SSCX Only!

I think your new uci coach stuff is messing up your free radicals.

Yeah, it's large.

How does this look for transforming my 10-speed Ridley Crosswind into a SSCX?

And the cranks are bodged, what's the cheapest option for a threaded 68mm bottom bracket shell?

Alfine cranks

Thanks, 39/18 or 39/16?

^^ where from.

I have some kicking around the parts bin. Can post or will be in London on Saturday

A 3/32" ss chain would make more sense. Most better ss cogs and rings are 3/32 should you upgrade to them later.

I though 1/8 on 3/32 cogs shouldn't be an issue and figured the stainless steel would be good to have on a cross bike.

Just extra weight and looser fitting, but it will work. No chains corrode before they wear out so stainless is only going to help if you don't intend to wash/lube your bike after races.

I though 1/8 on 3/32 cogs shouldn't be an issue.

It shouldn't be, but you do get some annoying creaking sound from the 1/8 chains moving about on the skinny cog/chainring.

Never had a rusty chain, come to think of it. Which of these would be my best bet? Z510 should be fine, or would a 10-speed be better?

Planet-X doesn't seem to stock the Alfine and I don't want to order at Rose because I don't like their stupid catalogues. How does this look for a crankset?

I'd run it with one of these: http://www.superstarcomponents.com/en/xcr-bb-mount-chainguide.htm

And should I get a Dura Ace, Ultegra or 105 BB? Price difference is minimal but I'm skint as all hell so wouldn't mind saving the money if it doesn't make a difference.

got 1/8 on 3/32 and I think that might be the reason i've dropped the chain a couple of times. Thats an issue as well.

10-speed + narrow wide front and rear ftw

^^^ get a 3/32" ss chain.

I don't think 10sp will work on many nice cogs. 8 or 9sp will.

Is a narrow-wide cog an existing thing?

You're not going to drop your chain on a SS tho.

You reckon!

Not trying hard enough ;-)

I'm sure I heard something about using a tensioner to keep it on...

Absolute black do a narrow wide cog

Pls don't tell @umop3pisdn to try harder. He's far too fast for my liking already!

The Doofer. Not a particularly good tensioner and certainly no guarantee of keeping your chain.

Not all tensioner setups are born equal.

...you really want all of the following;

Chainline
Chain-tension
Spring-tension
Chain-wrap
Tall tooth cogs and rings

So they do. Quite amazing looking things.
