SCHMOLKE Grenoble XS carbon fibre road bike frameset with fork – 52.5mm top tube, 1125g

BRAND NEW. NEVER BUILT. Retailed for 1800 euros. Bought but decided to go with a disc brake frame instead. My loss is your gain!

Comes with FRAME, FORK and HEADSET only. Listed weight for carbon fibre frame & fork combined is just 1125 grams! 🎈

Frame size is XS, aka 48cm. This makes effective top tube is 52.4cm. See Pic 6 for full geometry. Pics 3-5 are of the actual item.

If you're searching for Schmolke you know it is a weight weenie favourite brand. The Grenoble was their lightest frameset. I was going to pair it with some parts I'd accumulated – AX Lightness, Carbonsports Lightweight, Darimo, MCFK and Tune goodies – and it would easily have been a 5kg bike. I'd recommend at least Shimano Dura-Ace or Ultegra Di2, or SRAM AXS Red Etap. Or Campagnolo Super Record EPS 🤤

It takes BB30 or PF30 cranks, 27.2mm seatpost, 34.9mm front derailleur, and 100/135mm QR wheelset. Rim brakes only, not disc brakes.

Viewing at Bishan/Yio Chu Kang at my convenience.


Demands for every type of rider will definitely be met with this frame. Further cutting-edge technology is demonstrated by the tapered head tube (1 1/8″ to 1 1/4″). This results in a higher stiffness than common 1 1/8″ headsets.

The seat post clamp has been reduced to 27,2 mm in order to be able to mount a flexing seat post. Carbon seat posts with small diameters have evidently more flexing characteristics than any other seat posts. Thus a high amount of riding comfort is given despite the high stiffness of the frame.

In order to maximize riding comfort, 28 mm dimensioned tires can be mounted without difficulty.

The BB30 or Shimano Pressfit bottom bracket standard proves that the frame meets up with state of the art technology. This standard allows to assemble the bike with lightweight aluminum axes. Additionally the bulkier 30 mm shaft diameter makes the bottom bracket stiffer than common bottom bracket standards. As with the BB30 standard there is no need for bushings anymore, the weight of the bike can therefore be even further reduced.

Even small frame sizes are designed to fit two bottle cages.
Measurement for front derailleur clamp is 34.9 mm.
