Inner tube

[davidll]

Hello

Grateful for ŷour help

I am wanting to replace an inner tube for a mountain bike tyre but can’t work out what the “f” and “025” means in F 26 025.

Any advice appreciated.
Thanks
David

I have no idea but it probably means nothing of any importance.

Buy a tube to fit the tyre.

E. G. If its a 26" tyre in 2.0 width, search for a 26" tube - width 2.0.

“F” is for front

Be careful with tubes and sizing.

Look on the tyre for the ertro code.

Say 42x559 this is more important than knowing it is say 26"
