I have decided to go -1 on the front rather than +3 on the back
So i plan a 15t 525 Renthal front
a 41 supersprox rear
but the chain is what i'm wondering about i want a decent chain and have found you can get a D.I.D 525 VXGB - 106 Gold which is being sold as an upgrade but you can also get a D.I.D 525 ZVMX -106 Gold which from the same company which claim it to be an extreme upgrade.
The VXGB =£73.90
The ZVMX =£106.90
The difference of £33 would pay for the chain tool to replace the chain myself, Has anyone had experiance with either of this two chains and is the extra upgrade one worth the extra. I don't rack up huge milage and i don't tend to ride like i'm riding the TT but i do like a good "wind" on now and again

I wonder about other chain brands, like EK who claim to be better than most but is that just sale patter or is there a particular brand that are better than others.
Sorry, starting to waffle on a bit now.
