BLB Viper Singlespeed Frameset - 2021 - army green

BLB Viper Singlespeed Frameset - 2021 - army green

The BLB Viper frame is the result of all that experience designing and riding steel and aluminum track frames - an embodiment of evolution. Made from 6061 alloy, the Viper launches out of the gates and continues the attack through the corners of the course.

The tapered carbon fork keeps you on track, whether through switchbacks or fighting through busy city traffic.

The integrated seatpost keeps weight down while increasing stiffness - stiffness that carries down into a burly bottom bracket shell, transferring the power to explosive sprints and summit killing climbs.

Depending on your preference the integrated seatpost can be cut and an appropriate seat clamp is included.
