All bicycles sold at REI include a free warranty tune-up. New bikes go through a normal break-in period, after which readjustment is important for longevity and performance. 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.

Rated 2 out of 5 by from Rear Brake Flaw Unfortunately I can't give a review of the bike's performance yet because there was a clearance issue with the Promax rear disc brake. the location for the cable connection sticks out where the foot travels when you pedal. I went back to the store to see how the brakes were on other bikes. All of the ones equipped w/ different brand brakes had the caliper/cable connection either directly over the chain stay, or in between the chain stay& no clearance issues at all. the only option I was given to make that bike work was to buy a new rear brake (which obviously I am not happy about) seeing as how you will be paying an extra$100 anyway, I suggest you just buy the 105 Synapse as that comes equipped w/ the better designed TRP disc brake and you get all of the other upgraded components.

Does the bike have eyelets for rack or fender mounts?

Asked by: Nsp1
This bike does not have braze-ons on the seat stays, but there are cargo racks that allow you to connect around the seatpost or seat tube.
