Check out the photos in my gallery. I have turned my brake lever sideways and use my thumb to activate the brake. I have not put it to a real test yet as I have been sick and not able to ride. I have tried it out by just sitting on it and pedalling in my underground parking lot. It feels pretty natural. The ultimate test will be when I go to the Cali. Muni weekend in September. I should be getting the leather cover from Roger Davies soon. I got the carbon base from Darren Bedford.
