"Every year bikes change, styles and trends evolve, old bikes are in need of repairs and new bikes are waiting for that personal touch. We provide the means to keep your bike on the road and fun to ride!"
Thomson is leading with innovative design for two primary markets - aerospace and cycling.
"Ritchey bicycle components have been raced to victory in some of the biggest cycling competitions in the world including the UCI World Championships, the Tour de France and the Olympics and it all began in a simple garage in Menlo Park, California with Tom Ritchey.'
"We move forward with a desire to deliver the best possible components to our customers and a determined spirit of competition."
"At Salsa, we believe a sense of adventure makes life better. The bicycle can be so much more than just a bike; it's a path to new places, new people, and amazing experiences."
Dimension makes quality components to repair or custom-fit the vast majority of bikes being ridden today, and provide the accessories that make them fun to ride.
"Whisky Parts Co. makes high quality carbon components designed with unique features that help you do more with your bike and stand out from the rest. We believe that our work can help every rider find a new level of confidence and performance with our sturdy and lightweight forks, bars, rims and more. So whether you are building a new bike or upgrading one you already have, you'll find an uncommon attention to detail in every product we offer."
"Simplicity is the hardest design principle to follow; It's at the heart of our approach to eclat."
"Whether getting faster requires lighter components, components to give you greater control, or something else, Tioga will keep tweaking and innovating to find it."
"W-T-P have always taken a lot of pride in ourselves and in building bikes that are capable of taking everything a rider throws at them. We are constantly at the forefront of developing and manufacturing materials that will with stand hard and furious riding and our designs are made to combat common breaks and bends."

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.
Rigid seatposts are the most common type of seatpost with no suspension or dropping capability.
