Campy 1x Road conversion

I have been slowly acquiring parts to build my wife a 1x10 or 1x11 road bike with S&S couplers. That changed this week when I was able to get a brand new Raleigh Grand Prix with the Ritchey Breakaway system and a Campy Veloce 10 drivetrain, complete bike for $1100!

I do almost all of my own mechanical work but my bikes are all Shimano (old 8 speed Dura Ace with downtube shifters.) My question is:

If I want to convert her bike to 1x10, I have a single speed crankset, can I just install it and remove the front derailleur? In other words, are the brifters spring loaded so they won't flop around if the shift cable is missing? My original plan was to go with SRAM since they have matching shifter-less left brake levers.

I have done 1x8 for a commuter utility, but I sincerely wonder why would you would change 2 x 10 to 1 x 10 in this instance? What benefit are you getting? the set up right now seems to give you a lot of flexibility. you ride in the big ring for most riding and still be able to drop to the small up front if you need low gearing. Going 1 x 10 is going to give you less range one way or the other.

The reason is simplicity. My wife is currently riding a 3x8 setup. We are nearing 60 and we do 90% of our riding on paved Rails-To-Trails trails. So we ride slow over consistently flat terrain. I used to race and have been riding seriously since my teens. She has been riding for about 10 years but the still has trouble shifting -- especially knowing when to shift her front derailleur.. Also since this will be her travel bike it's one less thing to mess with when assembling/dis-assembling in hotel rooms.

Yup, what's the point of removing gears on a bike that's all set up ?
Let her ride it as-is, then decide if any gearing changes are needed or desired.

She can just leave it in the small front ring and not shift .

There shouldn't be anything front gear related needed when travelling.

Your plan should work if that's what you want.

Yeah, you guys are right. We'll at least try it before making any drastic changes. If I were building the drivetrain from scratch it would be SRAM 1x11 but since it will have a perfectly good campy 2x10 ...

Yes

In response to original question, you don't need to replace left brifter, it won't flop around .You don't need to change cranks either. Just remove one chainring. Ran a 1x9 Camp system on my commuter bike for years. I would advise either getting chain keeper or leaving front derailleur on as chain occasionally will jump off.

Or use a narrow wide chainring. But he's right, the chain will fall off during a shift and trust me you don't want your wife going down because you didn't use the correct setup.

The best advice given is to let the wife decide what she wants.

Personally I question this drive to fewer gear choices just to be able to be lazy and not shift the front. But then I learned how to shift when we didn't have indexing, shift gates, ramps or pins. If you wanted the shift to be smooth you worked the bike so it was. If one must remove a ring then I strongly suggest the remaining ring be a design that doesn't promote chain shifting and the use of a chain retainer (ft der or guard/guide). Andy

A 1 chainring setup, would sit on the chainline center,
(like the middle ring of a triple)
and so have equal distances of lateral chain flexing,
to the smallest and largest cogs, on the ends of the cassette cluster..


As to the shifter, in the brake lever ,
just take the shift gizzards out of the left lever .
put the bits in a bag..
