Not bought a new off the shelf bike for 10+ years either!
Very excited.

Sorry, a TI Brompton??
😆
Goodness
Gracious
Me.
What did you choose the Roubaix over?
Take it you only had the choice of the brands your shop stocks?

Moaning about customers.
Can you fix a Ti fork with a wooden salad spoon?
Jealous, btw
A TI Brompton? - that is the ultimate niche bike and i salute/doff my cap to you - impeccable taste!.
Dunno bout the roubaix though...........?
😉
Rubbucks' are ace. Good call.
R.E. The Brompton - you know they are launching a 17.5" wheel version next year?
😉
Good stuff - have you found Bromptonification yet?

Tarmac, Venge and Wilier/Cannondale/Giant. We get a better discount with SBC, and the Tarmac and Venge were too harsh (and aero apart, no faster I believe), it's ultimately going to be a general purpose road bike although it'll get used for tri's for a while.
I'd always thought the ti Brompton to be a waste of £, but I'll own this forever I think, and lugging it around means weight matters more than any other bike.
Ben - not yet, I fear that could be a time-hoover! I do want to get my 2 x 3 deraileur set-up working, still struggling to sort it out, looks like I'll have to grind the outer lip of an 11T. Should save 1lb though I think, though ratios will echo the Sram 6 speed and not the BWR. I wonder if it's been done before.
I do of course have my own idea for a folding bike, made of carbon. If I ever get my DIY finished, a wooden proto will be made!
Wooooo, niche carbon foldie...
Neat, keep us informed 😉
You're doing the 3 at the back with the Brompton derailleur? No, I've not seen that done before.
Wooh. A first.
If I ever CBA doing it...
How big do you go sprocket-wise with your conversions Ben?
A Brompton? We aren't friends anymore.
i was chasing a guy on a brompton this morning, he mustve been on a Ti one, coz its the only way he could outpace me! 😉

I use a 20t on the Sturmey 8-speed hub, that's a different chainline to standard, though, and it's a very tight fit especially on a titanium frame - they're not built to the same tolerances.
Luke, had one for months! You'll see the light one day.
Ben I've read that a 19T will go in the frame OK, and if I limit myself to that then I need the 11T to get the jumps right.
It all depends on the chain line - the problem is interference with the chainstay which tapers inwards a lot.
OK that shouldn't be an issue, but what about limits imposed by the tensioner?
On my earlier 8-speed kits I used the 2-speed tensioner with spacers to alter the chain line - it was okay, though I have a better way now.
No I meant does the tensioner not limit the largest cog you can fit - IIRC you lengthen yours for this reason?
Yeah, that's what I meant too 😉
The 2-speed tensioner has the top cog further away from the axle, so it can accommodate larger sprockets - though I might have been using 19t cogs on the X-RF8 back then, not the 20t on the X-RF8(W).
The single-speed tensioner has the top cog closer in so I have to modify it.
So what's the biggest cog on a 2s?
Well I was definitely using 19t, maybe 20t.
