Tires, tubes, rims, and hubs have to match.
FD and RD have to match.
Ditto brakeset.

Ideally the same groupset but not necessarily the brake set or Crankset. With my type of riding those two things matching aren't Super Necessary.

But just because... My '86 Ironman is a 6 speed, my '87 Ironman is a 7 speed, my '88 Ironman is an 8 speed. And it kills me that my '89 Ironman isn't a 9 speed BUT I'm working on it.

It was Campagnolo, except they called it a "gruppo".

Wonder why stems and bars were never included. Seatposts were.

I'm not really OCD but I try to be respectful. Feasible period parts are my preference. I don't care much about OEM. Restomod with a few modernish parts can be OK, but I've grown less enthusiastic about it. I can ride my modern classic style bike if I want modern parts. I won't be putting Ultegra on my Masi anytime soon...

Real world racing bikes BITD got their parts swapped out all the time, as parts wore out or crashed out. They often were a mix of whatever components you could hustle that did the job. Wheels and rims were gone through quickly -- almost disposable. It's funny for me when I see someone complain that the 1977 DeRosa or whatever doesn't have the original rims anymore. No kidding. So yeah I want parts that fit the spirit and look of the bike, but they don't have to be the ones in the catalog. Serious riders usually built up their own bikes from framesets anyway.

I'm not sure it was OCD, but when I restored my McBain track bike everything had to be available in 1982:



I conceded on the tyres (Paselas) and spokes (DT Swiss Competition.) Chain is debatable (HKK.)

My perspective: With every new bike we have a possible direction and a goal to set.

If I set my goal to be period-correct or full resto, I'm going to get OCD and obsess on every little detail including date codes.
If I set my goal to go lightweight, I'll probably aim to weight-weenie things whether it's period correct or not, although I may get OCD on the paint/decals/chrome.
If I set my goal to go gravel bike, I'm probably not going to do much at all in the way of correcting paint and I'll focus more on mechanics and wheels.
If I set my goal to build as a daily rider or commuter, I'm going comfort and ease and really don't care about the rest so much.
If I set my goal to flip the bike/resale, I'm going to go with whatever is quality-but-budget and will last longest knowing the new owner could neglect all maintenance.

There are probably other cases, but in the last decade, those are the 5 big ones I've been through.

The end result in my worl hinges greatly on what I'm handed from the getgo.

I tend toward OCD and will use 'adequate' components until I get proper ones. I just don't obsess and lots of time may go by before the 'proper' component is found. All the while the bicycles are lovingly maintained! I love my bicycles! lol

Cyclist753

Say it ain't so...lol! I always tended toward the 'mystical qualities' Campagnolo 'Camp'!

Put together this , a 84' Centurion Comp TA . Got it as close as I could , this was my first build it to show room stock bike . I came close but no cigar .

This has been eating my ass, and not in an enjoyable kinda way. One of my favorite bikes to ride around right now is (and has been for a while) a titanium Raleigh SP1000. I know that probably sounds weird for a French-loving toolbag like myself but, I gotta be honest.

Previous owner of the bike went hardcore weight-weenie on it, upgrading a lot of the bike to Mavic components. Retrofriction Mavic levers, 840 or 841 RD, starfish crank, but it's been absolutely destroying me it's got a damn Deore FD. I have two or three braze-on period-matching 8xx FD but no clamp-ons.

And while there's nothing wrong with the 500 EX levers/calipers (they work and look great on this bike!) I'm also like "damn I wish the brakes also matched!" but trying to find the Mavic branded 440s (Modolo) at a decent price or even the DiaCompe Mavic/Suntour calipers and levers at a fair price has been damn near impossible the last couple years.

The OCD is definitely high here. But point of all this being, everyone's idea of OCD is different too. And maybe the difference is in your end goal? Like, I'd love to have cohesive parts on the bike I ride the most. I am pretty anal about not mish-mashing stuff.

I routinely - and on most of my bikes - run different front / rear wheels and tires.

A taller frame shifts more of the rider's weight to the rear because of the seat post set back.

Most flats seem to be on the rear. and I love the feeling of a lightweight front wheel.

So, I run a heavier rear tire and a lighter front on most of my bikes.

Seven bikes are "fairly"period correct here. OCD to the 5th power.

McLean Perfect Pleasure
Tommasini Sintesi
John Hollands Sportif
Yeti FRO
Bridgestone MB1
1983 Specialized Stumpjumper Sport

The others, not so much.

Mismatched wheels bother me although wider wheels in back on a touring bike are ok as long as they're the same color. Mismatched tyres don't bother me as long as one isn't gumwall. Other than that, if it works, I'm good. Suntour, Shimano, Campy components are fine if they get along. Indexing shifters excepted.

You folks would hate my bikes. I've had a bike with one dark rim and one light rim. I've had a bike where the sidepull brakes were mirror images of each other. I have an Ultegra/105/Sora drivetrain on one bike.

What would this site be without your build thread on that Raleigh you've been working on like forever, right?

This is just a classic BF thread:

I have OCD but also a short attention span. Works very well for me.

What were we talking about?

rootboy 

All this parts decision stuff is the fun part. Right?

bikemig 

Wait what about riding the bike once you build it?

Being OCD about these things is what about I love in restoring old bikes. For me the most interesting bits are the small details like brake cables and fender bolts. I'm now in a middle of restoring a barnfind colnago and If I would have all the money in the world to sink into this I would try to build it so that all the stamps of the parts would be from the correct year.. For now I have settled just to have the period correct parts with the markings from various years since I already had those from previous projects.

Gotta say, that decal on the pump is the bee's knees. Don't know if it was common bitd but just an interesting little touch.

Pop quiz.

There are two component choices here that are driving me crazy. One very obvious, and one for the more neurotic:

crank_addict

Well, there is this French disease and although warned, I kind of like it....

Spare the gory details but the bar tape is correctly wrapped, starting from the center and sans finishing tape.

mpetry912 

The decal and striping on the pump was done by Ruth at CycleArt. Previous owner spec'ed that out. That detail was not done (at least from the factory) BITD.

Glad you like the bike. It's a bit OCD but fun to ride. Like driving an old Jag.

Or tires that are branded for another marque.
