Tairin R1 Rear Hub
CHF342.65
This is the new Tairin hub, with the modular magnetically ratcheting R1 drive configuration. It features ring gears that are preloaded to ratchet with attracting and repelling magnets. The magnets are designed to attract the gears together so that their magnetism is strongest when engaged in torque transfer, and lowest during ratcheting to reduce freewheeling drag, which is the opposite of a spring system.With only one moving part, and magnets that don't fatigue in preload, it is almost service free.
The Tairin hub can be disassembled without tools, and the drive unit is removable with a tire lever.The Tairin hub can swap between the S1 and R1 drives without tools (the silent S1 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.

Key Features
- One long helix spring with short travel cycles ensures durability against spring fatigue and loss of ratcheting preload.
- Virtually no maintenance needed.
- Snap on end-caps allow tool-less removal of freehub.
- Sealed Cartridge Bearings, with a large standard bearing connecting the freehub to the hubshell that addresses any flex between both, making the drivetrain feel stiff and predictable.
- Self-contained and small drive modules removable with flat screw driver, allows the option to carry a spare drive kit (or an emergency face gear pair - available soon) for precaution in multi-day excursions or trips away from home.
- Swappable on the fly between Ratcheting (R1) and Silent (S1) modes on the same hub and freehub.
