Is it a sin to mix groupsets?

Notices
Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Is it a sin to mix groupsets?

For example, Ultegra cranks and cassette with 105 shifters and DRs?
Itís a 105 level bike.
In this case for the purposes of a crank-based power meter of said brand.
just considering some options and it made me wonder.
thanks!

Forgive me, Father, for I have sinned:

I have a SRAM/Quarq crankset on an otherwise all-Ultegra bike. I have a Stages crankarm on an otherwise all-DA bike. I've got a CX bike with Shimano/Stages/SRAM. My kid's road bike has a SRAM crankset on an Campy Chorus/Centaur bike. Oh, and my kid's CX bike has an FSA crankset on a 105/Tiagra bike.

Many shifter/derailleur combos don't communicate well with one another; however, 105 and Ultegra share the same articulation/cable pull engineering so you're not just good you're great! I once shifted an Ultegra derailleur/cassette combo with a Dura Ace shifter. Same thing.

I am running a Sugino crank, Ultegra chainring, Deore cassette/shifter/DR on on of my bikes. You have tons of flexibility on which cranks will work. Knock yourself out!

The bike manufacturer's do it all the time.

I too have a 105 FC-5800 crank with chainwheels from a Ultegra FC-R8000. Spider profiles don't match up, but I figure you won't be able to tell when I pass you. <grin>

I've got a bike with Chorus everything except a Centaur cassette and a Veloce rear derailleur. I have not yet been excommunicated, but then, this pope seems quite tolerant.

I haven't gotten any notices myself and I've got potenza derailleurs and brake levers/shifters with shimano brake calipers, chain, and cassette.

Interesting find that SRAM shifters will work with an Ultegra RD. What speed are they?

As long as the non-matching replacement parts are an upgrade, it's all good. The only sin is a downgrade.

The only real sin is putting anything other than Campy on an Italian frame. And no, Team JumboĖVisma doesn't get a pass on this! Some things are more sacred than sponorships and money.

This is only a minor sin, nothing too drastic. Unlike these other two who have so badly mixed things they've got a straight ticket south. My newest build is Record shifters with Chorus drivetrain, kmc chain, and completely un-Italian White Ind. Hubs. Really isn't a bad thing to build to your budget or goals.

Quite true. Just make sure it's the Italian made campy. There's nothing wrong with 8 speed.

I'll have you know that my 11-speed Chorus group was made in...<checks Internet>...uh, I dunno, but anyway, it's totally Italian designed, so it has a soul.

Unlike that Japanese stuff striving for nothingness and nirvana. There's a catechism for Campy. There are rules. None of this "discovering your inner Buddha nature" nonsense for the Italians.

Going before an OCD Tribunal ?

if you pay The Church ahead of time your sins are pre-forgiven,

it's called Indulgences , and in the middle ages, it financed building the great cathedrals .. the Vatican Etc.

My 1993 Trek 5900 was the flagship model for that year and carried a mishmash of parts. Whichever was lightest went on the bike: some Dura Ace drivetrain stuff but downtube rather than integrated shifters to save weight; Dia Comp brakes; White Industries titanium BB; Chris King titanium headset; Ibis titanium threadless stem, one of those odd duck 1" things that superficially resembled a quill stem. Looks like Trek went for minimum weight first, with price only a secondary consideration, and no regard to group marque.

Pretty much the same way hill climb specialists approach their own custom builds.
