This bike was a Christmas purchase and was more of a racing bike than our son wanted. Brand new condition and rode once. Has been stored indoors and is in perfect condition. ***** When your kiddo is ready to get serious about racing, consider the mid-price yet high-value Redline Proline Junior. The Proline Junior is made with a Redline proprietary 6061 T6 alloy frame with integrated head tube, quality Euro bottom bracket, higher-end 3-piece cranks, and sealed hubs. The 100% chromoly steel butted and tapered race fork keeps the bike weight down, increasing performance and helping young riders maneuver the Proline Junior more easily. The Redline saddle/seat post combination also keeps it light and easy to use.
