Colnago G5-X Wheels: Keep Zipp 303 XPLR and Vision TC45 i30 Apart
Colnago G5-X wheels are not described by one universal carbon-rim specification. The inspected Red build names Zipp 303 XPLR SW, while Force and Rival name Vision TC45 Carbon i30. Their rim heights, internal widths and construction descriptions differ, even though all three complete-bike builds share the listed 40T and 10–46T gearing.
Colnago G5-X wheels: compare the two packages
The Red table describes its Zipp rims as carbon hookless, with Tubeless Straight Side wording. It gives a 54 mm rim height and 32 mm internal channel width. Keep the two numbers attached to their labels: height and internal width are not interchangeable measurements.
Force and Rival instead list the Vision package as carbon clincher and tubeless-ready, with 45 mm rim height and 30 mm internal channel width. The i30 model name matters. An older or regionally different TC45 description should not be merged with this identified US table merely because part of the name matches.
Carry the tyre entry with its wheel entry
The Red block names Goodyear XPLR Inter TLR 700x50 tyres. The Vision-equipped blocks name Pirelli Cinturato Gravel RH 700x50 TLR. That shared nominal size does not make the wheel constructions identical, and it is not a general approval for moving any tyre between the rims.
This guide identifies the manufacturer-listed packages. It does not supply a tyre-pressure limit, hookless compatibility list or conversion procedure. Those require the applicable wheel and tyre makers' guidance for the exact products, rather than a size string taken from another assembly.
Keep the complete build visible in the comparison
The Colnago G5-X Bike — Carbon Blue listing identifies its colour as Carbon Blue. Its local build listing pairs a groupset label with the wheel name. Confirm both when comparing bicycles; a photograph of a Colnago gravel frame is not a substitute for that complete equipment description.
The older G3-X in the photograph shows a different dated wheel arrangement. Its visible rims supply gravel-family context, without an exact wheel model or measured depth being established here. Read the brand guide alongside the Colnago topic for the wider distinction between platforms and builds.
