Back at Sea Otter, we saw the prototype for the Cortina T3 CX Pro cyclocross bike from Marin, but now it’s officially unveiled and on the market, and Marin has also stepped up and sponsored Elite ’crosser Nicole Duke.
“The Cortina goes carbon, finally,” said Mark Vanek, the Product and Marketing Manager who was heavily involved with the making of the bike. “It’s been in the lineup since 1999, in different iterations, as aluminum.” (See our profile of the 2012 aluminum model here).
They use a T3 tube to tube–construction, which Vanek said, “Really allowed us to be creative tuning ride quality and creating a bike that’s a pretty optimal weight for stiffness and reliability.” The seat tube has a larger diameter at the bottom near the bottom bracket for stiffness, but it tapers for a fit of a 27.2mm seatpost. “We want the top end of the bike to be super compliant,” Vanek explained.
The cable routing is set up for internal routing of either electronic wires or mechanical cables. “It allows the rider to set up the bike with electronic or internal mechanical, or if you want to run full-length housing internally, you can do that as well.” And for the Di2 users, the battery will be internally seatpost mounted, which is charged at the front junction box under the stem, so riders won’t have to remove the seatpost.
“We wanted to make the bike a little more competitive, weight-wise, for racers. We’re going to do two models, a top-tier level and then a bullet-point spec, blue collar version as well.” The Cortina bikes will be in stock soon. The MSRP is $5500 for the T3 CX Pro, but for the budget-conscious, there’s also a model with the same frame but a Rival group available with TRP ‘s dual-piston Spyre brakes for $2700.
