Great E-Bike service. Thank you.
We love the local, family atmosphere coupled with high technical proficiency as well as the really great selection of Trek bikes. Chain Reaction staff are always great to deal with, very fair, and a lot of fun. The very personalized service has drawn us back to Chain Reaction for more than a decade of bike purchases, tune-ups, and repairs for our whole family.
Meticulous attention to detail while fitting me for a new bike.
I come for the advice. I appreciate the store mom jumping in and encouraging the new red haired guy to try to find the parts to my pump rather than saying it’s not worth it. (sorry i don’t know anyone’s names). Definitely wanted to say his first thought about “it’s probably not worth it” was not what i came into the store looking for. I brought the pump in to try to fix it, and would have bought a new pump if it was unfixable, but i wanted to try.
in the end we found a new head at the end of the pump which fit nicely on top of pump. after i got home, i was kicking myself for not trying to replace the spring inside the valve, which might have fixed it even easier. but im very happy with my new pump head thing.
Really, the reason why I keep coming back with my old equipment is that yall give consistently good advice and like trying to solve my problems. That good service made me happy to eventually buy my new bike from ya’ll, even though i know i could get a cheaper one from craigslist. Keep training that guy so he doesn’t give up on the problem at hand so easy.
Just want to shout out the great service. They went above and beyond to take care of me, thank you guys so much!

Very friendly and helpful each time I visit.
Mike did a great job getting my bent derailleur and hanger working.
Great knowledge & Great customer service (both sales and repairs). Over many years we have bought 8 bikes from Mike and Steve (co-owners of Chain Reactions), six for us and two for friends. If you purchase a bike from CR, routine maintenance, e.g., cable adjustments, will be done for free for the original owner.
good job
You provide the definition of "personal service". We always get the honest and best advice on everything from new products to ongoing bike maintenance. We can't thank you enough...and we always recommend you first when asked by friends where they should go!

Very helpful & willing to explain things.
Good but spendy
We had great service from Kevin. He helped us pick out a bike for my son, and got all the accessories we needed as well & put them on his new bike. Thank you!
As always, very knowledgeable advice from Mike, fast service, fair price.
Always a pleasure dealing with Mike and his staff
I loved your warm professional service that took care of my bike repair. Very very impressive.Peace, Larry Purcell Catholic Worker
My bike rides just great now that the team tuned it up. Smooth as silk,
Very friendly and helpful. I took my grandkids to get a bike and they were very good with them, helped me pick out a better fitting bike than the one I was thinking.
Steve does an amazing job of getting the fit just right.
Thanks for the attention to detail .
Chain reaction has been our go to bike shop.
We have 6 bicycles, they know our bikes. We recently went on a 1200 mile bike packing tour in Europe. They checked our bikes- no mechanical problems we encountered. Only 3 flat tires total.
It’s good to have someone who knows your bike.
Super nice team. Fast turn around. They were able to fix my daughter’s bike!
My family has been into Chain Reaction 4 times in the last week. We got sized for a new bike & then went back to ride it out of the store. Kevin and Becky were helpful as always -providing excellent service and advice. I brought my Domaine in for a chain replacement & new rear tire. I also needed a new cassette. I was very pleased to get my bike back the next day. They know I usually ride on a daily basis !
We have been customers for close to 30 years & always feel like family. We’ll continue to shop locally at their shop.
Personal service, responsive, quick turnaround. I had not brought my bike in for the 30-day checkup and they did it many months later.
Knowledgeable, honest staff
Excellent store with great mechanics and support

I have purchased 3 Trek road bikes from Chain Reaction over the past 16 years. When I first started with Chain Reaction, they were located in Los Altos which was somewhat conveniently located since I live in San Jose. Since they are now located only in Redwood City it is less than convenient to get to their shop. Why do I continue to continue with this relationship - trust, quality of service, knowledge, quality inventory. They have always had a fantastic selection of anything I am in the market for which might be a large purchase such as a bike or something trivia like a tube. They stand behind what they sell so if there is a problem, they take care of it. Everyone who works there is very knowledgeable and I have always felt very comfortable asking questions. Service has always been outstanding.
