weight saving?

[young Ed]

so has any one actually weighed every thing involved in gears eg:derailers, cassette free hub or free wheel, etc etc
or just weighed bike before and after conversion
Cheers Ed
P.S Please help me in my argument against the other 4 in my family with gears v.s SS
Cheers Ed

Why would you? The manufacturers do it for you.

what do you mean what do the manufactures do for me, provide a geared weight?
haven't converted my one to SS yet and want the numbers mainly to argue with the family

Yes, Shimano state Dura-Ace Di2 7970 weighs 2,219g however with my modifications and seat post battery conversion mine comes in at 1,820g

All manufacturers will quote a weight for the groupset.

 

[young Ed]

about 2000g+ then? for a mechanical groupset
Cheers Ed

 

[AndyRM]

I think SRAM Red is the lightest mechanical groupset you can get - 1,747g I believe.

What if I weight all the parts left over on mine?

Do not forget to drill, brakes, chainset, bottom bracket, seat post,etc.

Top end then yes. Bottom end then maybe double that.

 

[Supersuperleeds]

Cut your brake blocks in half, that'll save a gram or two

Weight saving isn't the only advantage
1. Efficiency is always the maximum attainable with chain drive, approximately 98%
2. Simplicity, very little to go wrong
3. Ease of maintenance and cleaning
4. Robustness, the likelihood of breaking a correctly installed chain in good condition is almost zero
5. Same experience day and night, just get on and pedal, no trying to work out what gear you're in on a pitch black rural lane
6. Improved fitness, and better 'core' strength and condition
7. Cheaper to maintain, unless you're an NJS junkie

Maybe others will add to the list......
