Pet paws & turned-in levers are out, however ultra-narrow super-aero bars are in – and TRed’s TOOT Racing has a UCI-compliant Ashaa RR resolution. A bar first developed on the monitor, the Ashaa RR is a customizable super-narrow, flared & ultra-aero street handlebar designed to get you in probably the most aerodynamic place, with out sacrificing security or management. To shortly get bars into racers’ arms, Toot 3D-print the handlebars to suit the rider from chrome steel for max power or titanium for added weight financial savings.
Or when you’ve got a bit of endurance, weight weenies will have the ability to get an excellent lighter carbon Ashaa RR aero handlebar possibility quickly. And it’ll be rather a lot cheaper too!
TRed’s TOOT Ashaa RR 3D-printed aero street handlebars
Aero positive factors are all the pieces as of late. And refining your place on the bike has all the time been one of many easiest and handiest methods to save lots of watts. As a lot as manufacturers prefer to sweat over the incremental enhancements of hidden nipples or tweaked rim profiles, the rider nonetheless accounts for many of the drag on a motorbike at velocity.
First developed on the monitor, then refined on the street
TT & Triathlon racers have lengthy accepted that refining their hand place has been one of the simplest ways to go quicker. However street riders have been caught with standard drop bars, because the UCI continues to ban any alternate hand positions.
The newest UCI guidelines eradicated the “pet paws” or “invisible aerobars” place for actual security issues as riders weren’t truly holding onto their bikes within the bunch. So riders opted for turned in levers to maintain their arms “on the bars”. However once more, light-weight carbon bars weren’t designed for metallic clamps on the uncommon inward angles, in order that acquired banned too.
Aspect observe: I’ve each damaged a bar off below the clamp in a small crash racing. And eliminated a ‘manufacturing facility set’ lever to seek out the carbon bar crushed below the imperfectly put in metallic lever clamp. So, I get the priority.
However professional racers need to go quick. And newbie riders prefer to emulate their professional biking heroes. So, there must be an answer.
Italian bikebuilder TRed’s part division TOOT has been engaged on alternate ergonomic and aero handlebars for a while. We final caught up with their Ashaa bar on the monitor a pair years in the past – when the patented it. Up to date extra final summer season. However now, with extra UCI restrictions on street racing, the customizable aerodynamic nature of that unique bar looks like it might repay much more. Each for professional and newbie racers alike.
This model then was developed and examined on the street & monitor with Argentinian former professional bicycle owner Facundo Lezica working with TRed/Toot’s Romolo Stanco. Then, confirmed with present Madison World Champ Jan-Willem van Schip.
What’s distinctive in regards to the TOOT ASHAA RR bar?
TRed calls the TOOT ASHAA RR, the “first handlebar to ensure an especially aerodynamic place with out compromising management and security.” That will get to addressing all the UCI’s issues, it appears.
It’s constructed round a novel slim geometry that places your arms additional ahead, increased, and nearer collectively, than even a slim standard 38-42cm bar (all dimension mentioned are measured center-to-center) on the hoods.
Word: UCI regulation dictates allowable exterior dimensions for racing eligibility, which is why Toot lists these.
Extremely-narrow and complexly curved
Which means a protracted bar Attain of 118mm and deep Drop of 105mm. That’s designed to suit along with your similar stem – your arms attain extra ahead as arms come nearer collectively.
Width is wildly slim at round 24cm extensive on the hoods, that are barely raised above the stem. Then, they lean the bars themselves in round 5° in the direction of a clamping space, additional rotated in one other 5-10° to securely interface with turned-in levers – ensuing in the long run of your hoods being 19-21cm extensive.
Wow, proper?
Tremendous slim.
However the Ashaa RR street racing bars additionally characteristic dramatic (for the street) ~20° flare for a steady sense of management. Formally it’s not “flare” as Toot explains that it’s a non-linear curve (a key a part of their patent). There are only a few actual straight angles on the bar. However the result’s that it places the ends of the drops 33-35cm extensive. And the roomy drops characteristic angles to supply a natural-feeling place and loads of stability.
