Gianni really took it in the shorts after trying to sneak his way along with a stealth EPMS. Like an alcoholic falling off the wagon, the poor fellow can’t quite come to grips with the comfort of his old friend, the saddle bag. The solution lies in finding a light toolkit to carry along with him on his rides, one that fits in one pocket in totality.
There is an elegance in minimalism; a small multi tool with just the right combination of appliances is a beautiful thing. Latex inner tubes are a nice way to keep the spare tube package small and light. As are some compact tire levers. Certainly luck favors the prepared, but if you follow that to its logical conclusion, you will need something more than a saddle bag to carry your workstand, grease gun, and headset press. The Velominatus maintains their bike, and takes every reasonable precaution to replace those parts that might fail during a ride. It is what we do; the bicycle is our lifeblood – care for it, and it will care for you.
An equipment failure is, however, always surprising – in particular to the rider. Take, for example, my pedal which unwound itself from the spindle this week. Normally, when you push, the pedal follows a nice arch and the bicycle goes forward. Not so, should the body no longer be affixed to the axel.Should this occur, the pedal will move outwardly rudly and inflect an unpredictable union of top tube and groin. It is remarkable how little forward momentum is associated with pushing on a pedal which is no longer attached to the bicycle. It is also, I surmise, not a particularly elegant thing to watch.
Speaking of inelegance and no momentum, I also once broke a chain link climbing a steep grade in the rain, while carrying with a heavy back pack. Should you encounter such an incident yourself, you will take note of the remarkably short amount of time it takes to stop moving forward and fall in a confused and cursing heap at the roadside.
The point is, accidents happen, and no matter how much care you take of your equipment. They will happen while out on the road, possibly while far from home. We learn from them, and we take the necessary measures to reduce the likelihood of it happening again. Take my pedal failure; I don’t plan to carry a pedal wrench in reaction to this incident; I instead have now added the pedal to my list of items to periodically check over. As for the chain, it had incurred some corrosion because I was experimenting with a lighter oil. I now take care to check for (and take seriously) signs of rust on a chain.
Be sensible, be careful. Take care of your machine. Kneel and flash the sign of the Merckx in your V-Kit before submitting to the road, and get a nice light toolkit with the right tools for the incidents that are most likely to happen. Maybe you’ll have a ride ruined through an unlucky event, but learn from it and improve your maintenance program rather than endeavoring to carry every tool known to the Velominatus.*
Vive La Vie Velominatus.

So...rookie question here.
When I purchased my Specialized Tarmac Elite it was outfitted with Shimano 105 except for the cranks and bottom bracket which were FSA Gossamer - BB30. At purchase I decided to swap out the FSA for 105 and I've always assumed that included changing the bottom bracket as well. I don't see much in the way of praise for BB30 on the internets so today I started thinking about my bike.
I took a close look at it and there it was plain to see...
"BB30 - SHIM" printed on the cup that connects the crank to the bottom bracket.
I assume that indicates an adapter was used to mate the BB30 to the Shimano cranks?
Is this an issue that should address? Or can it be addressed? Is the Shimano BB the same size as the BB30 or are bikes simply designed with a BB30 sized hole in them?
I should likely report that I've had zero issues with that aspect of my bike. I've put about 5000 km on the bike and the cranks still feel rock solid to me...no creaks (knock on wood).
Enlighten me!
I found this article that does a really good job of explaining the various BB configurations.

I'm still a bit foggy as to whether or not a Shimano BB could be used instead of a BB30 in my frame.
A Shimano BB would appear to be threaded into the frame whereas the BB30 is pressed into the frame?
Did I just get it?
@kixsand
yes.
You can run a shimano crank with the right adapter.
@mouse
You are correct. The pressed in BB30 held together but the crank failed in the center.
@RedRanger
very good explanation. The BB30 is pressed in. I run external threaded BB on my Specialized. Much easier to replace.
@kixsand
You have options

There are usually three parts involved; shell (what the frame is made for), bottom bracket (bearing interface between shell and spindle), and spindle of the crank. Shimano uses 24mm spindles, while BB30 bearings requires 30mm, so an adapter is put between them to make everything fit. There are dedicated solutions (Praxis), that will have larger bearings and a wider bearing stance, and don't require adapters.
@TommyTubolare
Option 3 is what has been installed on my bike - the Wheels Manufacturing BB30-SHIM adapter.
It looks like the second option would allow you to install a Shimano bottom bracket as it would change the diameter of the opening to 24mm and provide you with the threads to attach the Shimano BB.
Does the FSA BB30 Bottom Bracket Adapter/Shimano BB5700 combination represent any appreciable improvement over my current setup?
@ChrisO
I don't understand what's all the fuss about. You just press the cups i/o threading them and that's it.
