**the S1 returns for the 2024 season!**
This is the new Tairin hub, with the modular silent S1 drive configuration. Featuring face gears that dissengage when freewheeling for a complete silent ride.
The S1 features our Floating Engagement Index, designed to ease the effects of pedal kickback from some frame suspension designs. The floating engagement allows the S1 freehub to be 15 degrees from engagement every time the freehub is driven forwards after freewheeling, as opposed to ratcheting hubs, where the angular distance from engagement is up to chance within the range of the degrees of engagement.
The Tairin hub can swap between the S1 and R1 drives without tools (the magnetically ratcheting R1 drive kit is not included and can be purchased separately).
Convertible between most axle standards, we have 4 platform models:
-Standard: that can be converted between: 12x142mm, 10x135mm, 12x135mm (on request) and boosted with a kit to 12x148mm
-Boost: (native at 12x148mm) that can run 10x141QR and can be Superboosted to 12x157mm with our unique SB kit here
-Super Boost: (natie at 12x157mm) which can convert to 10x150mm, 12x150mm (on request)
-Single Speed Specfic: 10x135mm, 12x142mm, 12x135mm (on request) which features a short freehub for chainline adjustment and a non-dished symmetrical & centered wheel build.
Designed with high torque capability and easy tool-less drive system replacement as the top priority, the Tairin hub's S1 and R1 drive modes both feature ring gears that apply all their teeth disposed around the ring during torque transmission. The full meshing of teeth around the rings allows maximum surface contact, for the highest torque transfer-to-mechanism weight ratio. The drive rings of the S1 and R1 systems are easily removable and replaceable, so the hub's lastingness is unaffected by wear and tear of the clutch drive. We based the ring gear of the S1 and R1 on the popular and public star-ratchet, so the hub is compatible with those existing star-ratchets.
This hub has no torque/weight rating. And suits all bicycle disciplines.
Disclaimer: because of the nature of the silent hub S1 having the ring gears dissengaged and fully apart when freewheeling, sometimes when re-engaging at standstill/crawling speeds, there can be one audible click due to the teeth of the rings meeting tip to tip (and jumping to the next tooth set). This is per design and only happens once in a while. It doesn't happen when re-engaging at normal/fast speeds, or when fully engaged.
