If you will be using Di2, The position of the junction box is key when the bike is put together. To me the 2 most convenient places are inside the bento box, or hiding under the seat.
Recently the piece that holds the rear derailleur to the frame broke, that piece has to be ordered from Scott, and it takes time.
As others mentioned get the right size it runs big, I am 5-7 and the Small barely fits me.
I'm 5'8" / 155lbs and are riding a 51 in the Felt IA1 with 55mm stack.
The deal I'm looking at is for a 51 plasma, so I dont have much choice. So wondering if the geometry might work
I really love my Plasma. The front hydration is the best integrated solution I've ever seen/used. It's easy to put on, easy to take off, easy to clean, easy to fill while riding in aero, and it's held solid in place, no rattles. The bento is a good size â€“ plenty big for all my calories in a 70.3 though not big enough for everything I'd need in a a full. Not sure any single bento would be big enough for a full though. The brakes are surprisingly easy to work on for being so hidden. I imagine the build is difficult (my Di2 junction box is under the seat) so you'll want to have a good mechanic build it for you.
I did change a few things out over the first season I had it:
â€˘ I did not like the stock Profile T5. They were too short and too shallow. I needed something longer and wanted something that would give me a higher hand position. After trying Zipp Evo70, Evo110, and some Redshift ski bends I went with the Redshift and I love them.
â€˘ I initially thought the stock F35 pads were fine, but they don't have many position options and I've always preferred pads with more curve to them. When Profile started selling their Ergo armrests
I ordered a pair and I absolutely love them. I feel more solid/stable riding aero and the Ergo armrests have many more position options so you can fine tune your reach and how narrow (or wide) your arms are much better.
â€˘ I was running a Stages power meter so I swapped the Ultegra rear brake for a TriRig Omega X. It was super easy to swap and works great. I've since switched to a P2M NGeco so I could go back to the Ultegra but I've stayed with the Omega X.
Potential downsides to the Plasma:
â€˘ Even with the Ergo armrests the front end doesn't have as much reach adjustment as some other bikes. You can find ways to give yourself more reach if you need it â€“ the Ergo's help, and you can swap the left/right brackets â€“ but with only one stem option that allows you to use the front hydration you're still going to be more limited than on a bike with more stem options.
â€˘ You can't tilt the extensions. Technically Drag2Zero has a work around
, but it's overpriced (like their storage box) and I think requires you to also purchase their armrests. A tilt kit from Profile Design would be awesome.
â€˘ I wish it had a draft box for a spare kit like the Speed Concept, QR, BMC, Premier, etc. have. I usually use an X-lab aeropouch but a dedicated draft box would be nice.
â€˘ It's a reasonably tall bike so check your fit with their prescriber
. I'm 6'2" with long legs and a short torso and the size large is great for me (pad x/y 510 and 670) but you'll want to be sure of your fit.
