I'm Troy Tritschler, an outdoor enthusiast that has worked in the cycling and outdoor equipment field for 30+ years.

New Location

"I first met Troy when he was an associate at Summit Canyon Sports in 2008. I found him to be very knowledgeable and helpful in outfitting me for backcountry skiing. Through the years I have relied upon him for his knowledge and fine workmanship in purchasing and maintaining my outdoor equipment (Mountain biking, skiing,). I am so glad he has opened his own shop in New Castle and will continue to rely on his knowledge, mechanical ability, and friendship. Forgot to mention; He's a super nice guy!"
