The Newmen ADVANCED A.50 is 15 g lighter (1,470 g vs 1,485 g claimed per pair); the Roval Alpinist SLX costs €50 less (€699 vs €749) at our October 2026 price check. The rim depth is 50 mm on the ADVANCED A.50 and 24 mm on the Alpinist SLX, the internal width is 23 mm on the ADVANCED A.50 and 20 mm on the Alpinist SLX and the listed tyre range is 23–63 mm on the ADVANCED A.50 and 24–38 mm on the Alpinist SLX.

General context for the specifications where these two differ. Numbers in superscript link to the sources below each topic. How much each point matters depends on your riding, tyres and bike.
Rim depth: aerodynamics, weight and crosswinds
Rim depth: 50 mm on the ADVANCED A.50, 24 mm on the Alpinist SLX.
Cross-sections drawn to scale from the catalogue values for outer width, internal width and depth; hooked rims show the bead hook. Simplified shape, not the manufacturer's exact profile.
Deeper rims generally reduce aerodynamic drag, which pays off most at higher speeds on flat or rolling roads, but they tend to weigh more and can be more affected by gusty crosswinds. In a BikeRadar comparison, 60 mm aero wheels were about a second per kilometre faster on the flat but slower on steep climbs than a considerably lighter set.1
How a wheel behaves in crosswinds depends on the rim shape as well as its depth,3 which is why TOUR measures steering torque in the wind tunnel, not just drag.2 Shallower rims are generally easier to handle in gusts, something lighter riders and riders on exposed roads tend to notice first.1
Internal rim width: 23 mm on the ADVANCED A.50, 20 mm on the Alpinist SLX.

A wider internal rim spreads the tyre beads further apart, so the same tyre mounts wider and with more air volume: roughly 0.4 mm of tyre width per extra millimetre of rim width.1 A tyre labelled 28 mm can measure around 30 mm on a 21 mm rim,2 so check frame clearance against the measured width, not the printed one.4
Typical road rims have moved from about 19 mm internal width around 2020 to 21–25 mm, together with wider tyres. A wider rim also raises the narrowest tyre you may fit and, on hookless rims, comes with pressure limits.3 Brands usually shape the rim around a target tyre width for aerodynamics, so the fastest combination is not simply the widest tyre.5
Newmen approves tyres from 23 mm to 63 mm for the ADVANCED A.50. Roval publishes no tyre range for the Alpinist SLX. The 24–38 mm in our catalogue is a Show My Bike assumption, not a manufacturer figure.

An approved tyre range is the span of tyre widths a manufacturer permits for a rim, based on the ETRTO/ISO tables for tyre and rim combinations.2 Not every brand publishes one: some give a recommendation only, or no maximum. The lower end is the narrowest tyre that fits that internal width safely; the upper end shows how far you can go towards wider, lower-pressure tyres for comfort and grip on rough roads or gravel, provided your frame has the clearance.4
In TOUR's tests, wider tyres at a pressure matched to their width roll about as easily as narrower ones on smooth surfaces and add comfort and grip on real roads, while a tyre much wider than the rim costs some aerodynamic drag.1 Pressure calculators such as Zipp's take the rim's internal width into account as well as the tyre.3
Spoke count front/rear: 21/21 on the ADVANCED A.50, 21/24 on the Alpinist SLX.

Fewer spokes save weight and can reduce drag slightly,1 but each spoke then carries more load and a broken spoke is more likely to leave the wheel unrideable.3 Wheels with low spoke counts usually state a maximum system weight;2 compare it with your own weight plus bike and luggage rather than judging by spoke count alone.
Warranty: 3 years on the ADVANCED A.50, a lifetime warranty on the Alpinist SLX; crash replacement is offered for both.

A warranty covers manufacturing defects; damage from a crash or impact is usually excluded.4 Crash replacement programmes cover that case, either free of charge or as a discount on a replacement. Hunt's H_Care is one example;2 Roval repairs or replaces crash damage free for two years on US purchases and at a discount of 20–35 % elsewhere, for up to five years.3 Some brands, Zipp among them, also include riding damage in their lifetime warranty.1
Terms differ widely: many programmes apply only to the original owner, need registration within a deadline and proof of purchase, may charge shipping or fees, and depend on the region you bought in.23 Check the current conditions on the manufacturer's page before relying on them.
How much lighter is the Newmen ADVANCED A.50 than the Roval Alpinist SLX?
15 g. The Newmen ADVANCED A.50 has a claimed pair weight of 1,470 g, the Roval Alpinist SLX 1,485 g. Both figures are manufacturer claims.
Which has the wider tyre range?
The Newmen ADVANCED A.50. Newmen approves tyres from 23 mm to 63 mm for the ADVANCED A.50. Roval publishes no tyre range for the Alpinist SLX. The 24–38 mm in our catalogue is a Show My Bike assumption, not a manufacturer figure. Check the manufacturer's guidance for your exact tyre and pressure.
What is the price difference between the Newmen ADVANCED A.50 and the Roval Alpinist SLX?
