Which Groupset?

This is a quite old article about Campagnolo vs the rest of the world, but I found it very good and balanced: http://www.bicycling.com/news/featured-stories/italian-job

Thanks for this. Excellent read.

It's not unfortunately, otherwise I would. Then again, I'll be buying new wheels for it so it's always a possibility.

Why not campagnolo centaur? Looks a fuck load better.

Want the ability to use parts from one bike on another, don't want to mix groupset types etcetc.

Ah. Fair enough. Nothing wrong with 105 from what my mates that ride it have said.

Put 105 on the winter bike and Force on the summer bike.

Obvs.

Yeah but the Force is in pretty run down condition. Not so obvs. If I was to do that I'd buy Tiagra for the Surly. But again, isn't a bad option.

What's run down? Replace consumables (cables, rings, etc).

More that the shifters are all scratched. Mostly cosmetic, but the jockey wheels could do with replacing. It's all doable, I just like shiny new stuff ;-)

Ultegra vs 105?

I'd get neither and opt for the new 11sp Ultegra. 11sp is forward compatible for a good while yet, 10sp is on the wane.

are we talking hope or CK rear hub?

105 on a BMC Pro Machine...

Difference between 105 and Ultegra is pretty small to tell, they both shift and do it well.

105 with Tiagra part.

This I agree with

105 with Tiagra part.

This I dont for the BMC

Get 11spd ultegra if your rear wheel is compatible.

But this.

Your BMC is a summer bike, go the whole way by going for part you'd definitely want on the stainless steel bike.

If its CK wheels you can get 11sp conversion kit, not cheap but if put in perspective of 11 speed upgrade and 6800 being a bargain totally worth it

Hope hubs cant be converted sadly.

I thought the CK classic hubs can't be upgraded to 11spd. Which hubs do you have Jake?

This I dont for the BMC

You got Di2 on a touring bike uh may, shut up.

Ameys opinions on bike building are to be taken with a heart attack-inducing amount of salt

Jake, there's nothing to say that you can't mix and match - if I was doing it on a budget and wanted sram or shimano I would spend money on the mechs (force / ultegra) and brakes if you go shimano.

Seeing as shifters are the most expensive component, your best bet might be second hand 6700 ones. Collecting parts slower is always cheaper

I don't think the choice is between 105 and Ultegra 6700 because the price difference is real enough.

The choice is between Ultegra 6800 and Force 22 - both 11 speed and both about 40% off rrp right now.

I'd buy Force 22 and sell the brakes, use the brakes from your Pacer on the BMC and buy some cheap/decent second hand brakes for the Pacer. You'd come out with Force for roughly the same price of 6800.

Does no one here read what people write?
His wheels are 10 speed and are lovely ck hubs to ardennes rims- 11 spd conversion is expensive. Also - why would you want different speed systems on different bikes?

But lfgss is a place to espouse ill informed opinion rather than useful help.

Quite.
