Santa Cruz Heckler SL Carbon C GX AXS

Regular price£8,799.00
VAT included.

Lightweight and surprisingly powerful, the Heckler SL gives you the best of both worlds with power assistance to let you ride further and faster than before while still handling more like your regular trail bike than a full power e-bike on the way back down. 

A Fazua Ride 60 drive unit is at the heart of the Heckler SL. 60Nm of torque and peak power of 450W takes the sting out of the climbs, but the motor sips power, meaning the Heckler SL gets a similar range from its 430Wh battery as a full power e-bike. Three customisable power modes let you choose your level of assistance and, via the Fazua app, you can modify each mode to prioritise either power or range. 

Riding on MX wheels with 150mm of rear travel and a 160mm fork, versatility is the name of the game with the Heckler SL. Slack geometry and just enough travel lets you push the limits on the enduro trails of the Golfie and still be able to pump and flow your way around mellower terrain. Think of it like a Bronson that climbs faster.

    Why Choose Us?

    At The Heart Of The Trails

    Based on Innerleithen High Street in the Tweed Valley our shop lies  in the shadows of the infamous Golfie. An Enduro World Series venue and legendary in the UK mountain bike scene as one of the most prolific and exciting mountains to ride in the UK.  The Tweed Valley and the 100+ km of trails that stretch out from our front door have proven to become a meca for gravel, MTB and road cycling  and our staff are out, rain or shine experiencing it all. We're set up to provide you the best advice and select the products to stock that are the best value, best to ride, most eco friendly and will last you the longest out on the trail.

    From Riding to Retail

    Our business began as Dirt School in 2006, a mountain bike coaching company set up to deliver the best learning and support a mountain biker could ever want. From World championship wins to the award winning BASE college course, we've experienced and forged it all. Our evolution led to the formation of Tweed Valley Guides and now Tweed Valley Bikes too, allowing us to help you buy the right equipment, and be able to ride with you on the best trails and help you learn how to get the most out of it. Our shop has genuinely grown from the trail.
