It costs a lot of to invest in a time trial-specific bike—and aluminum frame-only options are uncommon. This is what makes the 2011 Kinesis 415 TT frameset an outstanding item on the market. Kinesis is well-known with a reputation for its quality machines and its 415 frameset is just a perfect example.
One of the latest feature of the 2011 Kinesis 415 TT frameset is the SPF (superplastic formed) tubing in its front triangle. Kinesis combines aero profiling with thin wall, lightweight tubing through its SPF feature.
With a decent width, the SPF top tube meets the head tube, making it super stiff and narrows down towards the deep aero section seat tube. Also, its seat tube enjoys a lot of benefits from the new SPF technology, which allows it to hug the wheel more closely than the KT-410 frame.
The teardrop section of 2011 Kinesis 415 TT frameset down tube is enhanced, allowing it to meet the bottom bracket. Chain stays are made stiffer, lightweight, and alloy. Aside from the carbon seatstays, the 415 frame features a carbon aero seatpost, an Energy fork and headset.
