It's fairly easy to over tighten bolts especially with carbon parts which can cause (expensive) damage. I'd recommend you get one and not take the risk. Won't break the bank and will be useful for future maintenance [emoji106]
To be honest its not something I focus on. I guess it just comes as a result of keeping up the momentum? I just try to go as quick as i can and put out as much power as my tired legs will let me [emoji21]
Ah. Horsebridge Hill. Only ever climbed it and taken the descent into Fittleworth. I can imagine the descent being interesting in those conditions [emoji6]...
Conti 4 Season: 28's at 75psi on my Winter. Feel great in the wet and very comfortable. Conti GP 4000S 2: 25's on my summer at 90psi, love them. Like the look of the Pirelli's mind you...
