Low Friction Bottom Bracket Designed so that the bearings rest on the axle of the crank, these BBs provide a straight load to the bearings, which means your BB will last longer. This also allows us to make the Prime Threaded BB with tighter tolerances, so it runs smoother with less friction. This means you'll require less effort to make it up that hill or sprint for the line. To keep our Threaded BB running smoother for longer, we use special seals that keep water out of the bearings. We use multiple smaller seals, which reduces friction and provides a better barrier against moisture and dirt. Our bearings themselves are manufactured to precision and packed with slick, waterproof grease. Ceramic Bearings With our ceramic bearing option, friction is reduced meaning less energy is required to turn the cranks, they're also more durable, and don’t rust so they'll require less maintenance. If you're a rider seeking out every possible advantage over the competition, the ceramic option can help take your performance to the next level.

Water Repellent To make our BB86 Bottom Bracket even more durable, we've used special seals, which keep moisture out while keeping drag to a minimum.

Developed to keep you supported over long distances and many hours on your road bike, this endurance-focused saddle comes equipped with a waterproof microfibre cover for reliable performance in all-weather conditions. Prime has also kitted out this model with a nylon fibre base, which ensures maximum stiffness and strength without adding any unnecessary excess grams to your ride. Another highlight is its titanium alloy rails which provide a secure hold to your seatpost, while its chromium nitride (CrN) coating delivers additional wear resistance and protection against corrosion. Endurance Road Saddle with Titanium Alloy Rails The Prime Doyenne Endurance saddle features titanium alloy rails coated with chromium nitride (CrN). These offer exceptional tensile strength, stiffness and corrosion resistance at an extremely low weight. The reduced weight helps you conserve energy as you climb and accelerate, and ultimately saves crucial seconds on your time. Crn/Ti rails are also highly resistant to flexing and deforming. This makes them far less likely to bend or creak as you ride. The seat rails also feature measurement markers, which help you adjust the fore/aft position of your saddle accurately to achieve an efficient and ergonomic pedalling stance. Prime Saddle Integration (PSI) PSI allows you to clip PSI accessories into the saddle base to allow for sleek integration.
If you're looking for style and function, look no further than the Prime Carbon Bottle Cage. It’s stiff enough to handle fully laden bidons, and yet offers enough flex for quick and easy removal. Please Note: mounting bolts supplied separately.
