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.
Weight: what the grams mean
The Élan Ultra 6 Laser-Etch Grey is 168 g lighter per pair (1,289 g vs 1,457 g, manufacturer claims).
SES 6.71,457 g
Élan Ultra 6 Laser-Etch Grey1,289 g
On a steady climb only total weight counts: a gram in the wheels costs the same as a gram in the frame or a bottle.1 A common rule of thumb is about 2 seconds per 100 metres of climbing for every kilogram, so 150 g works out at roughly 3 seconds on a 1,000 m climb.2
Rim weight matters somewhat more when you accelerate, because the rim spins as well as moves forward; physically that effect is at most about twice that of frame weight, and only while speeding up.1 Claimed weights are measured differently from brand to brand: some include rim tape and valves, others do not, and tolerances of around ±30 g are common.3 Independent weighing usually lands close to the claim once tape and valves are accounted for.4
Rim depth: 60 mm front / 67 mm rear on the SES 6.7, 65 mm on the Élan Ultra 6 Laser-Etch Grey.
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
The SES 6.7 (60 mm front / 67 mm rear) uses different rim depths front and rear.
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.
Internal rim width: 23 mm on the SES 6.7, 24 mm on the Élan Ultra 6 Laser-Etch Grey.

Élan Ultra 6 Laser-Etch Grey · internal24 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 25 mm for the SES 6.7 and publishes no maximum. The 32 mm in our catalogue is a Show My Bike assumption, not a manufacturer figure. Scribe recommends tyres from 28 mm to 35 mm for the Élan Ultra 6 Laser-Etch Grey. This is a recommendation, not an approved limit.
SES 6.725–32 mm
Élan Ultra 6 Laser-Etch Grey28–35 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 6.7 uses a hookless rim, the Élan Ultra 6 Laser-Etch Grey a hooked rim.
SES 6.7 Hookless: straight wallsÉlan Ultra 6 Laser-Etch Grey Hooked: lip grips the bead
Simplified sidewall cross-sections.
A hooked rim has a small lip on each sidewall that grips the tyre bead; a hookless rim has straight inner walls.1 Under the ETRTO/ISO standards, road tyres on hookless rims must not be inflated above 5 bar (72.5 psi),2 there are minimum tyre widths for each rim width, for example 29 mm on a 25 mm internal rim,5 and most wheel makers publish lists of approved tyres.3
Manufacturers cite precision, strength and lower weight for hookless rims; independent coverage describes the weight saving as modest. Hooked rims accept a wider choice of tyres and higher pressures.4 Both work within the standards: check the rim maker's tyre list and the pressure you like to ride before choosing tyres.
The SES 6.7 uses steel spokes, the Élan Ultra 6 Laser-Etch Grey carbon spokes (24/24 vs 20/20 front/rear).
SES 6.7 24 front / 24 rear · steelÉlan Ultra 6 Laser-Etch Grey 20 front / 20 rear · carbon
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.
The Élan Ultra 6 Laser-Etch Grey uses ceramic hub bearings, the SES 6.7 steel bearings.
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
Warranty: a lifetime warranty on the SES 6.7, 3 years on the Élan Ultra 6 Laser-Etch Grey; crash replacement is offered for both.
SES 6.7Lifetime · crash replacement yes
Élan Ultra 6 Laser-Etch Grey3 years · crash replacement yes
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.
