Hi all
I'm planning on cycling in the Brecon Beacons for a few days/week in September and, as it's a rather hilly place and my first time doing something like this, I've decided to get a new cassette to help spin up those hills. I'm led to believe that a 11-28 will fit fine with no other changes needed, but what about a 12-30? Theoretically the latter is a bit of overkill anyway, and will be annoying when I come back down to lower levels, but I've managed to terrify myself that I will spend 50% of my time trudging up hills rather than cycling up them. From what little I've read (I'm a novice to bicycle mechanics) I might need a different rear dΓ©railleur to accommodate a 12-30? If so I'll probably stick with the 11-28 as I can't afford more than just a cassette on top of all the other stuff I need to buy.
For a bit more detail I was thinking either a Shimano Ultegra 6700 or a Shimano 105 5700 (I'd probably opt for the latter in the event of getting an 11-28 as it's cheaper).
Any help appreciated and sorry if derivations of this thread have been done endlessly.

Okay so I've just realised both of those are 10 speeds and the Triban 500se has a 9 speed? Any suggestions as to other decent cheap cassettes?
Something like the Shimano HG80 9 Speed Cassette perhaps?

Yeah I looked at that one but weirdly, as you point out, no 11-28. Will have to plump the extra tenner for a HG80 I guess. Just to confirm though, I can fit that onto my bike without messing with anything else? I'm also wondering how much difference an extra 3 teeth will make...

As it's 9 speed yes it will go straight on. It will make the climbing a little easier over a 25.

In that case then yes you need 8 Speed. Search 'SRAM PG850' on here, i think there's a lot of talk about them and people rate them.

The 500se with the blue hoods on the gear change levers is 8 speed rear cassette. The biggest sproket on the rear on the standard cassette is 25 teeth. I have changed mine on the Triban 300 (same gears) to an 11-28 Shimano HG50 which cost about 11 quid. It gives a good climbling range when useing the 30 teeth front chain ring. I did one of the climbs out of the top 100 climbs book (that is in Derbyshire) three times last Sunday using mainly the 30 x 24 (and the 28 for a very short steep part of the climb).
P.S. the rear mech (microshift) should be able to accomodate a max teeth of 32

Also, not sure about the 32 teeth as I looked on Microshift's website and it suggests 28 teeth is the biggest (see here: www.microshift.com.tw/RD-R32S_city_8s%20.html). Would love a 32 as I'm planning on cycling over Gospel's Pass in Brecon Beacons which is apparently the highest road in Wales...

I've done the Gospel Pass a couple of times, it has a few steep parts, a stretch at the base before it opens up and a couple of peaks when further up. One of the latter is intimidating, as it looms ahead far above you in a dramatic vista but actually it's not really acute and you're through it soon enough, just stay cool and take your time. You should be OK with a 30 / 28 ratio, the last time I did it, I was on a 34 / 28 lowest combination, only stood up for a few peaky bits.

Well I've only planned to cycle 20 odd miles that day (i.e. from Abergavenny to Hay-on-Wye) with a stop off in Llanthony to refuel and wander around the priory. I'm going to get some hill training in around Surrey in the next few weeks and hope that adding a pannier or two with some clothes and stuff in it doesn't make too huge a difference... Thanks for the information though!

You'll be OK, it's a 3 hour undulating terrain ride from here and I managed it, the first time I did it was on a 176km loop from the Severn Bridge, chasing an ex Team GB triathlete loony, on a cold day and headwinds home - eek .

Just realised you're doing it back to front - the way we do it is from Hay to Abergavenny; it's a dramatic mountain col style climb from Hay, with long ranging views on open moorland, a bit like the ones the TdF did in the Pyrenees this year. The other side is windy tight tree and hedge lined meandering lanes, set in a more enclosed typical Welsh valley.

Will be a nice long descent at least... Would have done it the other way around but I need to get back to the West Midlands afterwards so wouldn't make sense to go south.
