Hi Guys,

Searched like crazy but just could not find this info.

Am building a Titanium touring bike and was looking at the 4700 for the triple. Any idea what the entire groupset would weigh? I know tourers should not worry about weight, but I'm also making this a reasonably light weight bike to enjoy on days in between the actual luggage carrying touring.

Well if you need reasonably light weight bike you wouldnt consider tiagra or 105 so no need to get bothered on weights. Just buy the best that you can afford. I think the 5800 is little bit more expensive and super all around, try to go for it.

You missed the point. I 'need' a Tiagra for the triple. I don't want a 5700 or 6700 series, and the 5800 and 6800 are 11 speed without triples.

Actually the Ultegra is also very affordable, but they have no triple. For a titanium bike, I would love to go Ultegra or Force but no low gearing with them. Any other suggestions and I could try that. The 6800 does not even work with a MTB RD, so no choice for a big cassette there either.

Best that you can afford is singularly bad advise sometimes.

Apex with a wide range cassette and a compact would be the light/cheap option.

I'm sure Tiagra would be effective and durable but weight is not it's strength. My Googling found this -

Tiagra 4600 weighs 943g (standard) or 903g (compact)
5700 105 compact 723g
SRAM Apex 890g (heavier than I expected I admit)

I'd imagine that the Chainset would be the biggest problem for weight and a Triple would add even more.

34/32 is not enough when carrying luggage. For me at least.

Will Force 22 shifters work with a MTB RD?

There is an adapter just announced that will allow you to use Shimano MTB dérailleurs with road shifters. You could feasibly go up to a 44 cog with this.

If money no object, just functionality, xtr di2 (although xt di2 rumoured for the near future) with a triple and wide range cassette onto road di2 levers :lol: :lol:

Hehe, interesting. Never thought of that. Money no object, but not to that extent.

Well, these are the weights that I got from Rosebikes. Wonder how accurate they are. So, if I go Rival with MTB RD, I save about 450 grams but lose a couple of the lowest gears.

Tiagra Triple Rival Rival with X7
Shifters 510 335 335
Crank 1015 845 845
FD 114 90 90
RD 275 195 280
Cassette 300 300 300
Chain 267 267 267
Brakes 385 300 300

2866 2332 2417

Total bike weight would be

Frame 1300
Fork 330
Groupset 2866
Wheels 1750
Bar 260
Stem 160
Post 300
Saddle 222
Pedals 275
Cables 250
Tyres 500
Tubes 200

8413

Any glaring omissions? 8.4 kg for a light tourer is fairly good I should think.
