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. Because that's exactly what we look for in our own gear too.
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.
