The directional arrows on a rear bonty xr 29er tyre are the opposite way around to the 26er version.IE tread faces different ways for each size. Noticed my mates tread the other day and laughed pointing and mocking until he shows me the arrows. Would it be to do with better rolling resistance for the 29er and better braking for the 26er. That's what I told him any way like I knew all along.

It's to confuse the users of the smaller/less niche wheel. 😆

And no doubt to slow them down even further eh stu.

Yet another way of making/pretending to make stuff more optimised/use specific.

It already is specific to rear and 29" wheels so its not that.

And to start an argument on a geek based website.

Guilty but still curious. And not Bi curious before anyone starts on that one again. Just happened to comment on that american tranny program and all hell brakes loose.
