All About Zwift’s New Felt IA 2.0 and Scott Plasma RC Ultimate TT Frames

May 16, 2022

LAST UPDATED May 13, 2022

Zwift’s May update included the two new “triathlon-specific” TT frames: the Felt IA 2.0 and the Scott Plasma RC Ultimate. Both are upgrades to existing frames in game (the Felt IA and Scott Plasma), and both are rated at 4 stars for aero performance, 1 star for weight – just like every other TT frame in Zwift.

Normally we do separate posts for each new frame and wheelset, but it turns out these frames perform identically, are priced identically, and are level-locked almost identically… the Felt is available to level 34+ Zwifters, while the Scott is available at level 33+.

Here’s how each is described in the Drop Shop:

Felt IA 2.0: The IA 2.0 is the latest incarnation of Felt’s venerable IA platform. Entirely redesigned, the exciting new silhouette, smart integrations, and massively adjustable riding position is purpose-built for triathlon. If solo speed is your thing, you’ve got to try the IA 2.0.

Scott Plasma RC Ultimate: With the Plasma RC Ultimate, Scott really decided to flex their “Aero Muscles”. This triathlon-specific bicycle features fully integrated cables, a hydration system, and storage boxes. They’ve also made it versatile, making sure that anyone can find their most efficient cockpit position on the bike. If you thought the last Plasma was the fastest in the world (it was) then you ain’t seen nothing yet.

We ran both frames through our normal testing procedure in order to discover exactly how they stack up against other frames in the Zwift universe.

Here’s everything you need to know about the performance of the new Felt IA 2.0 and Scott Plasma RC Ultimate frames in Zwift.

Aero (Flat/Rolling) Performance

Both the Felt IA 2.0 and Scott Plasma RC Ultimate turn in very fast flat times. In fact, they’re tied for 2nd place in the universe of TT frames on Zwift, only slower on the flats than the Canyon Speedmax CF SLX Disc.

Both frames are faster than their older versions in Zwift, but while the Felt IA 2.0 trims just 1 second off the Felt IA, the Scott Plasma RC Ultimate trims 15 seconds off the older Scott Plasma.

The Felt and Scott both turned in a test time of 49:43. By comparison, the Canyon Speedmax CF SLX Disc is 2 seconds faster, while the slowest name-brand TT frame (Pinarello Bolide TT) is 16 seconds slower on our test course, which is two laps of Tempus Fugit totaling 34.6km.

Climb Performance

The Felt and Scott both turned in a matching Alpe du Zwift test times, and those times were faster than any other TT frame in the game.

Both frames are faster than their older versions in Zwift, but while Scott Plasma RC Ultimate trims just 2 seconds off the older Scott Plasma, the Felt IA 2.0 trims 8.5 seconds off the Felt IA.

Their Alpe time was 50:01, which is 41 seconds faster than the slowest TT frame in Zwift (Trek Speed Concept SLR 9) and 1 second faster than the previous best climber, the Specialized Shiv S-Works.

Note: all test results above are from a 75kg, 183cm rider holding 300W steady using Zwift’s stock 32mm carbon wheelset.

Conclusions

On a pan-flat TT course like Tempus Fugit, the zippy Canyon Speedmax CF SLX disc is still the best frame. But if the course includes hills, you’ll want to be riding the Felt IA 2.0 or Scott Plasma RC Ultimate. That’s because they outclimb the Canyon (and every other TT frame in game), and are only 2 seconds slower than the most aero frame over a 50-minute flat test!

So which of these new frames do you pick? Whichever one looks the best to you! Be warned, though – as has been the case with other frames lately, the color slider shows up but doesn’t actually work. So what you see is what you get:

The Felt IA 2.0 and Scott Plasma RC Ultimate are now listed on our Master Zwift Frames List. We’ll also be adding them to the following posts:
