PTO Verdict
“A big-arc carver for firm snow that starts turns easily and makes a lazy skier work to finish them.”
Best for: Advanced and expert carvers, club racers and former racers among them, who want GS-shaped arcs on hard, groomed snow and keep their weight forward.
Not for: Skiers whose day is mostly short, quick turns, or who head off-piste into soft snow: the G9 is a long-radius, 67 mm ski for firm piste. It is a hard teacher for anyone not yet carving cleanly, and Atomic's skill rating leaves Beginner blank.

Description
The Atomic Redster G9 Revoshock S + I 12 GW is a 67 mm, long-radius piste ski that Atomic sells together with its binding, as one system, for $1,385. On Atomic's three-level skill scale it is marked Advanced and Expert, its turn shape is listed as Long, and its 25/26 US product page gave the terrain as Race and Piste. Atomic's one-line description promises race technology aimed at precision and stability at speed.
Every length shares a 110.5 mm tip and a 67 mm waist, with tails of 96 to 97 mm, and each size adds a meter of radius: 15 m at 166 cm, 16 m at 171, 17 m at 176 and 18 m at 181. Atomic calls its profile Active Camber 0/100/0, and no rocker is named for it in either the datasheet or the catalog list. The edges leave the factory at 87° side and 0.8° base.
Atomic's catalog list names the build: Carbon Boost, Power Woodcore, Revoshock S, Structured Topsheet, TI Powered, World Cup Base Finish and an Ultrawall sidewall. The ski's 25/26 product page explains the parts: the core is ash and poplar, TI Powered means titanal, Revoshock damps ruts and grooves, Carbon Boost inserts add rebound at the turn exit, and a free-gliding plate underfoot lets the ski flex for grip along the whole edge. Only the 176 cm is weighed on the datasheet, at 3,291 g per ski, and nothing there says whether the binding is included.
Skiers who still skid turns, or who want a ski for soft snow off the piste, should shop elsewhere.
Ask us about length: we size you from height and weight and from the turns you like to make. Buy the G9 and its binding together at PTO, and mounting is free.

The take
“A big-arc carver for firm snow that starts turns easily and makes a lazy skier work to finish them.”
The longer the turn and the firmer the snow, the more this Redster gives back. A German magazine's 25/26 test found plenty of pull at speed and clean edge engagement, four of five Italian testers on the 25/26 ski listed stability or solidity among its strengths, and on a US retailer's 26/27 test page, a tester on Stowe hard pack summed it up as 'Wow! These fly!' Give it a groomer and room to let each turn run.
Getting the G9 into a turn is the easy part; finishing the turn is where it asks something of you. Turn entry came easily for 25/26 Italian testers and a 26/27 retailer tester, and the German magazine's 26/27 test called the ski smooth and willing to drift. The exit draws mixed reports. One 25/26 Italian tester found the release easy, while others on that team said leaving the turn takes a lot of energy and called the ski tiring and mentally demanding. On the retailer's 26/27 page, one tester felt the tail rebound noticeably when it was pressured too early, and another warned that a lazy or backseat skier gets outpaced and overpowered. We read those reports as one ski meeting different skiers: driven from a forward stance, it is the smooth GS ski the magazine describes, and skied from the back seat it wears you out.
Loose or soft snow takes the edge off the G9. A 26/27 retailer tester on loose granular found it hard to grab the hardpack and wanted more weight and damping at higher speeds. Even so, that tester recommended it for firm, hardpack conditions. A 25/26 Italian tester added that on snow that isn't compact, the 17 m radius takes good technique. The middle of the turn drew a remark in each season: slightly soft between a strong tip and tail for one 26/27 tester, a break in continuity for one 25/26 tester. Two remarks are too few to call that a flaw, so we'd treat it as a feel to expect.
If your day runs on short turns, this is the wrong Redster. The German magazine's 25/26 test also said short turns take strength and technique, and a 25/26 Italian tester listed short radius as a weak point. The 26/27 retailer page is split: one tester found the G9 most comfortable in long, clean arcs, and another, on the 171, called it quick-turning and snappy. The S9 is the Redster for that skier: Atomic lists its turns as Short, with radii of 11.3 to 13.1 m on lengths of 155 cm up to 170 cm, for the same $1,385 with the same I 12 GW. The X9S, at 14 to 15.6 m on 65 mm, bridges the two, and for groomers that soften through the day, the Q9 puts 75 mm underfoot against this ski's 67. Of those four systems, the G9 has the longest radii, 15 to 18 m, which makes it the Redster for skiers whose favorite turns are long ones.
Bindings we'd pair with it
Mount point: No mount-point figure appears on Atomic’s datasheet or in its catalog list; with ski and binding both bought from PTO, our technicians mount the I 12 GW free. Our pick: I 12 GW (Atomic), included with the ski.
- Atomic I 12 GWPart of the system; Atomic names it in the product title
Atomic's product name and catalog entry pair the G9 with this binding, and the system price includes it. Release values are a technician's job, worked out for each skier, so no number appears here.
No boot-sole norm for this system appears in Atomic's catalog list or on its datasheet, so a technician tries your boot soles in it.
Common Questions
- What changed on the Redster G9 for 26/27?
- Atomic's 25/26 US pages for this article, as they read on 11 October 2025, 3 January 2026 and 14 April 2026, show the lengths, dimensions, radii and weight Atomic gives for 26/27, so 25/26 tests describe the same ski. The price rises from $1,250 on those pages to $1,385, and Atomic's 26/27 catalog list also names an Icon Flex Interface, with no description, that those pages don't list. Atomic's pages for the older G9 + X 12 GW show a different build, with 68 mm underfoot, lengths from 167 to 182 cm, 16.6 to 19 m of radius and no Carbon Boost in the feature list, so tests of that ski don't apply here.
- Does the G9 come with bindings?
- Yes: Atomic sells the G9 and the I 12 GW as one system, priced at $1,385 for both. Boot soles vary, so a technician checks yours on the binding. Buy ski and binding at PTO and the mount is free.
- What length of G9 should I ski?
- From the 166 to the 181, the radius runs 15 to 18 m, one meter per step, so a shorter G9 makes a tighter arc and a longer one runs a bigger turn at speed. Sizing calls differed among the 26/27 testers for a US retailer: one found the 176 true to size, while another wanted more length for laid-out GS turns and would size up. We'll suggest a length from how tall and heavy you are and the arcs you like to make.
- Is the Redster G9 a race ski?
- Atomic's 26/27 catalog puts it in the Piste section, while its 25/26 product page tagged it for Race as well as Piste. A 25/26 test by a German magazine called it 'not a brutal race plank, but a sporty yet good-natured race carver.' That matches our view: a carver for the piste, shaped for GS turns.
