So i want to buy a new rear hub but my current hub is like a cheap unpopular hub and i couldnt find it on spoke calculators and the only info i found about it i found was this. (They probably should be a picture down)
How do i find a hub compatible with my rim and spokes and with the same dimensions as my current one? Please somebody help me becose this unsealed hub pisses me off an losens all the time.

Heres Some Links and Pics.

As long as its a 36 hole rim and a 36 hole hub they will all be compatible. Just use a popular hub that is listed on the spoke calculator apps/sites.

you'll just have to look, sometimes hubs will have some dimensions to them. I'm not sure what some of those abbreviations mean but the O.L.D. is the hub spacing (rear bmx is 110mm), the F.T.F. I assume means flange to flange, so the offset is probably 29.5mm or close to it, and by process of elimination I assume the P.C.D. is the flange diameters which would be 58mm

that's a pretty high flange hub, most freecoasters as long as the flanges are the same size would likely be the same or similar enough to work, but I can't find any modern cassettes with both flanges that high so you'll probably just have to get new spokes if that's what you wanted to avoid.

if you're thinking the hub dimensions HAVE to be the same size to fit your spokes and rim, no that's not true. you can get new spokes the correct size and put whatever hub you want on

I found a hub that i can afford but there are no dimensions on the site and i cant really figure out the spoke calculator. Can someone that smarter than me check i would appriciate it alot.

My rim isnt on any spoke calculator but heres a link.

Heres the hub

and i cant find any dimension about the spokes :/

186mm spokes, 184mm will probably do it just fine too. But, you'd be better off buying a wheel. Spokes will cost you money, so will paying someone to build the wheel for you. For probably less than that you can buy the United supreme cassette wheel, and have a better rim
