I remember reading here that there was a certain size inner tube that can be used in the front or rear, albeit for a short distance, when in an emergency. Can't remember if that is valid for the X & the R, and I can't for the life of me find the fapping thread!

Preparing for a trip now, I've got a spare Metzeler, which was used in the rear, with the following text on the tyre...

4.50, 5.10, 130/70, 120/80, 130/80, 110/90, 120/90 - 17

Also, ME-F17M/C(B)

Can this be used for front & rear, if not, what size inner tyre can be used for both on an XTX?

Cheers peeps

A front inner tube (21") can be used in the rear as a 'get me out of trouble' option, but not the other way round.

I've got the X version, both rims are 17" (120/70 front, 160/60 rear). Would it be ok to use the spare tyre mentioned above in front & rear?

Thanks

It would be ok, but it is a nonesense to carry a 21" tube on abike with both wheels being 17".

Get a tube for the front wheel (17" 120/70), you could use it on the rear wheel too.

have fun,

Cheers dude. I think you missed my first post though, I do have a 17incher, I just don't know if it will work on the front as well as the back

a 17" front tube will work at the 17" rear wheel, but not the way around. in short, carry a 17" front tube.
