Concentration on light weight.

This appears to have been pretty stupid. I bought a set of Centaur carbon cranks that are square taper spindle cranks. I bought a Token bottom bracket.. The total weight of this setup is 4 ounces more than the weight of a Campy Ultradrive. The spindle BB spins freely like I haven't seen in a long time because most carbon fiber frames are not perfectly aligned side to side. This causes misalignment of the cup or press fit bearings and extra friction even with the very best cranksets. It took me 20 minutes to install the BB and the cranks and they spun completely freely with only the friction of the bearing seals to slow the spin.

I will certainly keep you informed of the finished bike weight as the small additional components come in. I bought a Campy cable set and a Dog Fang which protects the frame from derailing to the inside. I somehow misplaced the bag that contained the brake recessed mounting bolts and had to order one that would fit the rear brake on. I will have to contact Look to obtain a new cable stop since one of them is broken.

I will NEVER again buy a tubeless rim or tire. They are so difficult to mount in the shop that they are impossible to mount on the side of the road. I have broken so many plastic tire levers that I can't begin to count them. The old red plastic holder with three levers in them have ALL been broken and I had enough of those for a half dozen bikes. The heavy duty levers have broken at least four and these are very difficult to use since they are thicker to keep some strength.

The latest Chinese carbon clinchers are extremely nice. And a fifth of the price of expensive American versions. I don't mind paying a premium for Made In America but not THAT much.

Some of the older ways of doing things are better. But they seem to have fallen by the wayside in a blind attempt to save so little weight that it isn't worth it. I suppose if I was willing to pay the price that Token could supply a spindle bottom bracket with a titanium spindle and fully ceramic bearings and there would then be no difference in the weight. The questions arises, "Why"? Bikes are now so light that the weight difference it more than made up for by your coffee stop and sandwich.

20 minutes to install a square taper bottom bracket and crank? Don't move to Madison in your quest to get away from communist California and apply at Andy's shop. I'm sure he won't hire a mechanic that slow. 2-5 minutes to install a sealed square taper bottom bracket. Put teflon tape or grease on the fixed cup threads. Screw it in. Put teflon tape or grease on the adjustable cup and screw it in. Bottom bracket done in 2-5 minutes total. Grease the tapers and screw on the crank arms. 2-5 minutes total for both arms.

Strongest tire levers on earth. Never break them. But they are metal, so maybe you might not want to use them on carbon rims.

I would advise you not to become a bike mechanic If you believe that you can do a proper job installing a carbon and aluminum spindle BB and crankset in 5 minutes. Do you suppose it is your intent to strip the splines on the BB so that it can't be properly tightened?

After a few hundred iterations (proper tools, good

faster.

You have to spend fifteen minutes thinking about whether to grease the tapers. Or not grease the tapers. Or grease the tapers.

What sort of workstand do you have that would hold the bike solid enough that you could lean into the aluminum splines with enough force to make sure that they don't strip or round off? I have the same workstand that all of the shops around here have and none of them allow that and the ability to turn the bike around and access the other side.

Although I would normally grease the threads, if the BB threads in by hand easily (meaning the threads are clean) I never do that because you have loctite compound of some sort on the threads to make sure it doesn't move - since it is BST threads if it moves it can overtighten and become impossible to get out. ISO tapers are so steep that you shouldn't need to grease them. Putting grease on them can actually prevent a solid metal to metal contact..

The questions arises, "Why"? Bikes are now so light that the weight difference it more than made up for by your coffee stop and sandwich.
20 minutes to install a square taper bottom bracket and crank? Don't move to Madison in your quest to get away from communist California and apply at Andy's shop. I'm sure he won't hire a mechanic that slow. 2-5 minutes to install a sealed square taper bottom bracket. Put teflon tape or grease on the fixed cup threads. Screw it in. Put teflon tape or grease on the adjustable cup and screw it in. Bottom bracket done in 2-5 minutes total. Grease the tapers and screw on the crank arms. 2-5 minutes total for both arms.

Strongest tire levers on earth. Never break them. But they are metal, so maybe you might not want to use them on carbon rims.
I would advise you not to become a bike mechanic If you believe that you can do a proper job installing a carbon and aluminum spindle BB and crankset in 5 minutes. Do you suppose it is your intent to strip the splines on the BB so that it can't be properly tightened?

I'm with Mr Seaton.

After a few hundred iterations (proper tools, good
workspace) it ought to be as quick as changing a tire if not
faster.

What sort of workstand do you have that would hold the bike solid enough that you could lean into the aluminum splines with enough force to make sure that they don't strip or round off? I have the same workstand that all of the shops around here have and none of them allow that and the ability to turn the bike around and access the other side.


Doesn't matter much and we use a few different designs.
Mostly, one pulls up on the wrench while pushing down on a
chainstay or something. Same principle as moving a
recalcitrant pedal; the wrench is in one hand and the
opposite side crank arm in the other.
