Spoke Length...


RyanRs

Recommended Posts

I no i shuld go down halfords and use the spoke measuring tool, but its a wee journey from my house and i gather one of you might no the answer here, so ill ask....

I would like to no what spoke length(s) i would need to lace up a King ISO hub to a V!Z 46mm 26" rim (the new hexagon cutout one) 4x stylee err 32 hole.

4x would make the wheel flex like a mother trucker!!!!

i have started using x2 drive side and radial non drive and same for the front, makes landing feel harder on your wrists but deffinatly increases power out of the rear wheel its nearlty like 4 wheel drive action!!!!!

Hmm waynio. Sorry to piss on your fire, but maybe you're just landing harder.

Straight from Jobst Brandt:

A 290mm spoke is 3% stiffer than a 300mm spoke of the same type. Since spokes stretch elastically about 0.1mm on a hard bump (not ordinary road ripples), the elastic difference between the radial and cross-three wheel is 3% x 0.1mm = 0.003mm. Copier paper is 0.075mm thick, and if you can feel that when you ride over it on a glassy smooth concrete surface, please let me know. You have greater sensitivity than the lady in "the princess and the pea" fable.

trust me mate its not about how stiff "A" spoke is!!!!!

Radial is the stiffest you can lace a wheel if you do not believe me then my boss as an EX PRO racer is a complete arse then eh????? i do not think so. ask tarty??? a less crossed wheel is STIFFER. the more you cross the less stiff it is. look at a bmx wheel that is 4x :D :S

Waynio.....................

trust me im a bike doctor iv been in the trade for 5years............and built wheels since i was 16!!!!! I can feel a difference, if you cant you havent ridden enough. iv ridden trials for nearly 5years too. im sorry but i dont want this to seem harsh but i am speaking the truth and from an exp[erienced road racer where stiffness and acceleration is quite important i doubt my boss who has been in the cycle industry about 25years would be wrong???? or would you if you have 1/2/3/4/5 years???? experience wish to differ???

Never really thought about this much before, but I have read statistics that a radial wheel is 15-20% stiffer SIDEWAYS than a 3x one.

When it comes to torque... I would have thought more crosses would equal better power transfer - since the spokes are more tangential to the hub. I feel a doodle coing on... :-

Its pretty much impossible to tell on a bike which wheel is stiffer, unless you keep EVERYTHING else the same, and change just the wheel. Is that what you've done Wayne?

I *think* i get you with the torque thing. Its like the hub is pulling on the spokes to turn the rim, which can be done by a single spoke. much like a dog on a lead :-

Whereas the radial requires a all the spokes to be tight, and pushes the rim around.

Thats the way im thinking anyway. As for the stiffness thing, I have no idea. I used a 4x for my rear wheel because I was told it was the strongest type using

I've noticed where the spokes cross, they bend in a curve around each other, if you load it its going to straighten out a bit, so the fewer crosses, the less give there'll be in the wheel, which would explain the harsher feeling sir waynio was describing :-
