" (it's a wishbone stay design) and tapping for an M5 bolt. I can probably rig up a clamp around the base of the seat tube (I'll have to search my world-crushing collection of rear light brackets), and use P-clips on the seatstays.

Would this work with those big clearances?

Why not just get a crud catcher. The rear guard is surprisingly effective on my cycloX frame, and in a MTN frame you should be able to position it lower. The down tube guard thing is'nt that effective though. I'm only really using it to keep the road slush from collecting too much on my body.

PS: have you checked heel clearance with the newly proposed chainline? If it were me I'd be tempted to go with say 47mm chainline regardless. I like the sound of a fixed allweather inbred, keep us posted ;)

Crude utility, FTW:

Hey BMMF, I was riding behind you 2 nights ago (through Clerkenwell) thinking to myself I really need to get on-one based bike happening. I know you probably think your bikes a 'Crude Utility' But thats what I want for banging round london! My old pug is a little too flexy and just feels worse everyday.

Yeah, I've had my eye on an inbred for a while. Mind you, I do live in Norfolk.

But seriously, I want one.

It's been working pretty well for years - the gaffa tape up front stops water flying off the front wheel into my face :)

I hope I wasn't riding like a twat, unless my new winter regime of commuting very slowly in a 58" gear is inherently twattish. It may be. I'm not au fait with current trends.

Extra info: the rear brake is set so that even when the lever's pulled, it won't contact the rim…

…but I can use the barrel adjuster to 'activate' it, for when I've got my son in the child seat and want extra security.

I think you'll find the term is active8 nowadays granddad.

Unless it's changed again back to activate. I'm rather out of touch.

I notice you've gone for the en vogue granddad rather than the oh-so-90s grandad version.

Mathematics is my wife, language is my mistress, and above all I must practice self love.

practi*s*e - it's a verb in that instance.

No too much of a twat! I was following for a while but there was a group of annoying riders coming up so had to pass and get outta there. (also needed to piss - too much info?)

It's actually very important not to ride a bike for too long (or do any potentially strenuous exercise) whilst needing a piss. You did the right thing :)
