Recommend a cassette for my Ultegra set up?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Recommend a cassette for my Ultegra set up?

Here's my set up.

Crank: R700 compact 50-34 (10 sp, obviously)
FD: Shimano Ultegra 6700
RD: Shimano Ultegra 6700
Brakes: Ultegra 6600
Shifters: Dura Ace bar end (the 7800 series, not the cooler new ones, the SL-BS79)
Chain: KMC 10.93
Brake levers: I dunno, Tektro's?
Cassette: !?!?!

Was thinking about a SRAM 1070 11-28 cassette...

But only because I have one lying around.

Cheers

SRAM will work. I have it and like it very much.

1) Determine budget
2) Determine gear ratio
3) Find matching SRAM or Shimano cassette

Nobody can really help you with any of those steps. It's all personal preference. Or am I missing some wrinkle?

Budget? Somewhere between my wife's preferred budget of ZERO dollars ("you have 4 bikes, can't you move this 'cassette' thing around from bike to bike?" and my preferred budget of one thousand dollars for a ____ium custom rear cassette.

Gear ratio? Doesn't matter that much. It's for a folding road bike (Airnimal). Can't see doing too many big ascents on it, to be honest. I should be strong enough for what I'll encounter on it. Something general, all-around with a 27 or 28 for the odd big hill should suffice.

I was just vaguely worried about compatibility.

Thanks

Hmmm. The symmetry of having mostly Ultegra appeals to me... Good, I'll consider it some more.

Thanks

I was wondering about it with the 6700 stuff. But you're happy with it? Okie dokie, sounds good.

Sounds like you should use the SRAM you have.

Honestly,
Its ShimaNO so it you'll be replacing it next week and therefore why does it matter?
Just say'n

Buy Campgnolo gruppos. Stay away from that off brand stuff like Shimano. You'll only have problems.

I would love to! But it's like Mac (I mean Campy is like Mac) ... you start with PCs and then you stick with them, persistently and foolishly.

I'm even afraid of trying Campy for fear of falling into the abyss. (I did get SRAM Force, though, but that was a fluke -- someone practically gifted me a used gruppo.)

The term "gruppo" is to be used exclusively for Campagnolo parts sets only.

Not sure what you're looking for here. I run both Shimano and SRAM cassettes and find both perform well. If you don't regularly need 34x28, then I'd put in a vote for 11-26 as my favourite hilly terrain cassette. The 21-23-26 progression is tight enough to not cause me to fark up my cadence too much, and I've gotten up some absolutely ridiculous grades with a 34x26.

Actually what you wrote is what I'm looking for. That helped. 11-26 is good. So it's between that and 11-28 (which at least I've got).

Cheers!

Okay then, is there any reason why I should have the 6700 cassette as opposed to any other Shimano ten speed cassette?

Bizarre -- there's a 16-27 cassette! (Ultegra 6600 16-27T, to be exact). Just noticed this while looking around Ebay. Never knew that ... because it's not one I'd ever want, but okay, cool

11-26 is SRAM only. 11-25 would be 6700.

I'm guessing you have considered this, but I know a lot (all?) folders have less than 700c wheels. That will lower your over all gear ratio, correct?

Um, well, it's a 24" wheelset Airnimal racing folding bike.

As it happens, I have NOT done the calculations. What the *$)#*^! do you think you're here for?

In other words, tell me what this means for the gearing, please.

That's as good as reason as any.

(Is it me, or does these kind of symmetry things start to matter? Never thought they would, but lately I've been trying to get my seatposts and stems to match, or my bars and stems, on various bikes. Crazy or what...)

I think you would want a standard crank and an 11t cog with those 24" wheels. You are going to run out of gear otherwise

this means that a 27 with those wheels will feel like about at 30T cassette.
you could probably get away with a 11-23 if you find it on closeout.

what this really means, is that the gear ratios determine how many times the wheel goes around for each time you pedal. your wheels happen to be smaller, so one time around for them doesn't get you as far as on a 700c bike. therefore it's easier to pedal for a given set of gears

Well, good thing I've got a compact crank on this thing, rather than a triple. Sheesh.

Anyhow, thanks for dumbing it down for me. I will look for something like an 11-23.
