BIKES - IMPULSE P21


Impulse P21

Price: £499.99


On first inspection, the Impulse P21 is a refined and elegant city bike, with all the fittings, including fenders, rack, chainguard and even a single shifter that controls all 21 gears. But lurking underneath this civilized exterior is a performance bike that's ready for hard and fast weekend rides or heavy touring. The key is the SRAM DualDrive drivetrain that serves up 21 widely spaced gears - enough for just about any type of terrain. The SuperLite 4130 chromoly frame is extremely stiff for excellent power transfer, but just compliant enough. The Kinetix Aero rims and Schwalbe Marathon Slick tires provide rocket-like acceleration. If you want one bike for all different kinds of riding, the Impulse P21 deserves a serious look.
