The tailoring of any bike is an important step in the long term enjoyment of riding and it can take time to adjust to the fit of a new bike. All contact points (pedals, shoes, and saddle) can be changed and altered for personal preference, performance, and comfort.

Condition Rating Guide

Our experts inspect each bike and rate its components on a scale of 1-10. The condition chart’s Overall Rating is the average of those individual components, helping you tell how much overall wear a bike has. We don’t sell anything that scores below a 7. Along with the condition chart, look closely at the bike’s detail images, which highlight any wear or damage.

10/10 Like-New:

These bicycles are good as new, often built right out of the box from the manufacturer. Original stickers, parts, and accessories are included. The frame and wheels might have minor blemishes or scuffs from transportation or showroom display. Drivetrain, levers, cockpit, and suspension (where applicable) are in new condition.

9/10 Excellent

While these bikes have been ridden, they remain in excellent condition. Frame and wheels show slight signs of wear with only minor scuffs and scratches — no paint chipping. The drivetrain shows light wear but the derailleurs, shifters, and levers have not sustained any damage. The cockpit has light wear, primarily on the grips or handlebar tape. Bikes with suspension components have minor scuffs and scratches on the fork legs and shock, and the stanchions are immaculate.

8/10 Very good

To earn a rating in this range, bicycles have sustained some wear but no significant damage. The frame will have slight paint loss, scratches, and/or scuffs. Wheels will also have minor cosmetic damage on rims, spokes, and/or hubs. The drivetrain will have wear from normal usage and there will be slight scratches and scuffs on derailleurs, shifters, and levers. Cockpit, saddle, and suspension lowers (where applicable) will also have cosmetic scuffs and scratches.

7/10 Good

Bikes in this range are well-loved and have moderate wear. While the frame and wheels will have cosmetic scuffs, scratches, and/or paint loss, they will not be structurally damaged. Aluminum, steel, and titanium frames may have minor dents. Carbon frames may have been previously damaged, but have been professionally repaired and are structurally sound. Aluminum rims may have minor dents. The drivetrain has moderate to heavy wear. Handlebars, stem, derailleurs, and levers show moderate scuffing or scratches, and the saddle might have slight tears. If the bike has suspension, those components will have scratches and scuffs. The stanchions may have small scratches.

6-1/10 Average

We do not sell bikes that we rate lower than 6 on the condition scale. For example, this includes bikes with major dents, carbon fiber damage, excessive drivetrain wear, and/or moderate to significant suspension component wear.
