Bring your new bike in to your local REI for its free tune-up within 20 hours of use or 6 months from purchase, whichever comes first. Contact your nearest REI bike shop to schedule this important service.

What is the weight of the 56cm Century 4 Carbon disc and how large of tires will it fit? Thanks for the answers.

Asked by: Year Round Biker
Unfortunately, Diamondback does not provide us with the weights of their bikes. There is no industry standard for uniformly measuring the weight of bicycles. Frame size, componentry and where or not certain accessories (reflectors, racks or pedals) are included with the bike can cause a significant variance in bike weight. This bike will fit a 32mm tire, and possibly larger depending on brand.

You list a weight for the bike in the spec. Where did you get that information? Does that come from Diamondback?

Asked by: clarkide1281
We received the bike weight directly from Diamondback.
