Cotic has added a special edition titanium frame, to its gravel bike range.

Best known for its steel mountain bikes, with their progressive geometry, Cotic also markets the Escapade gravel grinder. And that frameset has now been built in gloriously resplendent titanium, creating the Tonic.

The 3Al/2.5V titanium tubes not only look fantastic, but they make Tonic 600g lighter than Escapade. Geometry numbers are unchanged, which means the Tonic sits at a 72-degree head angle, supported by a 73-degree seat angle and 397mm of reach, on a size large.

All Tonic frame sizes use the same 425mm chainstay length, but the bikes have slightly different rear ends, compared to Escapade. Clearance rates at 700x44C, which should accommodate those large casing gravel tires.

At the front Cotic has opted for an RB5 carbon fork, with very generous tire clearance numbers, a 12x100mm axle and 45mm offset.

Riders can roll either a 700x45c or 650x1.95in front tire without issue and at only 550g, the Tonic’s fork should be very easy to lift over trail features and get that gravel bike bunny hop going.

Some of the notable design features on Tonic, include the fork cage mounts and diverse cable management options, including semi-internal routing and dropper seat post compatibility.

Cotic is offering a range of build options and even its own custom frame bags, for those Tonic owners who wish to use their shiny steeds for some gravel adventure riding.

You will be incredibly lucky to see one in real life, though. Cotic is only building 32 Tonics, for the 2021 production run.
