An endurance road bike keeps road speed but puts you in a more upright position and takes wider tyres. IKUISTA builds one: Spektri, an endurance and all-road bike for long days and imperfect surfaces.
Complete builds start from 8.1 kg depending on size and configuration. Tyre clearance runs to 45 mm. Run 28 to 32 mm for pure road riding, or 35 to 40 mm when the route includes gravel. Drivetrains run from Shimano 105 Di2 up to GRX 800 Di2, or SRAM Rival, Force and XPLR AXS.
Standard parts, not proprietary ones
Spektri uses a UDH derailleur hanger, a threaded bottom bracket and an ordinary headset. Nothing on the bike is specific to us, so any well-stocked bike shop in Europe can service it and you are not tied to one supplier for spares.
Bought direct from the workshop
Each bike is assembled and inspected by hand in Tampere, Finland. There is no dealer margin in the price. The frame carries a two-year structural warranty, five years once you register the bike, and ten years with the paid Extended Warranty.
If you are still choosing
Spektri sits between a race bike and a gravel bike. If you want maximum speed on good roads, look at Vektori or Fluxi. If most of your riding is on gravel, look at Halo.
