Mcfk already had two depths of carbon road rims in their catalog, but now it’s time for two more. Wanting to provide consumers the ability to mix and match front and rear depths, the new rims slot in nicely with the original 35 and 55mm versions.

Stating that their rims are 100% made in Germany, these particular rims are meant for road and cyclocross use – but they are disc brake only.

All of the rims measure 26.5mm wide externally, and 18mm wide internally and are tubeless ready with a hooked bead profile.

It sounds like the valve seat is sunk into the rim channel which makes the installation of tires easier.

Inside the rim, you’ll find laminated spoke holes which are formed rather than drilled, and preformed ball head nipple seats made to fit Sapim and DT Swiss nipples for the perfect build.

For the 45mm rims, wheelset weights start at 1330g and prices at 1,788.90 €.

The 25mm deep rims use the same internal and external width as well as construction.

The biggest difference is the height which appears to save about 25g per rim with complete wheels starting at 1250g. Complete wheelsets still sell for 1,788.90 €.

Molded spoke holes with external nipples. That “other” brand said it couldn’t be done. I’m Envious.

Is that the first asymmetric carbon rim?

Not at all. Kappius, Nextie, Duke and others have offered offset spoke holes for several years.

Dose this company get its name from the film Withnail and I?

Wow, 1.3kg for a 45mm deep profile wheels, that’s quite light! Though I do wonder how does an assymetrical disc profile compares to the more common U profile.

And most manufacturers is able to achieve 1.4kg 50mm deep with a hookless bead profile, so I’m surprised to see a hooked bead profile achieving even lighter weight!

The whole hooked/hookless thing needs to be finalized. Wheel to tire connection is critical to rider safety and you literally have two systems in play here with various parties saying its safe or unsafe.
ETRTO needs to kick in gear and provide some clear definition. Right now that group should be embarrassed.

Roval CLX 50 are 1,415g but are 5mm higher and 3mm wider external and internal – I would prefer these unless I do time trials. 18mm on the inside are for 22/23mm tires.

In the 70-80’s someone probably said the same about aluminum.
More options means prices go lower. If for nothing else cfrp’s properties suit it well for forks and rims

I don’t get it. More aero disc wheels that are too narrow for 25mm tyres. A 25mm tyre on this wheel will be wider than the 26.5mm width of this rim, and mess up the aero benefit of the wide wheels. Mcfk, what tyres do you recommend riders use on these rims for an aero gain, 23mm?

Almost all disc bikes since 2015 came standard with 25mm tyres, Several years of disc brakes in the market mush make for enough riders ready to upgrade their bikes with some wheels wide enough for 25mm tyres by now. I’d love a set of ENVE 4.5 AR’s, but I’m waiting for something more affordable.

A lot of 2018 models are now coming standard with 28mm tyres, and allot of people on older model disc bikes are moving to 28mm tyres. I don’t see many wheel upgrade options yet.

This whole super-wide rim trend is a little over-rated. There might be a measurable difference in the wind tunnel, but real-world gains are marginal. Valverde just became World Champion on outdated Campagnole Boras.

Anyway, the MCFK’s are stunning wheels, with a reasonable price tag (at least compared to ENVE or Zipp).
