Best bike shops for Campag servicing in Joburg?

You shouldn't be crossing your chain like that

 

Complete bullspit. If you have 22 gears, you should be able to use all 22.

You shouldn't be crossing your chain like that. Use the smaller gears at the back when in the large ring and the larger gears when in the small ring. You should still have access to all your ratios.

 

I've never had a problem with crossing the chain ... I go up and down like a yo-yo (both me and my gears). Ease up as you pedal and a Campy clicks across like magic.

C'mon TNT, you should know better than dishing out dodgy advice. The fact that it works doesn't make it good practise. By cross-chaining you are rubbing the chain, on the exit at the rear sprocket and enter at the front sprocket, on the sprocket sides. The fact that this happens under tension does three bad things. 1) It makes a noise. 2) It wears the sprockets, especially chainrings which are soft, on the side, which makes them thinner and more likely to then get pressure dents on the pressure face. 3) It prematurely wears the chain as well, since it's contact points are now not in line anymore and one side takes all the strain. The fact that modern bikes work in the cross chain position doesn't mean we should routinely ride there. Obviously if you don't care about equipment longevity, be my guest, but the rest of us will do the sensible thing. Edited April 16, 2012 by Johan Bornman

I also believe that.

I have 20 gears I want to be able to use 20 gears but there are a few bike shops who disagree.

 

That's why I set my own gears !!!!

[TNT1]

Why on earth would groupset manufacturers be spending billions on dev to give us more gears if we can't use them?

Just because you can, doesn't mean you should due to all the reasons JB kindly stated above. There is still an overlap of ratios even if you endeavour to keep your chain as straight as possible. But don't worry, the bike shops will love your repeat business to replace worn drivechains. Edited April 16, 2012 by slick

Right, slick and JB, post a pic of where it says you must not run the chain on the big ring and the lowest ration sprocket at the rear in the Campag manual?

[Cyclewizz]

From what I understand SANDRO wants to be able to use all 20 / 22 gears but from what JB says he wont be able to.

And tomorrow Sandro is taking his bike to JB.

Why would Campag care if you crossed your chain?

 

Does your car manual tell you that you shouldn't drag the clutch when letting it in?

[Sandro]

I hear what you guys are saying about cross- chaining but the fact that I shouldn't be using these gears doesn't mean I shouldn't be able to select them. No? That's all that I want, for all the gears to be accessible, whether or not I use them. Chorus is hardly Shimano Sora at the end of the day.

Don't be obtuse. That's an operator error you describe.

 

What is actually under debate here, is that, to use your analogy, the car maker made the car with 6 forward gears, and some pseudo engineer tells you that you can only use 5 of them. Cause y'all know better than those who developed the damn thing.

Try north cliff cycles. Alex knows his stuff eapecially on campy.

Well crossing your chain is also an operator error. There are plenty of bike tech related websites that will tell you why. Today's search brought up many of them. I didn't see any which tried to prove that it is good for your geartrain.

 

I have also clearly stated that all ratios between highest and lowest are available without crossing the chain. Another reason why your 6 forward gear analogy doesn't apply because on a road bike you have two gear levers with which to select a combination of ratios. Unfortunately you are probably too obtuse yourself to calculate how many overlapping ratios there are if you were to use the all the ratios in the small and large chainrings...

No. To use your analogy, it is OK to select any gear and drive the car as long as you like in that gear. Try that with first gear for 30kms tomorrow and report back to us.

No, that's not what I said. Read again.

I said you SHOULD not.

Because effectively you do have more gears if you eliminate the cross chain ones...

 

I.e a 9 speed drop high/low cross and you have 7

I.e a 10 speed drop high/low cross and you have 8

I.e a 11 speed drop high/low cross and you have 9

 

Or am I being stupid or missing something....

 

And by the way, I just checked my car manual, nowhere does it say I should not be driving in reverse gear all day long....I wonder why they dont spend billions in giving me extra reverse gears???
