Xtx 660
 

Hi All
Heading to Argentina next October with an XTX whick i bought because of low milage and lack of knowledge my problem is the 17" wheels, front forks look like they will take 21" no problem but back 17" look tight not sure what tyres i will need for Argentina to Texas, I would be greatful for any help or solutions you can offer.
Cheers
Simon

Depends on you skill level. It's usually more a case of what size you can get. 21 and 18" are more common. Even in Chile and Argentina it's not a case of finding your favourite tyres in every bike shop.
