Cenna is a high-end shop for MTB, gravel, and road. There’s a level of personal service and care here from Cenna himself that doesn’t exist at the bread-and-butter shops in Boulder. I highly recommend this place for people who want to be treated like clients rather than customers. I’ve purchased several bikes, countless parts, and had tons of service/build work done here, and can recommend Cenna for all those things.

Awesome bike fit and great guy! After getting a poor bike fit locally I was on the search for a place that had Retul and could fit me correctly. Cenna was knowledgeable, helpful, and made adjustments to my bike that simply worked. I’m more comfortable and doing longer rides without discomfort - highly recommend for bike fitting!!

Cenna is the most knowledgable, thorough mechanic I have found in 20 years in Colorado. He is also the most honest salesperson I have met. Add to this his friendly, energetic personality, and I end up going a long way out of my way to work with him.

Very knowledgeable. Quality work. I won't take my Ripley any where else. This summer I broke my chain ring and I had stripped a bolt head on my crank. He dropped everything to get me back riding by end of day. He was able to drill out the bolt and had new cranks and a new chainring in stock. Better than best case scenario.

A fantastic local bike shop. I ordered a bike at Cenna's and I'm incredibly happy with the whole experience. Cenna took the time to get to know me and my riding style, he explained to me clearly how the ordering and build process would go down, and what to expect with timing. The bike arrived quickly, and Cenna built it for me and the way that I ride. His customer-centric approach is top-notch and precisely what I needed to feel confident in purchasing a mountain bike. No small investment these days. Cenna is very passionate and knowledgeable about cycling, and he enjoys communicating that knowledge to other riders. He's a down-to-earth guy as well. Thanks Cenna, I'm glad I drove up from North Denver!

I always enjoy the great service that Cenna provides. He fixed my shifting problem quickly. Looking around his shop at the bikes is good for me. Just amazing selection of quality bicycles.

I was having some discomfort in my right foot and stopped in to this shop after a ride. Cenna was knowledgeable and we had a fun conversation about tackling the problem. The store had all I needed in stock and picked up some insoles to improve comfort in the shoe. The insoles and cleat covers were installed without asking. Excellent customer service and I highly recommend this shop.

I was very much on the fence about buying a new mountain bike (mostly because I didn't know which to choose) and I had a rather low budget compared to the price of mountain bikes these days. After explaining my needs and budget to Cenna, he offered me a free demo on an Ibis Ripmo (which most shops will not offer free demos). I decided I liked the bike, so we discussed the aluminum frame, which was more in my budget. I went back and forth for a few weeks and Cenna was there to answer every question and concern that I had. I ended up buying the Ibis Ripmo AF and I love it. He took the time to explain pretty much everything about the bike and set it up for me. He has been wonderful every step of the way and I will continue to go to his shop for any service needs in the future. I recommend him to all of my bike friends.

This place is the real deal. Coolest bike shop I’ve ever been to. Cenna hooked up some good deals and got my bike out the door and ready to ride exactly when I wanted it. Customer service is next level and Cenna definitely knows what he is talking about. Get your next bike here, you won’t regret it.
