why do most roadbikes...?

[bigguy]

Why do most roadbikes not have a triple chainset.. eg. a granny ring! Surely it would be an advantage to have it,....... where i live, close to the antrim plateau ( mountains) there are some damned steep roads! my opinion would be that it would be a necessity to have!

triples are gay

at least that's the theory I think

I thought loads have triples?

I think a proper road bike is expecting to be ridden on reasonably level roads quickly and all excess weight is dumped

Horses for courses, I suppose.

Whether you need a triple will depend on your fitness. In addition, the compact chainset has reduced the differential between the traditional double and the triple. You can now ride a double, but have similar ratios to a triple. If you spent a lot of money shaving weight off your bike, you are not going to put a 3rd ring on it when you might only use it once every so often. Personally, I prefer a double.

i have a giant scr2 and that has a triple - as does the scr3 i think - but the giant range has changed for 2009 so not sure on these models

>triples

= MTB

Double = Roady bike

:On the training set of wheels I've a 13-25 (which is a touch TOO big) 1.

On the Racey Wheels 2. - I've 12-21 block 9sp. ~ both.

On the C.Set side I've a 42 - 53 ring set-up.

On 1. i could do with a biggest cog of 23 but that'd mean having a 12t which i dont want as its TOO low for training on.

Shimano should bring out a 13-23 including an 18t.

Blimey this website read my mind

There remain a number of cyclists that believe tradition is more important than progress, and since early, classic road bikes didn’t have triples 30 years ago, they still shouldn’t now. This is frequently the same type of person who feels that "steel is real" (meaning that any other material, be it aluminum, titanium or carbon-fiber, just isn’t what a bicycle is supposed to be made out of) and probably doesn’t wear a helmet.

>triples = MTB Double = Roady bike

Triples = OK knees

Doubles = fukked knees

Your a 'roadied' MTB'er !

Sacrilege - from an MTB'er p.o.v. !

 

[Smokin Joe]

Doubles = fukked knees

Utter rubbish.

 

[Dayvo]

Utter rubbish.

If you say so!

 

[Scoosh]

If -

Triples = OK knees

Doubles = fukked knees

Compact = ???

I thought that was the whole point of a Compact - certainly according to the ChainReaction link.

Its not fukked knees thats my prob on the hills..... its just TOTALLY fukked!!!..... LOL
