Tetsuo Masamune mono aerobar feedback

Does anyone own these and provide any feedback?

Mine arrives tomorrow (!), so I’ll keep you posted; for a Scott Plasma 6 RC Pro that’s also en route so I won’t know for a while.

Wow! Good for you!!!

Looks really nicely made, but only one size it appears? I also wonder why they didn’t make the backside of the them more of a smooth fairing. I’m sure they tested them, so I’d assume fast if you are in the right position. I really like the layout, and that they have 3d files available. Seems like an invitation for China to copy them though, but hopefully not. :frowning:

Additional Information - Two sizes, with dimensions here

Looks to be a bit short, but not too bad, for me at least.

Will post this here. Here’s a quick video of someone I put on this bar. They were on scoops with an extender kit and their mechanic deemed that unsafe, which I agree with. Connor Reynolds on Instagram: "Is all that you see is a guy on a bike? New saddle and new aero bars for comfort and aerodynamics. 56/42 chainrings for descent control and speed. And OSPW for fun. And the new paint job to replace the scars from getting run off the road and crashing. All of these pieces meticulously selected to make it the best for me. But I also see thousands of hours, tears, pain, ups, downs, love, determination, care. So much has gone this. All of these pieces both physical and mental have culminated into this. Truly so much exists in the video. And so much exists in all sport especially as you keep hammering. #thegrind #hawaii #ironman #love #bikesarelife"

You can also head over to Matt McElroyā€˜s Instagram page. Is he plenty of videos of him on these bars?

Thanks very much! Out of the box, the build quality is very impressive!

The underside is definitely not smooth, but, it looks cool. And looking fast is half the battle.

Of course it’s a rigid cockpit and not customized (perhaps the Tri-C custom would be the route to go for this level spec), but with my being 6’2ā€ it is still just wide enough that I’m confident I should be able to comfortably hold an aero position for an IM, especially after a dynamic bike fit.

Did you get the mono or double handle? Wondering if the mono handle is twitchy?

Congrats and post a picture of your bike when you get it built!

Are they not only doing the mono now?

I believe there is an option for the hand grip to be front to back mono or side by side double grip.

I just got mine the other day for the Gen 3 Speed Concept. I have not had the time to install it yet, but should be able to in the next day or two. I got the mono and double grip as I wasn’t sure how the mono would feel.

Thanks! Really appreciate it.

You had the option to order both and I ordered both just in case; I’m thinking about having the mono installed with the initial installation and if I find that it’s not stable I’ll switch to the dual handle. I ride MTB also and have felt pretty stable in the aerobars so thought I’d start out with mono to double down on the narrower front.

Will do! Scott Plasma 6 RC pro with the Tetsuo cockpit, AeroCoarch Zephyr front wheel and Orbit disk rear, with the Vision Metron carbon crankset. Really excited. Have been a triathlete for 23 seasons and this is my second tri bike (current and first one is a 2010 Felt B12 that’s served me very well).

bumping this. Anybody do any aero testing with these?

Soooooo, any feedback? It certainly looks cool.

To me, it looks like it adds more surface area and could act as an air dam. I tested a DYI version of this and it was slower. I’m guessing that if its at the right angle and the right shape, there could be an advantage to it but like many things, its likely personal to your setup and position.

I have it for my Trek SC gen 3 and absolutely love them. highly recommend them. Light, strong, functional. very easy to install. I went the Mono and love the feel when riding outside.

I agree, I also have it for Trek SC gen 3 with the monogrip. The adaptor plate fit perfect and was very easy to install. Obviously this will not fit everyone since there no adjustment with the width but it fit me perfectly. I can stay in aero all day with it. The BTA solution and computer mount blend everything together. I have no aero testing to say if its faster or slower but it definitely allows me to stay in aero more comfortably much longer than other setups I’ve tried which is a win for me. Have no concerns with the safety of it, feels very strong and stable. Also the owner Marcos is great, had a few questions and he was very responsive and helpful.

Well, I noticed there’s a fundamental understanding with many monobar designs that seems to be lacking, which could negatively affect performance versus separate bars. Although there are exceptions, most monobars are simply a bridge between extensions, not a purpose-built streamlining device despite what the aesthetics might suggest. This is why they tend to test either marginally better or sometimes worse.

I spent over a decade building my own front fairings for personal use. First, it was a project to block the wind from my upper body in the fall. I’m in Canada, and here the cold weather could hit us as early as October. Riding at speed causes the wind chill factor to drop below freezing on some days. I wanted to extend my riding season before the snow fell and this was the best way I could achieve it without wearing multiple layers of restrictive clothing.

To make a very long story short, the final version of the fairing turned out to be effective at increasing my average speed, which was unexpected because I am not that fast a rider compared to many in this forum. Several kph faster average speed over what I was doing on that bike (vintage ā€˜80s steel road bike) felt like a revelation.

Granted, what I came up with was far larger than these monobar systems but the general design considerations still apply. Simply joining the aerobars with a flat shape to bridge them is a crap shoot. If the bars are really close together it might help. If not, then it could behave as an air dam. The monobar needs to be shaped with special consideration to the direction of air flow, which doesn’t seem to be the case with some of the commercial systems I’m seeing. The entire cockpit may even need to be redesigned around the monobar to be truly effective. In other words, lots of time in the wind tunnel.

Thanks! Sorry haven’t logged in for a while.

I love it! It’s incredibly comfortable and stable. The bottle holder with a Xlab Gorilla cage works great. The Garmin mount holds the computer at just the right spot. It feels compact but incredibly comfortable, somehow like it was custom made for me.

I wouldn’t ever look for a different cockpit. highly recommend!

That said observations of the bottom being not very smooth (like the new Canyon release cockpit is) are right on and I doubt it’s faster than my prior PD aero extensions but I don’t really care. It will be fast enough and by fitness I could hit my race goals regardless.

Love the fit and quality of it. Very pleased.

Cheers!

FWIW though I also changed bikes I don’t think mine is any faster than my prior set up (Vuka aero base with PD aero extensions),

but,

it’s incredibly comfortable, light, feels stable and I think looks really cool so I’m quite happy with it.

The more I think about it, ideally you would have something on top of each forearm that made each one the shape of an airfoil with a narrow trailing edge relative to a round leading edge (forearm). But you need to support yourself so that would not work. It seems like two extensions that keep the relative parabolic shape of each forearm relative to the wind should be better …and to your point about riding in the cold in Canada (spring or fall), riding aero was always warmer than sitting up, but riding with an air dam in front of the arms would make it warmer (but should be slower)
