Spotted these a week or so ago, I'm not sure if they've been covered here or not:-

By 'Cyclings Bugatti Veyron' I mean a product so ridiculously over engineered yet still impressive in its design and end result.
Ps - UGO, what's your thoughts as the resident wheelsmith? Fancy knocking a set up @ $7000?!!!

Not much thought went in the design of the rear hub, which has a very narrow flage spacing. This leads to a very weak wheel with the vast majority of rims on the market and probalby worth building only with 60 mm plus deep rims.left the forum March 20230

Interesting analogy. The Veyron was a project that was about being the best. But not in the way that a rocket was better than a biplane. Just the absolute best. 95% of the performance was available from the top end Ferrari et al.
Will these add 5% to a pair of £600 King hubs? I doubt it very much.My blog: http://www.roubaixcycling.cc (kit reviews and other musings)

Impressive to see the engineering though.
Reminds me of a thought that passed through my head, while on one of those long rides where all sorts of crap passes through...
Impressive though that all the engineering and finely balanced parts are in the hub, - the wheel as a running unit is never balanced.
On a car, you get your wheels dynamically balanced now and then (if they aren't balanced, you can feel a vibration through the steering wheel, - especially with a non power steering system). Of course, it isn't the wheel you're getting balanced, - that's already finely turned and balanced during production, but the tyre. The tyres aren't a regular and homogenous piece of kit. And I've wondered, during these moments of rural loneliness and futility, why cycle wheels aren't balanced as a tyre/wheel unit. On a fast downhill, with a corner coming up, it would be nice to know that your wheels aren't upsetting the balance of the bike.0 -
Absolutely. I'd imagine that King hubs are as finely balanced (at least as far as they need to be) and that other hubs might be as friction "less" as required.
You'd need to partner these with some mega rims and have the valve balanced using minute measurements. Even at TDF speeds a minor imperfection won't be felt. As impressive as these are I can see little benefit.My blog: http://www.roubaixcycling.cc (kit reviews and other musings)

Perhaps these are the hubs that this guy is (unwittingly) using:

Motorcycle wheels are not dynamically balanced as it's not as critical on bikes as it is on cars. Not entirely sure why though, possibly something to do with the fact that front wheels on cars have a degree of toe in.0

Oh yes they are. Maybe you should change fitters?Motorcycle wheels are not dynamically balanced as it's not as critical on bikes as it is on cars. Not entirely sure why though, possibly something to do with the fact that front wheels on cars have a degree of toe in.0 -
Haven't run a bike for a few years, but the place I used to use would statically balance them. Friend of mine that works on race bike suspension told me there is less need for balancing on bikes so static is ok.

As has been pointed out they most certainly are. I've ridden a set that weren't and it's really not good!Trail fun - Transition Bandit

Does he work in splendid isolation? You only need to pop into the Pirelli service area at the British Superbike rounds to see that they most definitely balance them dynamically! (As does the guy who services my bikes!)Trail fun - Transition Bandit

A car wheel driving at 60mph will be rotating at ~840rpm, a bicycle wheel at 20mph will be rotating at ~250rpm - I'd imagine this would make the balance in a bicycle wheel less important than that in a car wheel.0

Wouldn't be a bike but a rider.
The bike is naff all .. A pro on a £500 carrera will still out perform any of us here.0 -
