i have run both 60/70 profile in the last 2 years...and imho it makes no difference at all...................

as ali points out...there are arguments for both..!.......as for riding of the edge of the tyre.........................LMAO

In theory its contact patch - in reality its mental!!!

Can we go race yet ????

Well all ye non-believers ... when I ran the 60 profile, the tyre was worn all the way to the edge and the I slid the front more easily than on the 70.

When I used the 70 I've never gotten to the edge, there's always been a few mm left, and the tyre has only slid when the tyre was worn.

That was my experience FWIW

Bearing in mind that sliding the front is not necessarily just a result of speed, it can also be a result of how you're riding the bike.

Just my opinion :)

weird innit..i have never had a front slide other than in the wet.?...how come you have and i have not.?

Talk about a 'how long is a piece of string' type question!

Bike geometry, body position all effect how much load is on the front. At as much lean as we carry on these things the 70 has a bigger contact patch and the 60 has less, so if you're already on the edge where the 60 offers you less grip it stands to reason that you can slide it easier.

Phill you're lighter than me, a smoother rider and therefore you could be running your bike with less ride height, different fork internals etc ... lots of reasons why I get slides and you don't.

The list is endless :)

Less ride height??? You can walk under Fil's yellow 583...

Now mine & Chris Woods, you need a feeler gauge..

I don't bloody know what geometry Phill runs! :lol: The point is that seeing the different styles of riding between Phill and I and our weight differences etc would definitely mean we'd like our setups different.

At the end of the day, it would be impossible to know exactly what is going on with someone's bike without running some sort of telemetry and logging. You can guess all day long and riders can only go from what they feel.

Every rider and every bike is different and both have a big impact.

IMO.

I find the 70 doesn't give me enough grip on the grass, rumble strips and track overbanding hence occasionally losing the front, back and sides of the bike...

Should I try the 60 next season?

I think you should try MT60's - we'll get you special dispensation on safety grounds :D

Sorry Tony, wasnt on a wind-up... just humorous.. :)
