Trek Debuts Redesigned Speed Concept Bike


Fit on the previous Speed Concept was a hallmark, and that will continue with its new version. The Speed Concept's fit guide ascribes, as it did before, to arm pad and base bar stack and reach metrics. Trek again uses a size chart to determine the proper frame size and stem. Stem options will again include a low/near, low/far, medium/near, medium/far, high/near and high/far, providing over 14 centimeters of height adjust per size. Aero bar pad reach, pivot and extension will be nearly infinite as well.

The base bar has been moved forward by 4 mm and 10 mm of fore/aft adjust, resulting in 4-14 mm more knee clearance than prior. Conversely, and happily, the brake lever has been moved by 30 mm for easier reach and greater comfort, particularly while climbing.

Aero bar extensions will come in four iterations: s-bend, straight, ergo and short erg. Extensions can be shortened by cutting. Once fixed to the bike, the extensions have upwards of 40 mm of adjustment. The extensions are also set on a tilt cradle, allowing for pad/extension tilt upward for those that choose not to ride with the pads and extensions in a horizontal position.

Frame sizes are extra small (with 650c wheels), small, medium, large and extra large.

Seat posts are offered in 275 mm and 335 mm options. The 9-Series post is reversible, and will be made available in two versions: a standard 15 mm offset, and an extreme 50 mm offset version, providing a range from 74 to 82 degrees of effective seat angle. The 7-Series post will be reversible, and available in a 17 mm offset.

All told, while stack and reach remains the same, the pad fit range increases, providing for improved "lower" and "further forward" options than before.

Pricing and Availability

The Speed Concept 9.9 (stock color matte black/gloss black) with Shimano Dura-Ace di2 componentry and a Bontrager Aeolus 5 D3 carbon wheelset will price at $11,550.
