Salsa Cycles will have a Demo day at Endless Cycles on Thursday, August 7! Rides will start just after Noon, ending at 7:00 PM.

2015 bikes will be represented - models and sizes as follows:

Spearfish Carbon, XS - XL sizes.
Horsethief Carbon, S - XL sizes
Bucksaw Full-Suspension Fatbike, S - XL sizes
Mukluk Front Suspension Fatbike, S - XL sizes
Beargrease Carbon Fatbike, S - XL sizes
Blackbarow 5"-tired Fatbike, M & L sizes

Rides are a first-come-first-served basis, so if you want a day to play hooky, this might be a good one! We ask that rides stay under 1-1/2 hours so people can get a chance to try a bike, but that would let you get in a decent loop on local trails.
