Just looking idly at current kit and wondering why most of the road bikes seem to come specced with wide range triple chainsets these days? No use to a racer or even a fast roadie...

I have a triple on my roadie - hasn't caused me much pain - in fact it's helped out on some really steep stuff around Cornwall and Bath......I try not to use it though, I see it as a sign of failure hehe

I have to say I was a very early adopter back in '96 when I had my bike made up with a Campag Avanti triple groupset (52/42/32 with a 13-23 cassette). The thinking was that I cycled a lot up in the Pennines it seemed sensible, however I found that I prefered the 52/39 combo I had on the older bike, dropping to the tiny ring was just to much and if going up a steep hill I'd hardly have enough speed to keep upright. I see another trend now is the compact chainsets 50/34 type affairs which I'm not entirely convinced about either, and prob no use to me now that I live in the Fens! Still as I haven't sat on a bike for years I'll shut up wink

Cheers,
Rob

I had a triple on my last bike - if you need the low ratios then it's less of a compromise than a compact, to my mind.

Well I have a triple on my roadbike - but then I live at 1500 metres in the Swiss Alps laugh

Many, many times have I been glad of that inner ring, so in answer to your question I suppose it depends on where you use your bike.

I have triple Campags on my "road" and Audax bikes. With a 10-speed set up, they work perfectly and "does what it says on the tin".

Because the main market for most bikes at the price range you are looking at doesn't include the seriously good roadies who don't need them.

Everyone else does, or a compact, because you will become unstuck in the hills or mountains without one.

I am not strong enough to get round a major alpine or hilly UK route without a compact, and I think that is the same for 95% of people.

First bike or new to the sport = compact or triple. Or else you will suffer like a dog.

Was going to post the same response.

The majority of the market would be pushing for easier, more comfortable road bikes to ride to work/ on the weekend.

Those who race or at least compete at lower levels will ime build to their requirements.

what about compacts? they would suffice would they not?
Apparently Pinarello bolted a compact chainset to one of his pros back in the day and he won due having a wider gearing than anybody else on the hills and flats. I tend to stay away from triples due to the wide Q-factor and weight.

Sorry, slightly off topic, but what is a the biggest, practical chain ring on a road bike? i.e. what do the tour guys use?

53. They sometimes use a 54/55/56 for Time Trials.

Q factor for triples is no different to doubles. The inside ring sits closer in and the chain line is virtually the same.

So have hills become hillier since I last rode seriously then? Don't remember being defeated by much at all on 39/19 in this country. Also, I don't remember stating I was looking at any particular price point...

I run 39/52 on the front of my ribble road bike, as i'm getting older and lardier the thought of something even lower geared is very appealling .. I can see a triple going on the front before the end of the summer ..

No the hills havent got any bigger than when you last rode them , seriously (they haven't).

No you didnt state a paticular price point but look beyond &1500 in any catalouge and you'll be able (in most cases)spec triple or double depending on what you prefer so i presumed you were looking at the trek and spesh at 700 mark?

Other than that i think the point still stands people who want to have a bit of fun and get some exercise biet on a morning commute or weekend ride would feel more comfortable with their triple than a double and most likely only wanting to spend between 500 - 800 notes?

It's just offering choice to the consumer - I'm pretty sure any bike shop worth buying from will let you spec double or triple as you prefer. Not something worth getting worked up about really. :shrug:

39/19? I think you may be a little more able than the average. I had, and needed, a triple plus a 12-27 cassette for my first Ironman, and that was in Dorset, not the Peak District.

IMHO, any gear higher than 53x14 is a waste of a sprocket on anything other than a racing machine.
