Product Description


The Pinarello Gan GR Disk and GR-S Disk are nearly identical. The main difference is that the GR (think GRavel) does not have a shock atop the seatstays. This makes the bike simpler and lighter, if a bit less forgiving when riding over really rough roads.

The GR and GR-S both came from the same place: a bike modeled on the Dogma K8 platform but adapted for normal hard-charging bike riders who want a fast, confident gravel-grinding rig. GR doesn’t mean that’s where you do all your riding, but you want something that can handle the roughest roads imaginable. The GR will be as fast there as any, and then, when on smooth pavement, faster than its brethren.

You might be wondering what is the difference between this and the Gan K, which also seems to be following a similar line. They are fairly similar, though this has a bit less bottom bracket drop, longer chainstays, a bit more fork rake, and more stack. In other words, more room for fat tires as well as a taller head tube for those who want a slightly more upright position.

How fat?  Try 35mm. That’s wider than many touring tires. It’s wider than what’s permissible in UCI-sanctioned cyclocross racing. It’s a size that means a wide footprint and low pressure for both great grip and incredible comfort.

This is something special, a mixed-surface bike that still is designed to go fast. It’s not just the geometry that is racy, but the tube shaping. As with the K8, these tubes benefit from Pinarello’s FlatBack profile down and seat tubes. The design is aero, but comfortable, as the leading edge airfoil is chopped down in back, both to improve comfort and minimize weight. The heat tube, fork legs, and seatstays are also shaped for aerodynamics, but a bit less so to helps the Onda shape with vertical compliance. The seat post and stem are aero a well.

As the name indicates the bike is set up with disc brakes. The brake mounts are designed for rotors up to 160mm in diameter. The fork has a flat-mount system for the front caliper. The rear triangle has Pinarello’s RAD System for mounting the rear brake caliper. It’s a lightweight, secure means to fix the caliper to the stays without bulking the chainstay. By keeping the seat stay thinner, the ride is closer to that of a bike with conventional rim brakes. Keeping the lateral rigidity high as well as keeping things secure and simple are thru-axles, both front and rear. 12x100mm in front and 12x142mm in back. More secure mounting, potentially faster wheel changes.

This Gan also boasts many of the cool design extras of the K8. Tapered 1 1/8” to 1 1/2” steerer. Think2 internal cable routing-which works with mechanical, electronic, or hydraulic systems. If you go the electronic route, the battery goes in the seatpost, though you’ll need an accessory adapter if your bike doesn’t come with electronic shifting. The bottom bracket is the reliable Italian threaded standard-easy for servicing.

The Gan GR Disk is easy: one bike for a complicated relationship with roads.
