*MAVIC* ksyrium heritage  wheel set a shiny set of wheels from Mavic has arrived.


Ron-san from Ultradynamico is looking very attractive in these photos, but I would like to check the wheels on his bike.

If you are into old Mavic stuff,  you’ll soon notice that the hub has their OG logo. This logo was used from 1923 to 1945.

These wheel sets were planned to be a Japan exclusive project, but they apparently got so many demands from around the world, making them shift to a global release.

There are rim brake models and disc brake models for these wheel sets. The disc brake wheel sets are QR convertible with the separately sold adapter to use for bikes like the OG Surly Stragglers.


Mavic is a historic brand that pioneered the shift in bicycle wheel materials from wood and iron to aluminum.

They developed their first aluminum rim in 1934.

Compared to the weight of rims at the time (1200g), the new Mavic aluminum rims were overwhelmingly light (700g), which lead them to the overall victory in the Tour de France.

The Ksyrium series, introduced in the late 1990s, established the concept of high-performance factory-built wheels a rarity at a time when hand-built wheels were the norm and became a masterpiece beloved by both professional and amateur cyclists.

The wavy shape of the rim is distinctive, but it also serves a purpose.
The section pulled by the spokes is thickened for durability, while the areas between spokes have reduced rim thickness for weight reduction.

A big difference compared to hand-built wheels is that the rim has threads cut into it, so there’s no drilling for the nipples, meaning you can go tubeless without a rim tape.



Accessories for both models include a tubeless valve, a decal set featuring numerous Mavic logos, and a dedicated nipple wrench. Of course, the rim brake model also comes with QR skewers.

A reissue of the all-polished finish, symbolic of premium wheels during the heyday of steel frames in the 1970s and 80s. As a new-tech guy myself, I thought “an aluminum rim in this day and age?” but I become more interested in the wheel sets after doing some research. I’m pretty amazed that they even made both rim brake and disc brake models.


Love these levers on RON’S BIKE CR1 Country Road.

Long ago, Mavic developed everything from hubs and pedals to headsets, cranks, and rims under the “All MAVIC” concept.
To elaborate further, they even developed the first electric derailleur back in 1992.





Ride with ULTRADYNAMICO in Portland 2025

The CR1 was featured in The Radavist, which he had these wheels on. I wonder if he’s a fan of Mavic from being an ex-road racer.

Building wheels with hubs from Phil Wood, Chris King, and White Industries can often be tough on the budget, but since these are complete wheelsets, they seem reasonably priced. They don’t have that cheap look common with complete wheelsets and are  genuinely good wheels.

I want them!

The Mavi Ksyrium SL Heritage wheelsets are now available in stores and online.
