Swift Carbon Ultravox RS-1

Carrying the same blueprint as the range-topping Ultravox Ti, the second-in-line RS-1 is constructed from a slightly different combination of carbon, using high modulus T700 and T800 fibre.

While lighter and stiffer T1000 fibre is reserved for the Ti model, the RS-1's claimed weight of 1,050g for a small frame is far from shabby and its cheaper weave will save you in the region of £500 on a frameset, giving a £1,800 list price.

Side on, the stiff chainstays look beefy, but are actually slender enough to give sufficient room to run 25mm tyres. Another element of versatility is the frame's ability to take either a mechanical or electronic groupset and related cabling options.
