Shimano Ultegra 6700 10 Speed Cassette, size?
Postby mirz » Sun Nov 25, 2012 2:05 pm
but checking on my bike, all i can see its Shimano Ultegra 6700 10 Speed, it does not mention wether its 12-25 or 11-28.
only from Giant's website i can see that current cassette is 12-25. is there a way to findout this? thanks.

Hi There,TimW wrote:count the teeth on the big cog, if it equals 25, then it is a 25. Count the teeth on the small cog, and if it is a 12 it will have 12 teeth.Tim
I hear a lot that, the more teeth, the better/easier it is for climbing hills. But how bout with less teeth? Would it translate to faster speed on flat road?
Thanks!

So yes it'll be a lot easier for you but if you can stick it out then do so...

I actually found going from 12-27 to 12-23 was one of the best changes I ever made with my compact crank. You will naturally be forced to start building muscle, getting out of the saddle, by losing those big gears. Thing is, if you're like me, then slow twitch is your friend and getting a smoother cadence and some more power is going to help you a lot more than a big cassette. The perfect cassette IMO is the 11-21 DuraAce 10 spd. You want all the gears to be close, because that makes your spinning much easier. Dropping 2 gears from 21-27 is like changing cranks. It's a big change, and it won't make your spin easier to maintain - you'll actually just end up having to start from scratch and build your rhythm again.
Those super nasty hills you wanted the 28 for - don't push so hard on the flats next time, and stay in the 21 sprocket. You'll be surprised how little you REALLY need that gear. A lot of climbing is psychological... the climb I was testing these theories with was a 200m climb after a 500m of gradual increasing gradient. It was always the hill I bork on and find the lowest gears, about 16km into my ride home. On Friday afternoon, with 200km in the legs, it gets tough! Anyways, I actually have a climb that isn't that different about 2 minutes after that climb, after a long downhill run. It's almost as steep, but I have a fresher pair of legs after the descent and a lot more speed is carried towards the climb. I don't normally think about it, I think about the 50kmh I am going to try and maintain on the gentle descent on the other side. Unless you physically cannot climb those hills, and you are spending a LOT of time in the smallest gears on the cassette, your overall benefit will probably not exist. Smooth spins and easy transitions between gears will make your rides easier than a 28 sprocket.
In summary, HTFU.

I don't disagree that you can get away with 23 tooth on gradients up to, maybe, 10%. I suspect the average rider will be standing up and grinding with 23t at 10%.Xplora wrote: Those super nasty hills you wanted the 28 for - don't push so hard on the flats next time, and stay in the 21 sprocket.

This isn't intended to be a brag, but as a rider who regularly challenges himself with 15-20% avg. grade climbs, a 28 tooth is indispensable. When I'm doing 20%, might get a hundred meters sitting down, but it really is a stand up and grind affair down on the 28. I literally cannot imagine doing that sort of stuff on 23.

If you're putting in massive efforts to climb with a 28 and bonk halfway up the hill anyway, then you need it. But I think you should only get the cassette you NEED. Mirz is new, they need to start climbing in the big ring and walking up the climbs when they reach exhaustion, rather than buying bigger cassettes.

I guess we are saying the same thing, but we have two different experiences. For me, for the terrain that I enjoy riding, I wouldn't give up my 28 for much. For you, a much smaller/closer cassette will do.
I do think that encouraging a new rider to give up a few gears is a surefire way to bum them out when they can't make it up a climb. Or when their knees are so sore that they throw the towel in.
My thoughts on the question from the OP would be: sure, work out what cassette you have. However, spend a few months riding it (at least), then work out the weaknesses of your current setup, then make a decision on whether more or less teeth would be beneficial to the terrain that you enjoy riding.
I would also suggest that, the early stages of riding should be about building base, not grinding up hills in bigger than required gears to build power. Just my opinion on that and I'm sure there are other opinions out there.

I'd like to know where the 200 metre climb is between seven Hills and parramatta i assume that is distance not verticalXplora wrote:. the climb I was testing these theories with was a 200m climb after a 500m of gradual increasing gradient.
or was it on the Trek Sat ride,Freemans reach? blue mountains?

Xplora hasn't mentioned gradients or elevation specifically in any of his posts so I assumed he meant it was a 700m long climb of unknown ascent or gradient, first 500m fairly easy and the last 200m ratcheting up.TimW wrote:I'd like to know where the 200 metre climb is between seven Hills and parramatta i assume that is distance not verticalXplora wrote:. the climb I was testing these theories with was a 200m climb after a 500m of gradual increasing gradient.

Without knowing the grades or elevation it is hard to comment on whether its a sprinting climb (avg grade 2-5%), something a little harder (avg 5-8%) or a bit of a grind (8%+). Not that it matters to the OP.

It's exactly as jim says. The thing is, it really is all perspective. One man's Mount Doom is another's Hobbiton. It's a mongrel hill that is really hard for me to punish unlike much of my commute. I'm not sprinting it.jimboss wrote:

My guess is that the OP needs to focus on dominating these hills more.

It's a general rule with few exceptions. Just about all the literature on hill climbing suggests high cadence is better than mashing.TDC wrote:Better for you or better for everybody?biker jk wrote: When climbing, high cadence (of 90 rpm or above) is better.
Here's but one example.

I have to respectfully disgree. I think that the most effective cadence differs from rider to rider, a lot of it depending on their physiology amongst other things.biker jk wrote:It's a general rule with few exceptions.

Here is some 'literature' (with references!) that supports my point of view.

A big part of the problem is the Harden that occurs on the rest of the commute, followed by the Up. I do look forward to upgrading the crank to a standard and keeping the 12-23 onboard, that's surely enoughTimW wrote:Go on be a devilXplora wrote:I will humiliate myself by divulging the location of said road...TimW wrote:which Hill/Road is it??

I have started training today, doing some sprints and suchlike on the ride home to try and make the magic happen.TimW wrote:Spill the beans!!!!!!!the road son tell em the road!!!!
I went up that hill I was talking about in 50/19, maybe 50/18. Just grind grind grind. I think it really was psychological. I also made sure I was not busting my cafoofle leading up to it.
Anyways... Xplora 1, Hill 0.

In front big has 53 teeth.
Totally agree with people here that power is all in legs, but for a biggener like me uphill is a struggle and won't like to avoid hills with experienced mates just because of this. I'm confident that with practicing over a next year or so I would improve.
It's more like a half way solution I was checking out.
Wiggle is apperntly selling this cassette for under $60.
Is this any easy DIY or should be done by LBS?
