Cotic have updated their SolarisMAX hardtail for 2020 with a steeper seat tube and no fewer than eight bottle bosses on the downtube! The new 29er hardtail mountain bike can be run with a 120 mm-140 mm fork, to your taste. This is meant to be a versatile do-it-all trail bike, built for enduro level races and fit as a bikepacking rig for month-long adventures. Here’s a wee intro to the 2020 SolarisMAX, a steel frame Cotic hardtail.

2020 SolarisMAX 29″ Hardtail

Cotic have been pushing their radical Longshot geometry since 2017, designing bikes around a short 35 mm stem for responsive handling, technical trail confidence and a roomy cockpit for long distance comfort. This year’s SolarisMAX is updated to better fit that bill, with a 0.5 degree steeper seat tube angle.

A 66° head angle is now paired with a 75° seat tube angle, consistent across the S-XL size range. Reach on the small frame would be considered very long by most standards at 439 mm. This stretches out to 461 mm in medium, 486 mm in large, and 513 mm in XL.


Seat tubes are relatively short – 425 mm in medium should give riders plenty of room to shift about in the cockpit when trails get janky. The chainstay measures 444 mm, the same for every size frame.

The 2020 SolarisMAX has widely spaced chainstays and seatstays that converge on a 148 mm rear end, allowing sufficient clearance for 2.6″ tires on 29″ wheels, or 3.0″ tires on 650b. This is Cotic’s signature 4130 cromo wishbone stay rear end featuring bridge-less MAX S-bend chainstays with Cotic Hexten gussets for improved fatigue life.

The front triangle is fabricated form large diameter, thin-wall, air hardening Reynolds 853 steel with a signature Ovalform top tube for a bit of vertical compliance. The seat tube is an exclusive Cotic-designed Reynolds 853 34.9 mm seat tube, said to give great precision to the ride.

The 2020 SolarisMAX uses a 44 mm standard head tube designed with external bottom cup for tapered steerer compatibility and zero stack top cup for minimal stack height. The bottom bracket is threaded and cable routing is external, keeping maintenance quick and simple.

Two sets of bottle bosses on the down tube are added for this model year for extra water carrying capacity. You can either run two bottles in a line, or use the lower set with a side-loading cage to get some extra water on board if you have a frame bag for a bigger trip.

I like the old head badge better. Bring back the Cotic Imp.

I imagine there are going to be a few comments about the eight water bottle bosses.

Hope there is a version without 8 bottlemount bolts on the downtube. While great for maybe 10% or less of peeps out there, it’s not what the majority of the people drawn to Cotic are about is my guess.

If companies would stop making bikes with shorter seattubes then sticking a bunch of bottle bosses on them in other places so they can put “bikepacking” in the description, that’d be great. When a small or medium bike can’t even hold a water bottle on the seattube, you won’t find an off-the-shelf frame bag to fit in there. It’s cool if you want to make a shreddy hardtail that can use a 170mm dropper, just don’t pretend like bosses all over it make it practical for carrying anything other than extra bolts.
