Friendly and prompt customer service. I had a request to cut down my seat post and they handled it on the spot.
Chain Reaction has always been the most cyclist-centric bike shop around. And that includes all types of riders, not just racers.
Mike J is without a doubt the most customer service oriented person I have ever met. I have been doing business with these people for years and they are really helpful. For great service and a friendly attitude from a person who clearly loves what he does, you cannot beat this place.
Thorough, professional, friendly and excellent work
Service is stellar!
I trust that my business and bike is in good hands.
Bought my first bike with them. Very friendly and helpful staff. Makes you feel as if you have a friend helping you finding the right bike size configuration. I went back after 5 months for their free service offer and they honored it with pleasure even though offer was valid for 3 months. Highly recommeded.
Establishing relationships with customers by keeping records of people’s bikes and maintenances.
Great service, friendly staff and the best Trek inventory in the area.
I appreciate the service and information. And friendliness of the staff. I know that the bike is of good quality.
I appreciate doing business with a family-owned establishment. I like the variety of bike and accessories that you carry. I always get great customer service.
You are great at what you do and also are very nice people.
i will ask a question back.. What is there not to like?
answer: nothing.
I have bought my first serious bike from Chain Reaction over 30 years ago. I received great advice then, and I have continued to get great and honest advice on my purchases over the years. Also, the service is outstanding and the people in the shop listen and take their time to understand your needs. I still have that bike I purchased over 30 years ago!
Friendly experienced customer service, they take care of you especially on servicing your bike

Diverse selection, lots of seat upgrades available as well as clearance saddles. Also I was able to borrow an Allen wrench to swap out my old seat on the spot
Friendly helpful service, responsive.
super fast service and had the part I needed.
Friendly service. The shop people are so knowledgeable that they can answer any questions I ask. For this time, I purchased shift and brake cables. He (I'm sorry I forgot his name) provides multiple options and explained their pros and cons. That was greatly helpful for me to consider the balance between safety/performance and cost in choosing which ones to buy.
Steve and Mike are awesome. They pour their heart into everything they do. Truly, very hard to find friendly, professional, trust worthy business owners like them anywhere. Thank you Steve, Mike and all Chain Reaction Staff!
Best staff ever!

All I can say is: Support your local bike shop!
Chain Reaction has been my "go to" local bike shop for 29 years! I bought my first Gary Fisher mountain bike there in 1994, and have purchased seven bikes (and counting) from them in the years since. They are kind, friendly, helpful, and just good people. I recently purchased a new Trek Emonda 500 series road bike frame from the Trek online store as I like building my own bikes. The frame was delivered to Chain Reaction for pick up.
There was a delay, as well as an issue with the frame. Mike Jacoubowsky spoke to Trek directly. He told them that I was a long time customer, which resulted in Trek sending their top of the line Emonda 800 series frame to Chain Reaction again for me to pick up. Unbelievable, yes, but it's true, and I want to thank Mike for his efforts, and I now have a top of the line 2023 Trek Emonda. Thanks again Mike! Sincerely, Lewis Hughes long time customer.
