Notice on the new Dimond


https://51-speedshop.com/...er-aero-bar-system-1



Bar Features
  • Nearly invisible to the wind, due to the proven Kamm-Tail airfoil design, and unyielding to even the strongest sprint induced torque.
  • Radial shaping of the pursuit bar, combined with a 5 degree up tilt gives the rider greater control over the bike.
  • Unique "mono-riser" mounting system allows height adjustment, angulation and stack adjustment through a simple 2 bolt design.
  • Three unique extension shapes based on rider preference.
  • Carbon reinforced nylon pad holder provides rigidity and support.
  • Proprietary arm pad provides the ideal amount of surface area and cushion.
  • Debossed channels allow airflow to aid in cooling.
  • Arm pad width adjusts from 142mm - 255mm by utilizing one of the two included wing options.
  • Arm pad stack up to 60mm and reach by 50mm
  • All hardware is corrosion resistant stainless steel.

Released 12 months after TriRig Alpha One...super unique. Looks like a nice bar though.

It does look very nice. Perhaps it has different features than the TriRig version?

I really dig these, and I think a lot of thought has gone into the shape of the aerobar extensions. What is the approximate cost? Couldn't find that info on the site.

I get that you could see it this way...it did take him a long time to bring these to market...but he had these on Factor bikes in early 2017...so I think it was a unique idea...it wasn’t “born” from seeing anything from tri rig...I don’t believe

I know I saw images of this bar back in May of 2017 on the factor bikes...

Does anybody else think that 110mm rise with flat armrests is a little too much?

I have evo110 on my vuka stealth without any issues and you can only add about 3° of tilt up or down and it's perfectly fine for me

Speed kills unless you have speed skills!!!

These look Super interesting and timely since I'm thinking about building up a new bike.

Any idea on when they will actually be available for sale?

Any other specs you can share? i.e. weight?

"110mm rise to promote aerodynamics" is probably not true most of the time. I am in the Desert Dude corner on this one after listening to him for years and seeing it with my own eyes in the tunnel a couple weeks ago. Higher hands are slower for 80% of triathlon speed riders. Now, as a fitter, higher hands are almost universally more comfortable, but I have scaled back a bit and now try to limit riders to 3-5 degrees of tilt and only if they are significantly more comfortable there than flat.

On the high hands issue - I know that higher hands might be slower, but besides comfort, isn’t it also easier to faciliate a “shrug” with the hands/arms angled slightly up? My thought - based on fit changes and speed increases this year - is that if you’re getting your head significantly lower than you’re probably more than offsetting the increases drag from higher hand position.

“Triathlon speed riders”. So would this mean that a 30mph wind tunnel would not be valid for slower riders? As in, “the air flow at 30mph reacts differently than the air flow at 20mph”? Like, “at 30mph, hands high pushes the air around your body but at 20mph, the air reattaches before it gets to your body”?

Yes, lots of questions and assumptions without being a physicist like many people on this forum.

Different yaw angles at 20mph than at 30mph.

110mm tested fastest for me. It is not really a very extreme hands high position. But it is about the max you can go with and still be UCI compliant.

But you do need to find a way to angle the arm rests, I bought some 10 degree wedges from a chap in the UK who 3D prints them for most of the common base bars. The wedges made the 110mm rise very comfortable.

Huh. I'm trying to square ^that^ generalization up with the generalization ("all" ... "certainly" ... majority" ... etc) from ERO at http://www.ero-sports.com/...r-more-comfort-speed:

All the aero testing we've conducted with different arm angles, there's certainly no doubt the majority of athletes, the overwhelming majority, in fact, find an aerodynamic savings from an upward tilt to their forearms. Sometimes it's a modest gain; other times, the gains are quite significant...almost unbelievable. I decided to test different forearm angles for myself. Below you'll see the three different arm positions I tried both for comfort and aerodynamics.

That's what I mean. If they are going to have 110mm extensions, the wedges should be standard.

The purported reason for the discrepancy is that Jim tests only on the track at low yaw, and "high hands" are not beneficial at higher yaw.

Oh now you've gone and done it--bring on the yaw debate.

I asked Jim if he could explain in the Rohan Denis thread after winning the tt world title why the cyclists with limit fit restrictions why they seemed to be adopting raising the hands more so than the top Ironman athletes but he chose not to respond. I'm curious because I've just gone up and won't go back down more based on comfort.

1. it's more comfortable

2. it's faster, for some

3. it "shortens" the arms, ie. they're not quite as maxed out on the UCI reach requirements. There's a stack limit too though

raising the hands in and of themselves is not the point. That's why high hands are slower for most.