It’s actually a dramatically totally different place – one thing in between common drops and aero bars. But despite the fact that you’re slim and leaning ahead, the rider can preserve their arms firmly held within the acquainted steady place of a dropbar for max management.
How A lot Quicker?
“Each with high and low grip the place is steady and comfy with excellent dealing with. From the info collected with the Velocomp Aeropod V5 pitot system – which detects the CdA in actual time – my general aerodynamic effectivity improves by greater than 4%. Which means that if with a standard 40cm handlebar at 320W I’m at 45km/h, with the place that this handlebar permits me to imagine (each on the controls and on the handlebar) I experience at 47km/h maintaining the levers completely aligned with the deal with. And keep in mind that the extra the velocity will increase, the broader the hole between the 2 values is.”

3D-Printing Tech
After all, 3D-printing allowed TRed / Toot to shortly flip an concept into actuality. But it surely additionally means they will customise the precise form to greatest match riders individually – very similar to we see in customized aero bars. However it’s a bit less complicated right here, Toot refines a proposed form with a customized bar purchaser, then mocks-up a plastic dummy for closing testing earlier than printing a metallic bar.
Their commonplace 3D-printed Ashaa RR is constituted of 316L chrome steel, which permits Toot to tailor power & stiffness to particular person rider wants as properly. They are saying that may differ complete bar weight from 360-480g.
They print every metal or ti bar in two interlocking halves, welded collectively within the center (see inside, between the place the stem clamps), after which floor completely easy for a 31.8mm clamping space.
How robust is that?
It is a 3D-printed Toot Asheeta metal monitor bar I noticed after an enormous crash into the boundaries final summer season at one thing like 50km/hr, so arduous that if folded-in the downtube (however didn’t crack any tubes or welds). And the bar is simply scratched. And the experience walked away, though bleeding and lacking some pores and skin.
All bars are additionally suitable with full inside cable routing. In truth, Toot can even make you a customized carbon, aluminum, or titanium stem in any desired size to work with the commonest inside routing methods.
Totally customizable in 3D-printed metal
They 3D-print the Ashaa RR in chrome steel in Italy on the College of Pavia. And supply both on this inventory geometry. Or you may get a completely customizable measurement and form to make it match completely in your individual arms and towards your individual forearms. Importantly, all customized bars are additionally stress and fatigue take a look at licensed by a trade third social gathering.
Toot even says that it could “even be custom-made for gravel“. We’re fairly curious what we’d change to experience off-road. However at this worth, they’ll make it no matter form you want.
Lighter weight in Yottalight 3D-printed titanium
The bar can be out there in the usual dimensions because the Toot Ashaa RR Yottalight. 3D-printed in titanium in Germany by ApWorks (a division of the Airbus group) to save lots of weight with out sacrificing power. Weight financial savings over the optimized metal model is alleged to be about 15%.
Extra reasonably priced AND lighter in carbon
If you wish to save weight AND some money – opposite to all the pieces else within the bike trade – you possibly can even decide carbon, as an alternative. However you’ll have to wait a bit of longer. Toot manufactures the carbon bar with extra standard molding methods. Though for now in 3D-printed metal molds in Italy for the early manufacturing. So solely the inventory measurement and form is out there. The carbon bar can be 2cm wider with wider wings up high, providing a bit extra common attraction.
Toot Ashaa RR – Pricing, choices & availability
Primarily 4 variations of the brand new Toot Ashaa RR aero street racing handlebar can be found. Commonplace geometry in 3D-printed metal for 1390€. Commonplace geometry in 3D-printed titanium or customized geometry in 3D-printed metal for 1990€. Or ‘simply’ 429€ for the carbon bar in case you pre-order now.
The 3D-printed bars are all made-to-order with a max 21 working day lead-time for traditional geometry. Toot presents the carbon Ashaa RR bars as a pre-order till mid-February, with the primary deliveries slated to start on the finish of Mach 2024.
What’s subsequent?
One piece 3D-printed metal or titanium handlebar+stem cockpit combos?
Yeah, Toot is already engaged on that too. It is a customized Ashaa RR 1-piece cockpit in 3D-printed titanium!
