I decided that 120mm of travel was about right for basically the same terrain, it seems a fairly common choice.
my XC bike is 100mm either end, great for all but the biggest stuff. It climbs and rides all day so well! The thing is as you start going up in travel unless your forking out a lot of money the climbing and pedalling is really going to be effected and make your day hard. However it will probably descend like a dream, but then why not get downhill bike… And also if you have more travel on your bike, unless your really hammering it then you will become a lazy rider.
e. I’ve got a FOX Float RP23 on the rear and it’s OK, it’s the first and only rear sus’ I’ve had so I can’t compare it much. I like the propedal on the Fox, set to firm it’s OK and any other setting it drains me even on the road on a mild gradient although I’ve had a cold and been below form slightly.
I’ve had an RP23 for many years now, great! I have a little pro-pedal on, run with a little more air than your supposed to for my weight. But depending on the frame design you may need more pro-pedal to get it pedalling well.
And I’ve got 180mm discs which seemed to be the common advice.
It’ll be interesting to see how that works in Welsh forests over the next couple of weeks.
I’ve just equipped my XC bike with 2.3inch tyres, a 203mm rotor up front and 185mm rotor on the rear ready for Chamonix descents this summer. I had previously ran 160ish mm rotors front and back with no problem except on the very biggest descents. So around 7inch rotor wise is a good call.
I’ve just had 2 days in Snowdonia riding with a good friend. Top stuff! And today I called in at an old haunt near Shrewsbury for miles of lovely singletrack!
I think you need/want a full sus David. Medium size tyres, medium size rotors, short-mid travel and you’ll have a blast!
