Spotted...

Must have been a forumenger on what looked like a titanium custom fixeh with carbon forks.
Westbound 8pm last night at Sheen Lane / Upper Richmond Road executed a nice track stand.
Also remained extremely calm when he shifted well into primary and slowed to be more visible to a car about to pull out only to be under-taken by a muppet roadie.
You casually upped the cadence and cruised back past the muppet, without so much as a backward scowl.
Chapeau.

Custom Ti fixed - check.
Heading west - check.
Primary position - check.

Sounds like DJ, but remaining calm to an idiot on the road is quite out of character.
