Serotta CSI

Makes sense any particular reason for the Nemesis? Because they've got an established rep?

Are you tempted by something a bit wider if you're trying to go for a bigger tyre? Or does it not make the same difference to tyre profile as with clinchers?

EDIT: Just realised that they're 21mm so probably the Goldie Locks of tub width [guessing].

The width, and the weight, while being a solid eyelited construction.

Where do you purchase FMB from Andy?

Not cheap.

I'm thinking of these for Styrkeprøven. Not saying they're well suited for it. Just that its the only time I'll do anything that'll justify such a high end tyre.
