Center Alignment Design (CAD)
Through Strummer Center Alignment Design (CAD), our headset & bottom bracket answer the needs of cyclists.
Strummer bottom bracket with CAD system increases stiffness and pedaling efficiency by balancing the left and right sides of the BB. This also helps frames that are not manufactured perfectly.
The Strummer Headset improves cycling performance by eliminating clamping on the axle fork that are not needed, without reducing performance.
Tubeless Straight Side (TSS)
Commonly called hookless, this rim has a shape that is specifically designed for tubeless. This rim cannot be installed with clincher tires. Tubeless Straight Side (TSS) is a development of the previous system, namely Tubeless Ready System (TRS).
Rims with this technology are lighter in weight, produce a rounder tire shape after installation (thus having better characteristics when riding), and have a higher volume for the same outer width (thus lowering tire pressure, increasing tire grip, and improving comfort).
Tubeless Ready System (TRS)
This is a rim that is commonly referred to as "Tubeless". The advantage of this rim is the flexibility it provides to the cyclist. This rim can be installed with a tubeless system after installing the appropriate tubeless rim tape on the bike.
If you don't want to use tubeless tires, users can also use tires with a clincher system. One of the advantages of the tubeless system is lower rolling resistance.
Integrated Cable Routing (ICR)
A system for tidying up cables to improve neatness and aerodynamics on the bike. Headsets with the ICR Strummer system allow you to change bikes that previously used an external cable system to an internal one. The Strummer ICR Headset also prevents water from entering the system by using rubber seals in strategic areas.
Offset Spoke Hole (OSH)
Strummer rims with offset (off-center) spoke holes increase the strength of the assembled wheelset. The inclination and tension of the spokes on the left and right sides of the wheelset can be set more evenly.
Hidden Fork Riser (HFR)
The solution for steerer tubes on bicycle forks that have been cut too short. The HFR Strummer system allows cyclists to safely raise the stem mounting location. This fork riser can be safely installed on carbon, aluminum, and steel forks.
Ultralight Technology
Strummer Sprocket with Ultralight technology uses AL7075-T6 material on the large gear to significantly reduce weight. On the small gear, steel material is still used to provide strength at frequently used ratios.
Superdura Technology
The Superdura Strummer sprocket is the best sprocket we can make today. Using modern technology and materials, the CNC machining process is further advanced. The materials used are stronger to support this process. The result is lighter components & stronger than Strummer's ultralight cassette sprocket.
T700 & T800 Blend
Rims The Strummer Aeroflow Extreme carbon uses a mix of T700 & T800 for greater stiffness & strength. tall.
