ok so im a little imbarrassed about this.ridethelightning wrote:I just laced one recently with a saint front hub.Quokka wrote:Anyone measured the ERD of these? Is the 468mm from the manufacturer (the 19") correct?
I must have made a mistake with the calc somewhere, as the spokes were a couple mm on the short side., still workable though.
I was going on ERD 471mm, but i dont know if my error was with the rim or hub measurement, or both
depending on the nipple gage, it might make a significant difference, cause the rim holes are only ~5mm for 12g spoke nipples, so a larger nipple may sit a little proud in the hole,meaning the spokes will need to be slightly longer...unless they are drilled out slightly so the nipple sits lower.
if you measure the ERD with DIFFERENT size nipples, that can make it off too, i think thats also what i did.
however Ozman found his calc out by a couple mm too long,(see his post earlier) with his mxus hub, he was working with what the manufacturer told me- 446mm.
I will re-measure the ERD of both sizes shortly and post results.
im guessing less than or up to $30 for 2 rims to QLD.Mad Huey wrote:Can u price me on an 18" and a 19" posted to Gold coast Qld. And what sizes will they equate to in MTB RIM (eg24"or 26") when fitted with tyres. Thanks
Quokka wrote:Half way through lacing up a front 19" rim. With just the 2.75/3.00 x19 tyre its around 600mm in diameter. With a tyre as well it will be close to 25" tall I think. Not sure about the smaller rim. 600mm in diameter is just the tube
Sounds like holmes are getting more organised.Quokka wrote:For the front wheel I am building I have used 12g spokes from Holmes hobbies. The left spoke length was 221mm and the right is 223mm. I have used a hope pro 2 Evo hub. I had to enlarge the hub spoke holes to 3.5mm using drill bit and cordless drill. I am still waiting on my spoke wrench so I am not sure yet if the spoke length is correct. If I was to make the wheel again I would consider using 13 or 14 g spokes as their are some gnarly spoke angles using the 12's. But the wheel looks super tough and I reckon I won't break it any time soon. I am running Shinko 241's but they are still on their way.
The rear wheel I am building is a Cromotor v3- from Zelena. Spoke lengths for that have come out to be 130mm. When I build the wheel I will post a revised spoke length if its dodgy. Both rims are 19"
On another note the spokes from Holmes hobbies were amazingly fast, took around 10days from order to having them
RTL, I am running vee rubber v308's which are available in local motorbike shops in oz (my shop ordered them in for me from oz distributer) they are sold as trial tyres but look similar to the shinko 241's. Fit the 1.4" wide rims perfectly and performance wise very happy.ridethelightning wrote:btw.
anyone who has found a LOCAL source of tyres for 18/19"x1.4 rims, that is reasonably priced, please mention what and where in the thread here.
