Description from BikeRadar 10/19/18

The Logic, and its stablemates, are a celebration of those heady 80s days, and while no longer made in Ritchey’s American homeland, the Road Logic is still meticulously put together, hand-crafted with some serious skill in Taiwan. 

With details such as the forged and machined head-tube, which shaves more than 80g from a standard headset/head-tube design, beautifully controlled welds and signature encapsulated Ritchey dropouts, this is a bike built with serious frame-building pedigree.

In the past the Road Logic has been a frameset-only option, so you’d either build it yourself or get your local shop to build it to your specification. For 2018, it is being offered as a complete bike, with Ritchey finishing kit and Shimano 105, all for a decent price.

The Ritchey components come from the company’s affordable Comp range, and are all very well-designed. The 4-Axis stem is designed to evenly spread pressure, making it harder to overtighten and damage the bar, and the curve shaping of the bar is one of the very best anatomic compact designs around. 

The slender Skyline saddle is well padded and the shape suited most of BikeRadar’s testers. Ritchey’s saddles can often be overlooked in favour of the big name brands, but if the Skyline is anything to go by they are worth checking out.

The Zeta wheels have a decent profile and are wide enough at 17mm internally to make a very good match for the 27mm Tom Slick tyres. The name suggest that these are fully smooth road rubber but actually have deep and defined sipes running from the centre to the flanks of the sidewalls. The deep, soft compound grips tenaciously and they run smooth, but don’t feel as rapid as the lightest race tyres around.

The Shimano 105 drivetrain performs superbly, and Ritchey hasn’t deviated from the group so the Road Logic has far superior stoppers than its rim-braked rivals.
