I'm thinking to buy the rims in EEUU to change my rims. I think that TL is better than TT...

Thx, Sergio

Properly installed tube type tires are still not as good as tubeless.  If you do need to change rims, I would highly recommend doing so at your earliest opportunity.  A puncture in a tube type often leads to a blow out while the same puncture in a tubeless tire will cause a slow leak.

The European rims are TT. The bike has also a different tiresize from the US models.

The tires are bigger in Europe.  The euro version should have 90/90 front and 4.25/85 rear. At least according to one conversion table, 4.25 is somewhere between 120 and 130. So I could choose between 120/90 and 130/80.  Back in 82, 4.25 was rather wide, so I fitted 130, and it presents the bike in a way that suits it well. Now I am riding tubed 100/90 Promaxx front and tubed 130/80 Pirelli rear - and it works well.

I do not know whether there are height/width differences between the EU and US models that might make the 130/80 a to close fit in US models. It could also be how the tires are shaped.

I am riding tubed, and do not worry at all.

I find the two rim by $35, but, the shipping to Spain are $133!!!! (about 38 Lbs)

I'm looking another way more cheaper...

With the tires:
- front 90/90??
- rear 120/80??

It's a good combination??

Thx, Sergio

120/80 rear is a little bit to small according to the registration papers (I assume that you have 4.25/85 listed). To get the same dimension, you should have 130/80 or 120/90, but I guess that no one would care if you were pulled over.

NO, I have 4.10-S18
