bicycles made by hand

OBRIEN "RNA" complete bicycles

Complete and ready-to-ride except for pedals; includes FSA bars, stem, seatpost and Chris King wheelset. Other component combinations available on request.

We have another new standard called flat mount for attaching the brake calipers to the frame. At this point, the fitment I've developed is superior. And after three standards over the last six years, I’m going with my configuration. I'll do a wait-and-see if the flat mount sticks. (click on image to the left)

New kits are prepared for your perusal. Greg Louie has provided another advanced design with new colors and graphics to enhance your OBrien ride with comfort and visibility. Not just a knock-off of a trade team kit. They are made by Voler in California from super breathable fabrics with a nice chamois; the cut is "race" fit so they are tighter than usual - size up if you want a relaxed fit. The clothes are made to order and they ship in about a week after you place the order on their website: Voler OBrien kits
