11-29 vs 12-29 SuperRecord Cassette

[3Pio]

In process of making lighter my C60, im thinking to upgrade my Chorus 11-29 cassette to SuperRecord, and have dilema 11-29 or 12-29.

Using short Cage Campy Record rear Deraileur (2015 ) and in front i have Campy Record 2015 semi compact crankset (52/36) (11 speed).


So what is the weight difference that i'll get from Chorus 11-29 to SuperRecord 11-29 or 12-29 cassette?

And which combination u prefer and why? 11-29 or 12-29?


Thanks

Don't ride Campy, but which gearing you want really depends on where you live. I prefer 12-25 with a 52 up front for flat or undulating terrain. When going to the mountains I like a 12-28. The 11 doesn't contribute much for me.
Sure, bombing down the alps its nice to have one extra gear on the top. And when doing criteriums with a tailwind I do get close to the 12. So, for racing on flat courses I might go for 11-25 or 11-23.
If you really worry about weight, the 12 or 11t is not where you make a difference.

12-29 cassette. Unless your name is Mark Cavendish, you are not going to turn over a 52x11 gear unless you are falling off a cliff. At 90 rpm, 52x11 equals 33.5 mph. 52x12 at 90 rpm equals 30.7 mph. How often do you ride 33.5 mph? A hill has to be very long and/or steep to get up to 33.5 mph. Actually, if you jumped off a cliff, you would not reach 33.5 mph before you went splat at the bottom. Unless the cliff is the Grand Canyon. I'd rather have one of the extra intermediate gears you get with 12-29 over 11-29. You will use that much more.

I definetly need 29 at the one end (climbing a lot) So that's why i choosing between 11-29 or 12-29.

if i go 11-29 im loosing 16T gear, if i go 12-29 i have 16T but loosing 11.

Which cassette would work better with short cage Campy Rear deraileiur and Semi Compact crankset?


@RussellS Thanks.. Seem that answer i was looking for

I use a 12-29 even with a 50/34 crankset. The 11 would get used so infrequently that I'd rather have the 16.

Personally, I would never pay $300+ for a Super Record cassette. That has to be one of the worst cost per gram areas to save weight. What do you save 60 grams for an extra $200-250? That is over $3/gram.

Same amount of money i need to pay if i like to shave those 60 gm in handlebar switching to carbo, and also loosing the stifness so i decided to keep the alloy one. And dont have idea where to shave the weight else (that why i opted for cassette)

Any ideas?

Colnago C60 Frameset + Colnago Carbon Seatpost

Campagnolo record groupset (except Chorus 11-29 casette)

Selle Italia SLR Carbonio Flow Saddle

Time Xpresso 10 Pedals

Fizik R1 110 Stem

Zipp Service Course SL-80 handlebar

In process of ordering Bora One 35 tubs + Vittoria Corsa G+

So where to shave weight?

[Kurets]

Both cassetes will work fine with your derailleur provided it can handle a 29t in the rear.
About never reaching 33mph or 53km/h I think people need to consider racing. It isn't common, but with a tailwind even amateurs will reach those speeds. In fact in a pan flat criterium I did this year, we topped out at 53km/h on the tailwind section on most of the laps.

11-29 is better than 12-29 for riding and for resale.

You are at the limit of where it's relatively cheap to lose weight. You have to ask yourself whether those 60 grams are worth $300 to you.

what AJS914 said.
I recently put a 12-29 Chorus ( was on a 12-27 Record) on my bike when i needed a new cassette. I decided not to spring for the Ti cogs to save money. Choosing an 11 cog over 12 to save weight is probably ridiculous, as the difference cannot be more than a couple of grams. You will probably infrequently use the 11 unless you are an elite rider, but you will often use the intermediate cog (and the narrower jump that you would otherwise lose). Losing a couple of grams is a poor reason to chose a cassette- chose on the basis of the utility of the number of teeth for your riding style and terrain.

And what beatnik said above really makes no sense- resale is irrelevant (I am assuming that you are keeping the bike, not selling it, and once the cassette is worn it will not add anything to resale value) and as far as better for riding- that depends on the rider.

I would go for 12-29. I don't think we really need 11, I race with 52x34 and 12-28, flat races, hilly races, granfondos, etc. and I can't feel any disadvantage with my 12-28.

As an example, Movistar riders use 12-29 in the 90% of their races, and they keep it for training. They decided in the team to use this combination for every day. It's true that they have a 53x39 crankset but they are pros hehe.

Unless you've got money to burn, I would never spend that kind of money on a consumable (ie something that wears a lot faster than other components).
A handlebar would me a much more economic upgrade if you see it in long term usage.

And if you really want a lighter cassette, why not consider the dura ace cassette? I ran a 11-32 5800 cassette on my 2015 chorus drivetrain this summer and it worked like a charm. Shifting was good and didn't have any hickups

If you care about downhill go for 11t if no 12t.

Take into account that those 53 km/h are calculated @90 rpm. On flats, I hope for you that you don't max at that rpm. 100 à 110 rpm is more realistic. And then, we talk around 60 km/h. More than enough for 99% of the situations. And frankly, having a 16t seems way more important than those 1% situations where you wish you had a 11T. FYI : I reached 67 km/h on a flat section with huge tailwind on 52*12 a few weeks ago.

[3Pio]

Since i climb a lot, seem that 16t is more important to me then to have 11t. So 12-29.

And just to make things clear.. Im not trying to shave weight between 11 or 12. Im trying to shave weight from my Chorus 11-29 going to SuperRecord. I asked about 11-29 or 12-29 just to choose correct gear ratio while im ordering the cassette.


Also i just bought this frame, and not planning to sell soon, so i dont worry that much about selling value (i'll anyway use this cassette untils it's for selling).

I checked Shimano Durace suggestion, but it's not big difference with campagnolo Super Record, specially considering that i'll need to change freehub on one wheelset (or both).

Im not sure about longevity Chorus vs SuperRecord cassette.. I guess based on experience now, i should get about 12000 km from Chorus cassette. Can i get the same km's with SuperRecord and if not what to expect ?
