The character of this wheelset
A very light pair with clearly different front and rear rim dimensions, steel spokes and ceramic bearings. Compare its 49 mm front rim and 23.5 mm internal width with the alternatives below, then check your tyres and total system weight before making a buying decision.

Where the SES 4.5 Pro sits among the 127 road disc wheelsets in the Show My Bike catalogue. Each dot is one wheelset. Positions describe specifications; they are not a rating.
Weight
At 1,295 g, it is lighter than 91 of the 126 other wheelsets with a confirmed weight in our catalogue. Among the 58 deep-rim wheelsets with a confirmed weight, it is the 12th lightest.
Price
At €3,147, it is less expensive than 6 of the 126 other wheelsets in our catalogue. Among the 58 deep-rim wheelsets, it is the 4th most expensive.
Widest listed tyre
Its listed range goes up to 35 mm. Of the 126 other wheelsets, 85 list a wider maximum tyre and 14 a narrower one.
Rim-depth groups use the average of front and rear depth: shallow-rim below 35 mm, mid-depth 35 to below 50 mm, deep-rim 50 to below 65 mm, very deep-rim 65 mm and above. Weights are manufacturer claims; wheelsets with an unverified weight are left out of the weight comparison. Prices from our October 2026 price check.
03 / WHAT IT MEANS
What the specs mean.
General context for the SES 4.5 Pro's key specifications. Numbers in superscript link to the sources below each topic. How much each point matters depends on your riding, tyres and bike.
Internal rim width: how the tyre sits
The SES 4.5 Pro has an internal rim width of 23.5 mm and an external width of 30.8 mm.
internal23.5 mm
external30.8 mm
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
ENVE approves tyres from 28 mm for this rim and publishes no maximum. The 35 mm in our catalogue is a Show My Bike assumption, not a manufacturer figure.
SES 4.5 Pro28–35 mm
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
The SES 4.5 Pro uses 24 steel spokes front and rear.
SES 4.5 Pro 24 front / 24 rear · steel
A carbon spoke weighs roughly half as much as a premium steel bladed spoke,1 and brands state that carbon is stiffer for its weight.2 That is why carbon-spoke versions often use fewer spokes and weigh less: Hunt's Limitless Ti_UD uses 15/18 carbon spokes against 20/24 steel spokes on the standard Limitless.3 Some reviewers describe a more direct feel when sprinting; that is a riding impression, not a measurement.5
Steel spokes such as DT Swiss Aerolite or Sapim CX-Ray are standard parts that most workshops can source and replace.4 Carbon spokes are more sensitive to side impacts, for example from a derailleur or debris, and may need brand-specific parts or tools;1 some brands include spare spokes or crash replacement to offset this.5 Visually, the lower spoke count and slim blades give carbon-spoke wheels a lighter, more open look.
Ceramic hub bearings are a common premium option. CeramicSpeed quotes watt savings for upgrading hubs, bottom bracket and pulleys together.1 In independent Friction Facts tests of bottom brackets, the best steel and the best ceramic units were only hundredths of a watt apart, and seals and grease mattered more than the ball material.2
The lowest-friction setups tend to use lighter seals and grease, which protect less against rain and grit and need more frequent servicing.3 How long any bearing lasts depends mainly on seals, grease, hub design and maintenance.4
Start with the rim dimensions, then look at the evidence behind the complete wheel-and-tyre setup.
Rim geometry
The shape behind the profile
The SES 4.5 Pro has 49 / 55 mm front / rear, with an external front width of 30.8 mm. These dimensions describe its shape; they do not establish a measured speed advantage.
The front rim is 49 mm deep. For exposed roads, compare the front-wheel design and evidence for your tyre setup. Depth alone cannot predict how confident you will feel in gusts.
Rim depth in context
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
Some wheelsets use a different rim depth front and rear, and brands disagree on the direction. Roval's Rapide CLX II paired a shallower front with a deeper rear to favour stability.1 The newer Rapide III uses a slightly deeper front than rear, and Roval argues most of the aero benefit comes from the front wheel.2 Zipp's 454 NSW rim itself varies in depth along its circumference.3
Treat a split depth as a design choice of the brand rather than an advantage in itself. If crosswinds concern you, the front rim depth is the figure to look at.
Show My Bike publishes no aero or crosswind rating on product pages. Find My Fit uses rim depth and width as a rough proxy when it ranks wheelsets for your riding; how that works is explained on How We Score.
No automatic comfort or durability rating is assigned from rim width, spoke material, bearing type or warranty length.

Before you decide.
How much does the ENVE SES 4.5 Pro weigh?
ENVE claims 1,295 g for the pair, which makes it lighter than 91 of the 126 other wheelsets with a confirmed weight in our catalogue. Claimed weights do not always include rim tape and valves.
What tyre width fits the ENVE SES 4.5 Pro?
ENVE approves tyres from 28 mm for this rim and publishes no maximum. The 35 mm in our catalogue is a Show My Bike assumption, not a manufacturer figure. The internal rim width is 23.5 mm. On wide rims, tyres usually measure wider than the size printed on them, so check your frame clearance as well.
What is the internal rim width of the ENVE SES 4.5 Pro?
23.5 mm. The external width is 30.8 mm.
Is the ENVE SES 4.5 Pro hookless?
No. It uses a hooked rim, which also accepts tyres that are not approved for hookless rims, within the listed range and the pressure limits of rim and tyre.
How much does the ENVE SES 4.5 Pro cost?
€3,147 per pair at our October 2026 price check; the manufacturer's recommended price is €4,598. Prices change, so check the current offer with the retailer or manufacturer.
Why call the SES 4.5 Pro "Very light"?
Its 1,295 g claimed pair weight is below our 1,300 g boundary. The description concerns weight only. It is not a rating of stiffness, quality or suitability for a particular rider.
Are all the listed tyre widths equally aerodynamic?
A tyre range does not establish equal aerodynamic performance across that range. ENVE approves tyres from 28 mm for this rim and publishes no maximum. The 35 mm in our catalogue is a Show My Bike assumption, not a manufacturer figure. Check the tyre requirements for your own setup and the manufacturer's guidance on the best width for this rim.
