Groupset selections

[Will1985]

I think he said selecting the right cassette would allow nearly as much choice on a double as with a treble.

This is half true. The triple will give you a massive range with nice jumps in the gearing while a double or compact can just about achieve the same gearing at the cost of massive jumps between gears*.

Almost the same gear range can be achieved with a 30/39/52 plus 12-23 as a compact 34/50 plus 12-27.

In practice, you might not need the bottom gears at all so I would suggest a double/compact chainset, then get a wider spaced cassette for any hilly bits and a close range (12-23) for flatter riding.


*Any setup could give you some duplicate gears, but generally more on a triple than a double.

Again thanks

Clearly there's more to this subject than I thought.

I guess if i analyse my cycling then I should be able to come up with a requirement. I suppose at one extreme you have setup for steep hills and the other flat roads.

My current commute is nearly all spent on the middle cog of the front set with occasional drifts onto the big cog. I rarely need the small cog in SW London.

thanks again

Why do you want a silly gear indicator - a quick glance down works just as well. And to be honest, you really do not need to look - just feel what you legs are doing.

I find that it is nice on hills to know how many gears you have left, so you can decide whether you can keep sat down and spin or you need to get up and grind because you are in your last gear.

I ride a triple of 30/42/52 with a 12-25 cassette on the back. When I first started out I needed the 30 for only the biggest hills I went up. Now I Never need to go lower than my 42-25. So what I am trying to say is that it dpends on your fitness as well as your terrain.

Young un, you shouldn't be on 42 x 25. It will be 30 x 18.

Sort out your combinations. Any experienced cyclist following you who notices you are using 42 x 25 will think you're a clutz.

 

[Young Un]

Whats wrong with using 42-25 it would be what I would use on a double if I had one.

Steve

 

[jimboalee]

OK, look a clutz.

 

[Young Un]

I don't look like a clutz - I dont like using the granny as I find it just too spinny and using the 42 ring it lets me build up my fitness. I am considering in the new year taking the 30 off like my mate at the club has done.

When you remove the 30 tooth, you might find you will need to put a couple of links in the chain.

A triple setup assumes the rider knows about gearing and has enough chain for the middle ring and the appropriate sprocket on the cassette to cater within the gear progression from low to high.
Using your ideas, the mech springs will be taken more than their designed deflection. ie the cage will be pulled more.

Also bad, but to a lesser extent, the chain has greater sideways deflection from the middle chainring to the extremity sprocket.

Running the chain from middle ring to largest sprocket might work, but It is not good form when you have a 30 tooth ring.
If you use your gears as they are intended to be, by the designer, it shows you know a thing or two.

You will remember what I have said the next time you are climbing Abberley or riding up to The Kettle Sings.

 

[Young Un]

Yes I would need it for really really big hills - but what I am saying is that for my current riding I don't need to use the granny ring.

[skwerl]

I agree.

If you're prepared to spend that much over the odds for a name, you may as well go the whole hog.

you see a few comments like these but no one ever seems to have any hard evidence to suggest Condor are over-priced.
given their location they're going to be towards the expensive end of the spectrum but I think they're competitive. Wouldn't have been in business for 60 years if they weren't

 

[De Sisti]

Campag ..... 10s will be phased out of the range in 2010/11,

When was this made official? I'm beginning to worry now. maander

Thanks guys.

Perhaps I should have checked first as there are already threads titled campo vs shamino.

The subject seems to bring out all sham vs campo purists. I'm actually not that bothered about being able to upgrade. I'd more likely buy a different type of bike than upgrade the components, but comes having had a good year on a trek based Tiagra.

One thing that still puzzles me is the double vs triple debate. I thought it was a simple as having two or three cogs on the front. Oh no, you can get different types of cassette giving different options.

The guy in the Condor shop produced a calculator to explain it all, but i quickly got lost.

I think he said selecting the right cassette would allow nearly as much choice on a double as with a treble. I'm not exactly expecting to take the bike up mountains so perhaps i don't need the 'granny' cog.

The current veloce seems to have a huge range of options.

Any advice about how to choose?

I am not a purist, and had experience of using Compagnola. But took the advice of the bike shop I went to to fit Veloce shifters and I am very happy with them.

Unless you are planning to race or go in for sportives, I would recommend you get a triple chainring as it allows you to have a much bigger range of gears. If you are going up any sort of hill you'll be grateful for a low gear - similarly if you have to ride long distances into a stiff head wind.

Following good advice I got here, I fitted a compact 12-27 rear casette on my bike. This means you don't get big jumps when moving between gears. I would recommend you get something similar.

I don't know whether it's just me Jimbo, but you don't half seem to write some pompous tosh sometimes...
