Update
So a few changes recently.
1. Gone narrow/wide with a works 34t - looking forward to seeing how the 34t works for me.
2. ditched the cSixx full guide in favour of a home modified MRP G2, top guide only.
3. Mavic rear wheel gone in favour of a Syntace W35. Cannot believe the weight difference, when I was transferring I had the tyre and disc on and the syntace was still lighter than the stripped Mavic! So far, so good in riding. I'll see how it goes for a while before I do the front too.
4. Sugru chainstay protector. This stuff is amazing, no noise at all and it's put up with plenty of rides. So much better than the neoprene chain stay protector I had before.
5. Rock Razor gone. Great grip but too flimsy, high roller on in the interim whilst I decide what to fit.
