Can't judge what the other side would be like from memory, it's a long gradual incline I think, you'll get the panoramic views when you go over the peak but you'll be down through the vista part pretty quickly.

I'll make sure to take it slowly so that I take in the view...
Also, just one more quick question: if I am changing the cassette is it worth changing the chain too? Bicycle isn't that old (3 months by the time I go to Brecon) but I'll probably have done about 800-1000 miles on it by that point.

probably worth it, that's the sort of distance stretch will have begun.

Let's have this right for new members as we don't want them to think that we are a bunch of amateurs.
Chains don't stretch they wear and that wear increases the pitch length which is perceived as stretch.

You'll notice I used the word 'wear' ! #pedants #bikegeeks

Hi judahlow, I've done this route many times in both directions. me & my girlfriend often have a long weekend in a cottage in Peterchurch (courtesy of my girlfriends employers) & take the bikes with us. we go from peterchurch - hay on wye - capel y ffin - abergavenny - longtown - peterchurch. or the return loop. The hay - capel y ffin route has a fairly steep climb up onto the top of the beacons which certainly gets the lungs working but the route your taking is a longer, more gradual grind to the top. depending on your fitness the stock 25 tooth should be ok but as a bail out maybe stick on a 28 tooth. I think a 30 tooth is a bit overkill IMO. Whatever you decide to do though make sure you enjoy the journey, the scenery & views around those parts are absolutely spectacular. enjoy !

So I installed the new cassette and chain yesterday (both SRAMPG850) and it's running okay, but I keep getting what I think is chain rub on the back derailleur. It's certainly making a bit of noise anyway. What level of chain noise is 'normal'?
I've messed with the indexing a little to see if that fixes it but no luck (I might not have done it properly, admittedly). I did think it was rubbing on the rear derailleur cage but it would be by such a small amount that I can't really see it with my naked eye.
I also thought perhaps the lower jockey wheel is rubbing the largest sprocket when in smallest chainring as the new cassette is 28 tooth rather than the standard 25 tooth for a Triban 500se. I tightened the b-screw, but it's hard to tell whether that has made any real difference. Even worse, I now occasionally get a brief metallic 'ting' sound when shifting up gear on one or two of the sprockets.
Christ, this is exactly why I should not try to fix problems myself !!

Have you threaded the chain correctly and not got it running over the rear mech housing? Any chance of a little vid with the cranks, wheels, chain turning, done via getting the wheel propped up and said sound demonstrated, so we can assess what you're talking about? Prop the off side on something non abrasive, so you can hold the bars and spin the cranks perhaps (and / or get a helper involved to film a little clip)?
