Wanted: Aerospoke

So after asking on this forum, apparently aerospokes are crap and they're painted shitly, so do yourself a favour and sell me yours. Unfortunately ASM is all out. :D

Anybody got one they wanna offload?

for £300.00 i'd just get a new one, his best offer limit seems quite high :(

Buy a deep v on a phil wood or something, similar price (maybe cheaper I can't remember what a spok costs lately), more aerodynamic, lighter, and a lot tougher......whats not to like ;).

how much are you willing to pay?

I very much doubt it. The reason wheels have relatively high drag is because the spokes are cylindrical, and cylinders and spheres are one of the least aerodynamic shapes you can get - even tiny ones like spokes. Aerospoke spokes are designed as symmetrical aerofoils. ie. very streamlined. I think what you mean is that aerospokes are not great in cross winds, which is true - not because they are not aerodynamic, but because wind hitting a symmetrical aerofoil at an angle creates lift - ie. each of the spokes will be pulled in a certain direction - but not neccessarily slowing you down. Could even help you. So they're probably very good in velodromes, and nicht so gut in windy places.

Phew, explanation over I think. I noticed somewhere else that you'd said aerospokes aren't aerodynamic, thought I'd put it straight now. :)

30g drag more than a 30mm 'standard' rim at 0deg yaw at 29mph, getting worse as yaw increases.
Aerospoke aerodynamics.. meh.

Well, I'm happy to stand corrected, but that page doesn't say anything about the spokes on the standard rims. ie. how many?, bladed? Or did they just test the rim itself? The drag-yaw relationship is because of what I explained though :) Partial win.

Anyway, whatever, I don't care, etc. =p

how much again?

how much are you willing to pay?

depends entirely on the age/condition etc
but enough to make you sell

what's the max? my mate has a pretty decent one. i could check for you but would like to have an idea first.

but if I give you a max and you tell them that it's what they're gonna expect ;)
i'll say £180
now i'd be very willing to pay more than that but i'm not looking to make an offer so good it'll convince someone who isn't looking to to sell, if you know what I mean...

ive know someone who might wanna sell if you interested . ill find out .

Nope their aerodynamics are shit, there is a lot more to aerodynamics than just having a symmetrical aerofoil shape :/, I meant exactly what I said and I stick by it with the tests to back it up until you can prove otherwise :).

pm'd you HenvY, the 'spok on Ebay is brand new, never been fitted/used so it's in that condition, same as you'd get it new from BLB or anywhere else... plug

yep but they look good. if you cared about how fast you went you'd be training instead of on the forummmmm
pm'd you henvy.

Rest after training is how you get faster. :P

I couldn't agree more, rest...lots of rest, and beer, for carb-loading purposes of course.

Yep.. beer, pizza, porn vids, forum posting, midget tossing. I really don't have time for training with a rest schedule this dedicated.

Aerospokes are good at maintaining velocity. They act like a flywheel. It's an effect that you actually notice on London roads, unlike the aerodynamic benefits of most other silly wheels. :)

You'll find it harder to accelerate, murder in a crosswind or headwind, but once you get up to speed, you'll find it easier to stay at speed. But it works the other way, you'll also notice the increased weight and momentum will make it harder to slow down as well!

porn stresses me out these days...just getting far too hardcore but i see that you are smart and stick to the vids rather than surf the net - dangerous and rather worrying it is these days

Let's not be patronising James, I study aerodynamics, and actually, as far as the spokes are concerned, it IS as simple as using symmetrical aerofoils. Where it gets complex is the interaction between the flow coming around the rim and meeting the spokes. I don't understand the dynamics, and judging by your comment:

Nope their aerodynamics are shit

nor do you. As far 'tests' backing it up go, if you mean the page hippy linked to, these are not exactly clear. And even so, if you'd looked properly, you'd see that the aerospoke's performance is far from 'shit'. So, let's agree to disagree for now.

Or you'll get some of this:

yaw(n) :p

spam. ban this spoke-whore :)

Bollocks! I hate my spok! The only reason why I haven't sold it is because it's so awfully painted.

I'm going to strip it when i get back to london.
