We define color as the main color of the item. It may have accents or highlights in other colors.
Weight
In Store products are available to view in our showroom. In Store orders usually ship the same or next business day.
These models are available for online purchasing and can be shipped directly to you.
The seatpost diameter must match to the seat tube diamater of your frame. If replacing a seatpost, you can usually find this measurement etched near the bottom of your current post.
Seatpost length is measured in millimeters. It is typically measured from the bottom of the post to the center of the rail mount.
Offset is often referred to as setback. This is the distance in mm that the clamp is offset from the center of the seatpost.
Seatpost Material
Rigid seatposts are the most common type of seatpost with no suspension or dropping capability.
Seatpost Clamp Style
Clearance items can save you big.
Bar clamp diameter is the diamater of the handlebar.
Stem length is measured from the center of one clamp to the center of the other clamp. This measurement is sometimes known as the reach or extension.
S.H.I.S clamp diameter is the steerer tube diameter.
Stem angles are measured perpendicular to the clamp. For example, a 90 degree stem is straight. Sometimes, this may also be refered to as a 0 degree stem. If two measurements are listed, the stem can be flipped for angling up or down.
