Notorious Rims

Skidding does not put any extra strain on the rim, compared to standard use. There is a maximum strain point where you are resisting, yet the tyre still has traction. Once the skid starts and traction is lost. The strain drops considerably.

I doubt you can resist your pedals with more force than you could pedal them. If you then consider carbon rims are often ridden up bloody steep hills, by bloody strong cyclists using a 34:25 ratio. I really cant see how the force transfered by pulling a bit on the pedals even compares.....

But if if they kill you in the face with fire. I'll delete my post and deny everything.

Get a track SRM, then pull some Skidz, see if at the point described by SF above you hit a wattage above what you can exert pulling away/climbing.

It's actually (for a given value of actually) quite an interesting question, what is the power value of a skid.

I reckon the carbon rims would be fine, all that aside. You'd be nuts to buy them from BLB though as they (look identical too) the standard Chinese carbon rims you can get for a lot less cash direct.

A the very least it cant be any more than runnng a disc brake on a steep decent, and doing an emergency stop.

I rode a 11% climb on saturday (asending 110 meters over a kilometer or something), without a hint of brake rub. So my crabon wheels have past the first test. I cant believe simply skidding could stress the wheels more than a lump like me mashing up that cnut of a climb.

Heh, if in doubt get the rim built onto a disc brake hub and use a Velo Solo bolt on cog.

Lace it 36 hole/four cross, then try and destroy it with skidding.

Why will skidding be any different to pedalling hard?

Are you telling us that you wheel spin when starting on a regular basis?

thanks guys coz i m really considering getting it. it does make sense a lot more now.

as for the chinese rims and blb... i donno man i think they do look different if u look carefully. like even the carbon weave pattern is different. actually the chinese ones dont even have a weave

That's not true, you need to do some more research.

Chinese Carbon:

dammn that looked dope!

i donno man i take ur advice on board but it;s just i have held the blb ones in hald before they look pretty decent for the price but i donno about the chinese ones...

i do agree with you the fact that they are probably EXACTLY the same tho

Oh dear God no...

I did say for a given value!

It would be easy to calculate. You just need to calculate the force at which the tyre loses traction. This will depend the tyres coefficent of friction with the road.

I dont think its very much.

lazy answer.

A lot depends on rider position though, if you have your perineum above your top cap, then "very little" is the answer, if you are sat on the saddle then it's a lot higher.

True.

Varying from not very much to very little.

What if you are towing two small children behind you in a trailer?

How much are x2 rims with P&P, tho? (even without any risk of import duty)

And if there are any issues with them how much to return them?

Are there prices for rims alone, or built into wheels?

If built up, what spokes and hubs?

Just the rims I thought(?).

But I seem to remember farsport coming in at ~£140 a rim with postage. But that's just memory.

I'm not disputing that they're charging more for the same thing - just saying that you're getting a few benifits, which given the overall outlay actually might be worth it.

I'd still just go direct and get that sapim/novatech build I seem to recall them doing. Plus you can get a matt UD finish which (IMO) looks better than the weave.

EDIT: these 50mm at farsports are US$185 per rim... so that's £230 before postage.

Altho 2nd hand Reynolds are about £500: http://www.ebay.co.uk/itm/180858698502?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649&autorefresh=true#ht_712wt_932

£480 for a pair of rims, so build, spokes and hubs- call it £700 for a wheelset?

That's well into the realms of proper money- and proper wheels.

0W, no? Since there's no rotation during a skid, hence no power, only force.

I think you're right:

"In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity" (From Wikipedia).

In a very roundabout way I had been wondering what a track SRM records if/when you resist the pedals (or skid, but I'm not sure someone who'd put together a track bike with a power meter would skid a great deal).

whether or not these will be exactly the same as them blb ones i dont know. but u can certainly customize one from this buyer that will LOOK EXACTLY THE SAME.
total of 140 without tax. so worst come to worst you'll still save roughly 80 quid than buying from blb.. and i doubt the blb ones are 80 quid more in terms of quality actually.

but again i dont know because i've never seen these ones in life but the blb ones i held in hand were pretty decent stuff.

this seller even offers 1 year warrenty

Well fuck me, return to China ?

What sort of Twat are you ?

Are you related to the seller ?

just saying

i didnt even know about this till someone suggested these chinese sellers. whats ur problem? u related to blb?

You might be surprised- I bought a pair of rims from China, the brake track on them was usable but not totally flat.

I took some photographs and emailed them to the seller who sent me a new pair free of charge.

I had to pay postage, but that was a minor irritant.
