Pinarello is synonymous with road racing and has supplied powerhouse teams with framesets over the decades. In doing so, it's enabled the brand the ability to work with the sport's top riders and receive feedback that ultimately fuels geometry and material progression allowing the firm to retain its technological superiority in the peloton and provide the pros with the best material possible to win races. Much like the evolution of the Dogma F8 into the F10, this all-new Dogma K10 Road Frameset is the evolution from the K8 and it's Pinarello's weapon of choice for the pros at Team Sky when tackling the cobbled classics and going as fast as possible over the pavé. It might lack the suspension of the K-S, but we would argue that visually, the seatstay cluster is drop-dead sexy, comfort is still a big priority, and it comes in lighter too. If you enjoy longer rides, a rougher parcours, and think of yourself as more of a classics specialist rather than a wispy climber or GT hopeful, this is your frameset.
Pinarello employs the same Torayca T1100 Dream Carbon with Nanoalloy composite used on the Dogma F10 for construction duties on the K10. There are no wasted grams so it'll be of help as you tackle days where the climbing is bordering on 5-digit numbers or it resembles a sawtooth profile full of short punchy climbs all day long. So why would you choose the K10 over the F10? That's a great question and we feel it ultimately boils down to geometry and tire clearance. The head tube angle is slightly more relaxed for more stability and it also offers a slightly longer wheelbase for more solidity when the pace is à bloc over bumpy sectors of road. The fork's rake is increased as well again contributing to the rangier wheelbase. The increase in rake does decrease the trail to bring a little quickness back to the steering so the handling never feels lazy. Tire clearance is up to 28mm from the F10's 25mm and in combination with the FlexStays, the comfort is heavenly. Again this frameset is purpose-built for longer fondo events over varying strada.
Pinarello's asymmetric design philosophy carries over to the K10 so areas of the frame that receive the bulk of the wattage transfer are beefed up to handle the forces while other areas see a reduction in material helping to save weight and improve the ride quality. We didn't detect any frame wag when we threw more coal on the fire and found that the frame's stiffness is very much on par with the Tour-winning and sprinter's favorite Dogma F10. It makes sense since it's a race bike after all and pro-worthy. The K10 also receives similar aerodynamic treatments, including the FlatBack shaping on the down tube, seat tube, and seat stays. The TwinForce seatclamp and aero post further cheat the wind and the 3XAir two-position waterbottle cage mounts, first seen of the F10, appear here too. Just up from the downtube cage are the provisions to mount the Di2 junction box for a clean look that again, improves aerodynamics. All of these sleek elements smooth the airflow so you get more speed with less effort letting you bank away some energy for a late race attack or to contest a small group finish that so often defines races like the cobbled classics.
So naturally the question arises, why would you choose the K10 and the K10-S? For most riding, the damper at the seatstay junction is a bit overkill. The K10's use of the tried-and-true monostay that Pinarello frames have long used thus relies upon the wider rubber, while on the S you’re getting 10mm of cushion to help smooth out even more road imperfections. We often feel that by having a damper on one end, it can give the bike an unbalanced feel front to rear and unless you're looking for maximum comfort or your roads are exceptionally pockmarked, we'd almost always reach for the non-S. It'd be hard not to address the difference in weight and Pinarello's claims that it's more responsive too. There's probably little chance of losing watts to suspension squish or the added potential of flex with additional joints, but the travel is also only 10mm so we'll just run the 28's a little lower and call it good.
Finally, the K10 has a feature that we've come to enjoy that's prevalent on every other Pinarello and that's the bottom bracket, in Italian threading of course. Threaded bottom brackets are much easier to maintain and install, and they virtually eliminate the dreaded creaking and popping associated with press-fit options. At the other frame opening, a tapered 1-1/2 to 1-1/8 head tube anchors your efforts while sprinting in the drops or during out of the saddle climbing on the hoods. Coming back down the mountain, the frame simply tracks without needing any weird body-English. Simply look where you want to go and the bike carves nails every apex with authority. Internal cable routing is happy to play with mechanical or electronic groups if your transferring parts or doing a dream build from the ground up and further aids in the aerodynamics department while keeping the frame's lines clean.
