Description

Uncompromising Aerodynamics & Featherweight Performance

The Serenade ARWS R2 Carbon Spoke Wheelset represents the pinnacle of modern carbon wheel engineering. Built with our ARWS ultra-light carbon rims, 4.0mm T-head carbon spokes, and the ultra-reliable Titanium 45T Star Ratchet R2 hub system, this wheelset delivers lightning-fast acceleration, unmatched lateral stiffness, and superior aerodynamic stability.

Specifications & Weight Breakdown

All wheelset weights are calculated using our precise build standard:

Serenade ARWS R2 carbon spoke road bicycle wheelset 50mm depth UD matte

Wheelset Weight = (2 × Rim Weight) + Hub Weight (230g) + Carbon Spokes Weight (40pcs × 3.4g = 136g)

Engineering Features

1. Modern 25mm Wide-Bed Aerodynamics

Featuring a 25mm inner width and up to 32.4mm outer width, the ARWS rim design perfectly supports modern wider tubeless and clincher tires (28c to 35c). This wide profile reduces tire bulging, smooths airflow over the rim transition, and allows you to run lower tire pressures for increased traction and lower rolling resistance.

2. High-Modulus 4.0mm T-Head Carbon Spokes

Weighing only 3.4g per spoke, our 4.0mm T-head carbon spokes save significant rotational weight while boosting lateral stiffness by up to 30% compared to traditional steel spokes. Engineered for precise wheel builds, these spokes support custom lacing alignments up to 5mm max width.

3. Serenade R2 Titanium Hub Architecture (230g/pair)

The R2 straight-pull hub is precision-crafted for long-term power delivery:

  • Titanium 45T Star Ratchet & Freehub: Prevents cassette teeth bite marks and ensures instant 8-degree pedal engagement.

  • Premium Bearing Layout: Front hub houses 2x 6803 2RS bearings; Rear hub houses 1x 6803 + 1x 17287 bearings; Freehub houses 2x 6803 2RS bearings.

Frequently Asked Questions

Q: Why is Titanium used for the 45T Star Ratchet and Freehub?

A: Titanium provides superior hardness compared to standard aluminum. It completely prevents modern high-torque cassettes from biting into the splines while extending ratchet tooth lifespan under heavy loads.

Q: What freehub options are available?

A: You can choose between Shimano HG and SRAM XDR titanium freehubs during checkout.

Q: What tire size is ideal for the 25mm internal width?

A: We recommend 700x28c to 700x32c tires for optimal aerodynamic efficiency on paved roads, and up to 700x45c for gravel setups.
