"Loved the Guru Dynamic Bike Fit. They really helped me get my bike and fit dialed in to the best position for me. Getting the bike fit, we were able to help fix a couple malpositions I didn’t know I had. I was having a knee kick-out during my ride that I was unknowingly doing because of hip issues. We ended up raising my saddle, pushed it back, lowered my handlebars, flipped my stem upside down, actually ended up replacing my handlebar and stem combo for a carbon handlebar cockpit, and replaced my 175mm crankarm Tiagra crankset for a 170mm Ultegra crankset. Thanks 40K Cycles, Mike, Charles, and any bike mechanic that helped out on my bike. -Jake"

"I have purchased a couple of bikes from 40K in the last 2 years and visited to window shop a few times. They are always so helpful and take their time to answer any questions you may have. The purchases themselves were quick and easy. Definitely my go to bike shop. Thanks again!"

"I recently purchased a Trek Domane 2 Al 2 disc from 40k cycles. The staff was incredibly helpful and knowledgeable. While working with the sales agent Mike he helped me get all the new riding gear I would need, and took the time to discuss all the pros and cons of each of the accessories. Once I had decided which bike to get they took special care to help with initial setup and talked through all the features of the bike with me. I will definitely be returning to 40k cycles for all my maintenance and future upgrades. 10/10 great experience and very pleased with my new bike. Keep up the great work!"

"Nearly a year ago, I visited 40K to take a look into getting a better mountain bike. Mike was very helpful in helping me find the best bike for my needs/wants. Fast forward many trails and adventures later… I popped a tube for the first time, so I headed back into the shop to drop off the bike for a repair. It was that SAME WEEK that I was back up and riding! Mike and the team at 40K are friendly, professional, and obviously efficient at their job. Thank you, 40K!"
