Hambini's Sunday Roast: $800 CeramicSpeed OSPW

[@Hambini]

Note there is an error. where I referred to the retracted cage position. That should be the position with the most slack. I will get the hairdresser to tie me up and discipline me for my disobedience.

When I was done with the drive I had 3/4 of a tank of gas after not stopping to refuel. This guy with the name I don't remember or GAF about is a fucking HERO !

Hambin, at 9:29, that position would seem to be for high speed, not low speed? When the derailleur is in that position you’re likely to be in the 11 or 12 unless you’re running a really big chainring to offset the cross-chaining losses.

It makes sense that the biggest aero gains will be in the cleaner air at the front of a bike, so things like an aero helmet, front wheel and forks. The potential gains from secondary elements in dirty air, like the rear cage, are miniscule, yet that won't prevent some fools from (literally) buying in to the marketing hype of crappy pseudo-scientific products like this.

[@Hambini]

I couldn't have worded that more succinctly if I tried.

[@glennoc8585]

Think of a sine wave in electrical current flow and then observe the unbalanced wave form after it passed through a circuit. A similar thing happens to an air stream on it meets that spinning chopper of a crank arm, leg, & foot. The air would have to ' Smooth out by the time it meets the 'hangar fairing'. Id like to see a modelling or even a good old smoke test.

@hambini the 'dirty air' scenario is actually more ineffective than you explain with Shimano. DA and Ultegra (maybe 105?) are all Shadow-style. The mech sits directly under then cassette, not outboard as older road rear mechs did. So it's not only the shoes, but the entire bb and crankset that the rear mech "drafts". So it's constantly in dirty air.

[@owensnicholas]

I don’t think ‘shadow’ derailleurs make a difference here. Shadow design or not, the cage is in the same place, under the cassette. It has to be. It was the parallelogram that was moved inboard.

[@osh241]

As soon as I seen this product I was awaiting Hambini's roast.. let's go!

[@richdyer2000]

The minimum advertised price is because Ceramic Speed products are what economists call Giffen Goods: The higher price actually increases consumer demand (or, at least makes them appear desirable). Giffen Goods are a special type of Inferior Products.

[@davidburgess741]

It seems to me that at least you would be getting the product they advertise. No nylon bearings and silly flexible cages as another brand was shilling. The gains would be microscopic as the Demitriev number would be crazy in all that dirty air. I'm waiting to see when the aero chain comes out! This must surely be next for people with way too much money!

[@Reanimator999]

​@RollinRat Obviously they're making a lot of money through their day job or business to support their "cool" amateur athlete lifestyle, but I don't know how many of them are willing to give up their job/business for a full-fledged contract if there's one. I understand that those people are competitive and being admired for taking upon a tough sport, but deep inside I think those triathletes are insecure in some ways.

[@Xarx42]

One thing you forgot to mention: yes, the ceramic speed pulley spins so nicely in comparison to Shimano or Sram, but the simple reason behind is the lack of sealing of the bearing. So if you really buy this thing for the (marginal) gainz you need to take it apart and clean it on a regular basis... :D

[@Hambini]

have you ditched that mask yet

[@agie170hss2]

Someone should just put a bike (with rider pedaling) in a wind tunnel and wave a smoke wand around in front of it. That would (IMO) quickly illustrate what is important in aero, and what isn't. I'm guessing: the rider's position and helmet/clothing (including shoes/socks), the front wheel/tire combination, possibly a portion of the bars and hoods. I'd be willing to bet that the potential gains behind/below those items decreases to near zero in short order for 99.9% of the riders on the road. I say: spend the $800 on a bike fit, a tight-fitting jersey, keeping the drivetrain clean, and absolutely some flowers for the hair dresser -- the gains will be far more significant (and fun).

[@j.dietrich]

A smoke wand doesn't give you quantitative data, that's why we use load cells to actually measure drag. Drag2zero will happily rent out their tunnel to anyone - a lot of serious amateur riders are using the tunnel to tune their setup, which at £1200 a time goes some way to explaining their bank balance. Everything counts, it just counts in proportion to CdA. There's not much point in faffing about with go-faster bits if your numbers aren't pinned on properly. With that said, very small drag savings can be highly relevant in time trials or sprints. Much as I respect Hambini's credentials, I'd personally be a bit reluctant to dismiss this as useless. The rear mech is in an incredibly complex area of flow and properly weird things can happen there, especially with a disc wheel. We know that oversized pulleys provide a small but measurable drag reduction, so it's totally plausible to me that this setup could deliver a useful drag saving in some circumstances. Obviously it's totally pointless if you're a lardy MAMIL, but it might buy you a few tenths if you're a properly fast tester with a properly fast setup.

[@Reanimator999]

@@j.dietrich The whole marginal gain obsession props up companies like Ceramic Speed to come up with such unproven product. I know marginal gains are big deal to time trialists, but has anyone won the competitions consistently with OSPW? Even if one has advantage of drag reductions here and there, it's kind of pointless when that rider competes with others with the same level of fitness and unpredictable wind change (if outdoor).

[@eberger02]

Road bike drop outs are 130mm. Minus a bit for nut etc. Q-width on road bike usually 150mm. Haven’t measured it but looked on 2 of my bikes with shoes attached. Looks to me a pro with a big front chain ring wouldn’t have feet in front of the derailleur but rather the crank, which could be aero, because they can use the 3rd or 4th cassette cog. Mere mortals with only a 53 up front & normal cranks though… suspect what minor benefit there is would disappear when used by people who don’t get stuff for free. Think I saw them in the Giro D’Italia on Israel Premier-tech TT bikes last Saturday BTW, at least Alex Dowsett’s. Nasty bump at the end though, so I don’t know how big a chainring he dared use.

