19"x4.00 front and back

[Guest]

hi guys, greetings! am new to this community and has lots of questions ...

I have a 1978 GS550, I am planing to swop both front and rear to 19", I know that is not the most practical decision to make but I had already bought my tires, so no turning back ...

So as you would have expected, now I have problem looking for rims, I wanted a pair of H type high shoulder rims, with 19 x 2.15 front and back.

There are motorcross rims that is 19 x 2.15 x 36 spokes, but does that means they will fit my GS550 stock hub without a problem? what should I check before I make my purchase?

here's a picture of my humble bike ...



Thanks!

nice looking bike especially the paint. Where are you located?

If the spoke count is the same, I "think" all that will need to change will be the spoke length and nipples.

Curious about how this will end up looking, can you keep us posted?

And welcome to the forum!

Mike's XS has decent prices on rims and spokes, although I'm not sure if the spokes will be the right length for use with a GS hub. http://www.mikesxs.net/products-56.html#products
At the end of the day, you are talking about a lot of expense ($350 minimum) for a fairly minor change. You sure it's worth it?

hi mr. posplayr, nice to meet you! and thank you for the good words! I am from Malaysia, what about you? that was the picture of the bike when i first got it, it is undergoing quite a drastic modification though, here's a sketch for my plan.

Thank you musicman for the warm welcome!

Regarding the fitment of spokes, I thought as long as the spoke count is the same, the rim will be able to fit the hub. But someone told me the angles of the spoke holes on the rim can be different ... which is something I need to find out.

The person told me the angles needed are as follow:
C°, D°, E°, and F° ... which I couldn't find out because I'm not quite sure how to do it ... can anybody help? =)


but then again i am not sure ... if any 36 spoke wheels can fit 36 spoke hub, then i'll just get any...

And for sure buddy i'll keep the post updated, still lots of work to be done! =)

Hey Nessim, thanks so much for the infos! really appreciate it! yeah I found Mike's XS too, I wanted a H type rims so I found him, decent price indeed! but then again i'm not sure if it will fit GS550 stock hubs?

Also, question about spokes, are the spokes all universal with a buffer length or i'll have to get very specific spokes?

it's really tough ... I wish they would had made things simpler ... why can't they standardize these technical details?
