|number of spokes: advice wanted !||Gianicolo|
Jun 21, 2003 2:25 AM
I'm about to make news wheels. As I want them to be light I've choosen for Ambrosio Formula 20 Crono rims (340gr) and probably I'll take DT Swiss Hügi 240 hubs.
They're for every day use, even on some cobbled road.
I'm a light rider (58kg).
Is 28 spokes front and rear ok, or should I go for 32 spokes?! I saw Popovych used this rims in the Giro with 28; but a pro rider can change wheels every day, isn't it?!
Thanks for the advice.

|I think at your wieght you would be fine with 28 spokes. Get something like DT Revolutions or Sapim X Rays. They are light and really strong too. The only thing I would be concerned with is that you say you ride on bad roads. How is your riding style over those roads? Are you relaxed and loose over those roads or are you tense, worried about falling, and therefore stiff on your bike (bad for wheels)?
If they are for everyday use and not a race wheel, the difference of adding 4 spokes to each wheel should only make about a 20-30 gram difference per wheel. 32 will be stronger... you have light stuff to start with... will adding 60 grams (max) to the total wheelset weight concern you if they are your everyday wheels? If not, be safer and go 32. But I don't think 28 is unreasonably light for a rider your size.

|Thanks for the advice...
About riding on bad and cobbled roads: I'm used to it and love it to. So I'm relaxed while riding over Kwaremont, Mur de Grammont, etc. (if you know these roads, famous from Tour of Flandres). I'm taking them at high speed (40km/h, if it's a flat road) so I have less shocks...
Thanks anyway. I'm going for 28 spokes.

|Cool! Nice area you are riding in!
I ran a model on a website building a pair of wheels with 28 and 32 spokes. (The rims in my model were different, but that didn't matter as the only thing I changed was the number of spokes.)
The 32 spoke wheelset came out about 50 grams heavier than the 28s, so my guess of 20 to 30 grams a wheel was about right.
But at your weight, 28's should be fine.

|Can you give the URL of the website you're talking about?! Sounds cool...

|I actually just ran a model on wrenchscience.com. They didn't have the rims you listed so I ran the model with Velocity Aeroheads instead. It shouldn't make a difference as the only weight change I made was the amount of spokes and just subtracted the weight from each. But the other link someone posted will work just fine too.