But..., since we are talking low airspeeds when we are talking bikes, I tend to believe that pressure differences are less important than the "smoothing" of the airflow and that the spinning pullywheels are removed from the direct airflow. Well I do not think it matters much anyhow, except lining the pckets of the shareholders. I would mount a static surface on the lower arm, ahead of the shifter... (I do not care about those old men in UCI).

[@costelloandsilke7321]

The "it's expensive so it must work" is a form of "expectation bias". As you say Hambini, the airflow in that area is so disrupted that any gains from fairing the derailleur pulley really must be miniscule. A bit of a lighthouse in a bog product.

[@HappyDuude]

I think you've suggested before, feel like there's a good aero 101 video for everyone - going as basic as what percentages of W x H are made up of rider, wheels, handlebar -- so people can put figures to the maximum potential gains. Eg handlebar makes up (plucking number here) 5% of total area, so your maximum gain, if achievable is capped at 5%, Vs wheels, Vs rider. Basically a basic video showing for each part that makes up the frontal area, what that maximal gain could be (in that forward plane only).

[@ooitzeyang]

The margins on these things even on the dealer/retail side is amazing. As a shop I'd rather swallow this drivel full and sell them than anything else.

[@armadillito]

I wonder whether you could simply fill in ahead of and behind the jockey wheels on a standard sized cage?

It doesn't take any analysis to realize that the OSPW cover will do nothing. Just compare the area of the cover to the frontal area of bike and rider. The cover is probably 0.3% of the total area, so if it reduced drag on the OSPW by 50% that would be about 0.28 watts at 32kph

wasn't one of the arguments when the first oversized pulleys launched that even though they where bigger the efficiency savings of the rounder chain line where greater than the extra drag the bigger pulleys caused? for 100 dollars? maybe looks funky, 800? you can get a full bike fit and aero clothing for the same price wich will result in way better measurable performance... €4500 for an sl7 framset seems reasonable now

[@Hexsense]

Still in the same principle. Back end of the bike got dirty air. With dirty air, it's better to minimize surface area. Oversized pulleys, covered with fairing or not, still have more surface area than regular pulley wheel cage.

[@Hexsense]

So, should I pay any attention to chainring aerodynamic at all? It's kinda in front end of the drivetrain. It hit relatively clean air as it's not directly behind front wheel and down tube. Would Rotor aero chainring vs Dura-ace's 4 arm chainring aero difference measurable or negligible?

[@gilleek2]

You know the fairings/covers that go over chains and chainrings on kids bikes? Would that not be a better idea for smoothing out air flow in that area of the bike? Air is already really turbulent but it would cover a much larger part of that dirty air going from front edge of big chainring all the way back the the cassette. Would look shit but if you wanna go fast and you're not governed by UCI limitations like in Ironman racing that looking shit takes a back seat

[@Hambini]

I think the problem there would be kids bikes tend to be single speed so you don't have the problem of the chain slack. I think the future is likely to be epicyclic gearboxes inside the hubs.

[@gilleek2]

@@Hambini surely with all the great minds inside Ceramicspeed and Drag2Zero they could design something to accommodate chain slack.😀 Couldnt you also just make that cover larger for the slack? Absolutely those gearboxes should be the future. I'm sure the UCI wouldn't allow it though.

low friction requires a small bearing, that in turn requires as little axial load as possible. To achieve that, you need a small jockey wheel.

I would take issue with the losses caused by the chain angle, since that part of the chain is not under tension. A larger bearing for the pulley might add weight, which I don’t consider a problem. I do see the advantage of less chain articulation. . . a good reason to ride on the big ring and a larger cog. . . one of the reasons I ride a 56-tooth chainring on my TT bike, aligning with 16-17-18 teeth in the middle of the cog to maintain a straight as possible chain line. So far, no Ceramic Speed ANYTHING for me. At 77, probability zero. The only way to test the aerodynamics of the cage would be in a wind tunnel. All else is mere speculation.

[@davidburgess741]

I've got a 52x19 on my track bike. That's as marginal gainy as I'll go. The Tri bars on the road and tight clothing are more than a marginal gain. To be honest, the big chainring just looks cool on my fixie! At 63 marginal gains matter less and less! No hills around here. Nothing with less drag than fixed gear drivetrain.

As a bike shop owner my best advice for getting to the finish line first: Use good tires which do not go flat Buy a bike which goes in a straight line so you do not crash Get fitted so your ear(balance point) is over the axis of steering (head tube). Learn to ride rollers so you learn to steer with your butt not your hands.

[@DaveCM]

Question: On a TT bike, couldn't the benefits be optimized given the proper setup and the proper conditions. For example, the TT specialists will put on massive chainrings and setup the gearing so they will be predominantly in the middle of the cassette to minimize losses. So, on a flatter TT, wouldn't they see at least some marginal benefit from this? Or at least have the best chance at being beneficial? Granted, that would probably inspire some people on the group ride to buy them. Edit: One more thing occurred to me watching the rest of the video. There is no way for them to prove the benefit of their product. Even if it worked completely as promised. It would be such a small gain that it would be well within any margins of error in an applicable aero testing. At least that is my view of it.

[@Hambini]

In turbulent or dirty conditions, the aerodynamic profile generally doesn't work. A circle has similar drag. The purists will go for the smaller object rather than a fairing
