BB30 question. Can somone clear the confusion

Road Cycling “It 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.” -- Ernest Hemingway

BB30 question. Can somone clear the confusion

I'm looking at two bikes. Bianchi Sempre and the Wilier Izoard. The Bianchi is a BB30 the Wilier is standard. My question. Is BB30 a little gimmiky? Guys at more than one BS said Campy does not even build for BB30. The Bianchi uses an FSA Crank because of this. The rest of the group is Veloce. With the Wilier, I can get it all Campy. Just wondering if I'm over thinking this.

I've got BB30 on my new Specialized and I do my own bike assembly and repair. BB30 allows for a lighter frame. It also generally allows for more heel clearance -- although I'm not convinced that's a meaningful plus. Some claim BB30 cranksets are stiffer, but this has generally been disproven in published tests.

"Standard" external-bearing threaded bottom brackets are extraordinarily easy to assemble and disassemble. It is difficult to get one wrong. BB30 takes a bit more time to assemble and disassemble, it's more of a hassle, and there is greater potential to get things wrong and mess something up (possibly including the frameset).

If the small weight difference isn't a huge deal, I definitely favor external-bearing threaded bottom brackets. They are simple and easy to service -- and they don't pose the same risks to the frame if the mechanic makes a mistake. If weight IS an issue, or if the bike you want comes only with BB30, I wouldn't hesitate to go with BB30 (obviously).

I dont care about the weight. Thats not going to make a difference, to me anyways. I just dont want to get something and find out in a year the standard brackets are no longer supported because the industry went to BB30. Thats my only concern.

Why didn't you say so?

The industry is so fragmented, I don't see standard BB's going away anytime soon. I could definitely see one or more of the BBxx bottom bracket spec's going away, though.

So if you yook a look at either bike, the BB30 issue would not be of any concern in your choice? So if I favour the Bianchi, I should just go with it regardless of the bracket? Its FSA. If I want to upgrade to full campy then I need to go with those insert things, and I'll prbably want to go full campy at some point

I would have to say that I don't like the idea of the adapters. They may be fine, but it seems a great place for squeaks and other issues to develop. According to some on this board, the adapters have a tendency to develop squeaks. My LBS does not recommend using them for exactly that reason.

Guy at my BS said the same thing.

I've got a Cannondale 2009 Synapse with the English Adapter in a BB30 shell and a 2010 Supersix with no adapter (BB30) along with a Quarq Cinqo S975 (BB30) Crank based Power Meter. That means I can't use the PM on my Synapse which sucks. My TT bike, which I bought this year, is BB30. I knew I'd be going with BB30 from here on out back when I built the Supersix. So my advice is, get the BB that you want to stick to for at least the next bike. GL

I'm all confused about BBs myself. As important to what they do they're sort of mysterious as to compatibility and such.

I've got a bike with a FSA ISIS BB and and chain ring and I want to (at some future point) swap it out for a Campy Mega EXO (because I'm a snob, no other reason, OK) BB and chain ring. I think the threads and the size are pretty much the same but I don't know that for a fact. They don't make this stuff real transparent...

My LBS says adapters aren't a problem. I'll find out early (I hope) next week, and report back.

i like bb30 because it's an open standard, you can buy bearings really cheap and it's light.

Campagnolo makes press-fit adaptors so you can use their cranks on a BB30 frame. Based on the materials used there should be no problems with squeeky BB's.

That would be a good reason to use an adaptor (i.e. to get rid of the FSA).

Personally I have a BB30 frame with DA and I use an adaptor. No squeaks yet. But there are at least three ways of adapting a BB30 frame for regalar Campy or Shimano cranks designed for standard outboard bearings. Some are probably better than others.

I drank the kool-aid and thought I needed a BB30 bike. After I bought one I realized I couldn't tell a lick of difference to my riding experience (the new frame and components by far outweigh and difference than a BB standard). Plus now I have a setup that I can't work on at home with my existing tools. I like the frame (CAAD9) but if I had to do it again I'd prefer a standard BB for the ease of maintaining it myself.

So, Bob, if I have an FSA ISIS cartridge BB and want, say, a Centaur 10 chain ring I'd get a Power Torque outboard BB shell? Is this analogous to BB30?

Heh - it's not like BB30 frames need any additional help in the squeaks and creaks department.

BB30 has nothing to do with what you've got. You've either got a standard english or (less likely) italian BB shell built in to your frame and you'll just need the correct Campy BB cups (english or italian) and the new Campy cranks.

I love my BB30 bike and have had zero issues after using some Loctite press fit bearing compound when installing the bearings. The bearings themselves are an industrial standard and super cheap if you order them from a bearing supply company. I also ran the Wheels Adapters (I think) plastic spacers to use a Shimano DA crank with this bike initially; no squeaks, no issues. A friend of mine has done this on at least 3 BB30 bikes with no issues (he runs a bike shop, gets BB30 frames, but prefers DA cranks).

I bought a BMC Race Machine frameset (BB30) and it actually came with a FSA press-fit adaptor sleeve (not installed) in the box of goodies. So the frame manufacturers know full well that many people are going to adapt their bike to standard cranks, and condone it.

All the talk of standards is funny. JIS & ISO Tapers, Hollowtech, GXP, MEGA EXO, Powerspline, ISIS - all screw into the same 68mm thread (English) bottom bracket, or can be purchased for 73mm (Italian) threads. Cannondale came up with BB30 as a design improvement, and shared it for the good of the cycling world. Hey wait, they had to share it, or SRAM, Shimano, FSA, and every other crank manufacturer wouldn't make a crank just for Cannondale. Drink the Kool Aid if you wanna, and it may very well be stiffer for a given weight. Or it may be marketing fluff.
