Morning

I currently have an 11-28 cassette and would like to go to a 12-30 to give me some extra help when climbing.

Is it worth it and will it really help?

Thanks in advance

    If you already have a compact (34-50) chainset on the front and you struggle with steep hills in an 11-28 then it might be worth looking a 12-30. You might need to get a medium cage rear derailleur that can handle that cassette though.

    If you have Shimano, the cheapest way to find out is to buy a Tiagra CS-4600 12-30T cassette and give it a try. You will need to wind the B tension screw in to achieve the required clearance between the 30T cog and the derailleur top guide pulley. Chain length will be ok as long as you don't use the 50T-30T cross chain combination.

    Alps fine..FWC... depends on your climbing ability. Two different types of climbing, Alps are long slogs around your threshold.. The Lakes... well be prepared to have your legs ripped off... better too many gears than too few!

    As long as you don't mind the expense then it can't do any harm. I did the Fred with 13-29. I flew up Honister but realised then I'd be walking up Hardknott. The extra two teeth probably won't save you from walking if you would have on 28 but if will make it that bit easier if you can keep riding. I'd practice climbing in high gears to get used to low cadence. As I walked up (only cost me 7 minutes in total) I was overtaken slowly by folk on standard cranksets and not very large cassettes pedalling very low cadences.

    I also found the 29 very useful in the Alps.

    True - but why put yourself in that situation? It's not as though putting a longer chain on effectively costs you anything.

    Need to post what groupset and derailleur (long or medium) to be sure. A long cage Shimano will normally take up to a 32. I plan to use 34/32 for the FWC (and lose a shed load of weight first).

    If you need to ask then I'd say do it. In fact, you might be tempted (as hinted above) to fit a 32 cassette even if it means a new RD (not necessarily expensive - especially if it helps you enjoy your day). I even stole a tooth up front and ran a 33 chainring (partly because I was limited to 30 at the rear)

    Go as high as you can - anyone that willy waves about their small cassette clearly has a small willy and walking sucks

    Can I ask, what make 33T chainring did you use and which chainset?

    I came in here prepared for the usual "I went up Hardkott on a 11-23 and thought it was too easy...."

    What a nice suprise.

    OP, get as many teeth as you can. If not for your legs, for your head.

    I went from a 11-28 to 12-30 last year and the extra two teeth were a godsend on gradients such as Crawleyside, Grindon Moor and The Stang. I'm not a bad climber, but when you're hitting 20%+ gradients, I can stay seated and spin, when others are out of the saddle coughing uo their lungs.

    Now that I've changed to 5800 105, I've taken the opportunity to fit a 12-32. I couldn't care less what other people think.
  • The one thing not said though is that Alps and Fred Whitton are quite different propositions from each other. I dont think the larger casette is as beneficial in the Alps as they are gnerally not as steep as Honister and Hardnott, just a lot longer with maybe a 7,8,9,10% gradient.

    True - but having gears in hand isn't a problem. The gradients tend to be pretty consistent so you just choose a gear and tend to stick in it.

  • I ride in the lakes a fair bit, you can get away with an 11/28 on most of the climbs but Hardknott and Wrynose are in a different league. My winter bike has an 11/32 and I find it much easier on the legs and I seem to climb at the same speed but less stress on the legs.

    If you are getting a medium cage RD you might as well get an 11-34.

    Neither, http://vintagecassettes.com/tdk/tdk_fil ... k_type.htm

    TDK SA was a "work-horse" of type II cassettes. It was the most successful TDK cassette ever. It offered oustanding performance for reasonable price - a deadly combination for the competitors. The formulation is based on Super Avilyn particle - the TDK answer to chrome based type II cassettes. It appreared first around 1974

    Shimano 105 equivalent. :D
