PROTO – 3.5″ Sentinel SCS (Silver) Scooter Clamp
PROTO – 3.5″ Sentinel SCS (Silver) Scooter Clamp
The PROTO Sentinel SCS is a silver-colored scooter clamp that is the next generation of Standard Compression System (SCS). It is 3.5" tall and offers 2" of handlebar support, which is over 30% more than a 3" SCS. It features larger 8mm bolts with 6mm allen drives and an offset slot that provides 25% more threads for increased torque and decreased chance of stripping. It is tapered at the top and base and has two cutouts that remove unnecessary material and weight, making it lighter despite being half an inch taller. It also includes a new feature called the Spreader-Bolt, which can be used to open the clamp for easy installation and removal without the need for the "penny trick." The SCS logo is placed in the center of a crown of thorns representing enlightenment and salvation from the past, symbolizing the Sentinel's role in guarding the future of scooter design. This product was designed and manufactured by riders in San Diego, California, where PROTO is known for its innovative approach to product development and design.
Finding the right size bicycle is important for a comfortable and enjoyable ride. There are various frame sizes available that are designed to fit riders of different heights, as well as different wheel sizes and frame styles. To choose the best fit, you can look at the sizing and geometry chart provided by the manufacturer. This will show you the seat tube length and top tube length, which can affect the stand-over clearance and comfort of the bike. You want to aim for a comfortable position that isn't too cramped or stretched out. If you have any questions about finding the right size bike for you, our team of experts is always happy to help.
