Answering your cycling questions

In order to determine the correct spoke length you need to know the size of the rim you are lacing it to.

Yes as long as the holes on the hub match the holes on the rim.

yes it would fit, if you had your rim and knew the spoke length, then yes we would be able to build it for you. it costs £34.95

You can lace this up to a 36h trippin rim. The spoke size will depend on how you want to lace it up, typically BMX wheels are laced 3 X in which case you would need 188mm spokes to do this.

such a simple short question, What size spokes and nipples?
the answer is too large for this reply.
What size spokes, is that length or diameter?
what lacing pattern are you using radial, 1x, 2x, 3x?
plain gauge, single or double butted or even Alpine spokes
Whats the intended use of the wheel?
whats your weight?
Whats your riding style, hard or easy on components/wheels?
several spoke manufacturers have on their web sites easy to follow online spoke length calculators. Once thats out of the way the other above questions need answers.

Hello,

I would recommend that you use 194mm spokes and lace this four cross
