Pro Bike Check: Sam Hill's Custom Nukeproof Pulse

View as: Slideshow | One Page

Downhill's favorite flat-pedal rider, Sam Hill, has a new Nukeproof Pulse DH bike with custom geometry. He rode the bike for the first time at Fort William last weekend and is getting more and more comfortable with every run. Sam felt the original Pulse geometry did not put him in a centered and balanced riding position for his particular riding style. Because the CRC / Paypal team runs aluminum Nukeproof frames, they are able to make subtle tweaks to geometry fairly easily and inexpensively. Listen to Sam and his long-time friend and mechanic, Jacy Shumilak discuss the tweaks to this World Cup steed.
