All of our bike prices include pro-assembly.
One of our highly experienced pro-bike specialist mechanics will build your bike, then test ride it in the parking lot to verify everything works flawlessly. We will then remove the rear wheel, seat post, and front stem plate for shipping. Your bike will be packed for shipment in a manner that fully eliminates any possibility of arriving to you in less than perfect condition. Once you have your new bike, simply install the front wheel, slide in the seat-post/seat, and attach the stem front plate. You will be ready to ride or race in minutes.
The selection of the correct size frame (and stem, bars, cranks, etc.) is a crucial aspect of the road-bike buying experience.
We will contact you once you have placed your order to discuss and verify the sizes of each item that you need. Once you receive your new bike, ride it for a week or two and verify that you are comfortable with your chosen stem length, bar width, and crank length. If not, you may exchange any of these items for another size, as long as they are returned in as-new condition. (As-new, meaning: unblemished in any way other than bar-tape residue, pedal installation marks on the cranks, etc.) We will then rush you the size that you desire of the item, and sell the returned item as a test-ridden item at our retail store. If desired, we will provide a full comprehensive bike fitting free with any bike purchase. We work with the sizing system from of our favorite full-custom frame builder, Moots. Just go to moots.com and print out their highly comprehensive sizing questionnaire (with very detailed, easy-to-use instructions and pictures.) You will then be contacted by one of our in-house sizing specialists. We welcome all of your questions on any and all aspects of the sizing process when you are purchasing a frame or bike from us!
