Affordable low weight and high tech: Culprit Roadi


While the weight issue regarding bicycles is a source of undisputed pride for those manufacturers who managed to keep the gram count down, the models benefiting from it may not always find themselves within hand’s reach for the majority of buyers. The same goes for recently developed technologies, for instance disc brakes on road bikes. But somehow, Culprit managed pull a rabbit out of its hat and presented Roadi, an alloy disc-brake road bike that might very well prove to be more than a match for its competitors out there.


This bike has been under development for well over a year and represents Culprit’s lowest priced adult race bike. This means it costs 1.575$*, and for the 8.14kg (17.95lbs.) it weighs it’s claimed by the manufacturer to be the best alloy gram to dollar bike on the market.

We don’t really fancy phrases that include „the most, best, or -est” here at Bike Advisor, so that’s a good reason to take a careful look at the specifications chart. The first thing we noticed is that despite the disc brakes and the 6061 alloy used, Roadi tips the scale at a claimed 8.14 kilograms, which, even if it’s off by a few tens of grams, remains competitive. We’d even go so far as to say it can challenge any other carbon road bike specified with the same Shimano 105 groupset it has, while keeping in mind that the other bikes feature mechanical rim brakes, significantly lighter. We would also bet on Roadi’s strength thanks to the 6061 triple butted alloy used, and also to the larger and thicker non-drive side chainstay and seatstay that has to face the extra loads generated by more powerful braking. Aerodynamics wasn’t left aside, the down and top tube featuring a cam tail profile, and the cable routing suits both types of drive system (electronical, only the Shimano Di2, and mechanical). The frame, with all hardware installed and painted, tip the scale at 1.310 grams.


As for the actual specifications, though the pictures ilustrate the bike with an older version of Shimano 105, Roadi, set to be released somewhere in autumn, will bear the newest generation of the groupset, the 5800 series. So, that means you’ll get an 11-speed cassette, a crankset compatible with both compact and standard chainrings, and a pair of levers that will work with Shimano’s state-of-the-art RS785 hydraulic disc brakes. And speaking of the brakes, the stock version of Roadi will feature TRP HY/RD calipers, that work with 160/140mm rotors (front/rear).

Culprit designed the Roadi having in mind a kind of road all-rounder in the sense that despite the race-orientated position, and short chainstay, the bike can provide some comfort by elevating the stem. We see the Roadi as a right candidate for upgrade, given its price, and frame, that is both light (unless you’re a weight weenie) and strong, but just as well as a good enough bike as it is if you don’t plan on riding billions of miles, so it kind of belongs to two different categories of riders in the same time, appealing to both through it’s price.


*The MSRP is USD 1575, and includes a multi tool and Culprit Cycling Jersey, but not including shipping from Taiwain and tax/import duties.
