Spokes have populated the space around 1630 West University Avenue for 65 years, turning stoically as numerous bike shops have come and gone. The spot’s newest cycling incarnation, Chain Reaction Bike Shop, owes its staying power to owner Raleigh Faust and his staff of experts who cater to collegiate commuters, recreational cyclists, and serious athletes alike. Inside the unvarnished wooden storefront, rows of rides from Scott, Jamis Bicycles, and Surly await ownership. Every bike purchased at the shop comes with a lifetime of free service adjustments, making owning a bike as hassle-free as combing a hairless cat. Technicians see to these new rides, taking more than a dozen measurements for individualized fittingsand performing maintenance services that range from spot repairs to comprehensive tune-ups.
