Saw MattH this morning, no other commuter, that I see, is on Tri bars. I was caught in Bagshot by another commuter and then drafted him the whole way to Frimley. I simply can't drive the cadence required to keep that pace (23mph/125rpm) on the front but can spin it when tucked in behind.
MattH, advice from a local: When travelling into London, at the end of the A30 Egham bypass (dual carriageway past the Ferrari garage) take the third exit and go through Staines town centre rather than the A30 bypass. Turning left over staines bridge and later through the pedestrianised bit of town. This saves crossing the 5 lanes of traffic, including those exiting the M25 into the righthand two lanes, to do the right turn onto the A30 at the middle of the Staines Bypass. On the way oout of London the Staines bypass is fine though the drivers will not expect you to be on the 270 deg decending spiral at the Egham end.
