Why it matters
Derived from Artech
R-series uses the same rim profiles as the Artech series but without Aeroscales and with steel instead of carbon spokes, at a lower price.

Wyjaśnienie specyfikacji
Total set weight1439 g (±5%)
Lower weight helps on climbs and repeated accelerations. For flat rides, commuting and carrying loads, comfort, durability and aerodynamics often matter more than a few grams. Frame, wheelset and complete-bike weights are not directly comparable.
Rim height45 mm front/rear
Deeper rims can help on fast, flat rides but react more to crosswinds. Shallower rims often suit lighter riders, climbing and variable winds. Mid-depth is an all-round compromise; depth alone does not determine speed.
Internal/external rim width28 mm / 38 mm, hookless
Internal width affects tyre shape and mounted width. More support can suit wider gravel tyres; a narrow road tyre does not automatically fit a wide rim. External width affects aerodynamics. Always check the approved tyre/rim pairing.
Tyre compatibility35-65 mm, hookless tubeless only, optimum 40 mm
A supple, lightly treaded tyre suits fast tarmac miles; loose terrain needs more grip and volume. Tubeless or hookless labels are compatibility requirements, not styling choices. Width, model, pressure and frame clearance must all agree.
Max tyre pressure4.0 bar / 58 psi
This is a limit, not a recommended riding pressure. Suitable lower pressure can improve comfort and grip on rough surfaces. Correct pressure depends on total weight, tyre width and terrain. Hookless systems have specific tyre and rim limits; never exceed either.
Spokes21F/24R Sapim CX-Ray
Spoke material, count and construction affect stiffness, weight and servicing. Low weight may matter in racing; rough routes and everyday use also demand durability and repairability. Spoke count alone is not a quality measure.

Check axle dimensions, rotor mounting and cassette driver on your bike. The approved tyre-rim combination and frame clearance must also match. A matching brand name alone is not enough.
