The bug has bited. I upgraded the already useful dual pivot calipers on the Hammerhead to Ultegras today. I now have brakes that are either on or off.
It's quite exciting, skidding to a halt in front of old ladies with smoke coming off both tyres...
Don't talk to me about HH5's. My g/f, bored with me 'upgrading' the HH7, stole my Downtube yesterday. I'm down to two bikes again.........
