BLB Viper Frameset - Polished

Free shipping Free shipping

All our experience designing and riding steel and alloy track frames has culminated in the birth of the BLB Viper - an embodiment of evolution.

Crafted from 6061 double butted aluminium, the Viper will launch from the gates and continue the attack through the corners of the course - the 35mm tapered fork ensures you stay on track wheter fighting through switchbacks or busy city traffic.

The integrated seat post keeps weight down while increasing rigidity - rigidity that extends downwards into a burly BB shell, transferring 100% of your power to explosive sprints and summit killing climbs.
