Bottom Brackets

We all know that threaded BB are basically gone with the standard CF bike
offerings. Personally I find of course if buying a bike in the past I always
went for the English bb now my choices are limited. We all probably think as
I do that the standard thread BB is by far much better. So given the
constraints would you all prefer a BB30, PF30, BB86, OR A 386EVO. From my
research it would appear the best choice is a PF30 and if using shimano
cranks I would go with Praxis adapter. This seems to be the easiest to
service and least chance of squeaking.

What is the consensus here or should I just stick to custom steel or Ti
bike and avoid the problem?

take up swimming

I do swim but slow and so far I have not had to deal with bottom brackets in
this endeavored. I was thinking mostly about bikes what kind of bike do you
usually ride?

You can fit your Shimano crank on a PF30/BB30 BB with the Wheels Mfg. adapters. http://www.amazon.com/Wheels-Manufac.../dp/B00D5DQ3H8 Simple and cheap approach.

The Praxis Works BB adapter is a nice piece, too, but it creaked a lot on my CAAD 9. I've got one now on a Roubaix with a Praxis Works crank (and a novel spindle standard -- M30). http://www.praxiscycles.com/cranks/ It works great, so the issue with the CAAD 9 might have been unique.

Pick the bike you want and then get the appropriate BB adapters to go with your Shimano cranks. I wouldn't pick a frame based solely on the BB standard.

I do worry about future crank/BB availability, but I don't know if that worry is reasonable. I think PF30 will probably be around for a while. I don't even know who still builds with threaded English BBs.

the layoff from injury would progress with swim ex not decline ....if the activity level was around 100 miles no problem then you would regress....gaining warmup time by abt 15-20 minutes a week. The Krebs cycle chemistry weakens.

Whatever are you guys on about? Shimano makes threaded English bottom brackets, just like they always did. Here's one I favour in stock from the world's biggest mailorder bike component dealer. http://www.chainreactioncycles.com/i...t/rp-prod71369 Chainreactionbikes also has the UN-26, the world's bestselling BB, square taper and British thread, of course. You want something with a fancier name, here's the Campy version, British thread of course. http://www.chainreactioncycles.com/i...t/rp-prod85637 Here's a Stronglight, made in a huge factory in Czechoslovakia, available in plastic, ali and steel to taste: http://www.spacycles.co.uk/products....d=m2b0s110p140 http://www.spacycles.co.uk/products....=m2b0s110p1933 http://www.spacycles.co.uk/products....d=m2b0s110p141 This stronglight JP400, under various names, is a standard on what Lidl Tommi used to call "bikes for the Euro elite" because bike manufacturers with extensive test facilities of their own, Stronglight and others, don't see why they should pay more for a fancy name that is no better than this well-priced BB. I've had this one on two pricey bikes and they're a fit and forget item.

European custom bike makers fit square taper, British threaded, sealed bearing bottom brackets as default, because they just plain work.

You want the rest of that crap that's intended for fashion victims who take what they're given, you have to ask for it.

The apocalypse is here! I can't find a square taper bike bracket at my boutique bike fashion pusher.

I was wondering which major manufacturers made frames with standard threaded BBs. Probably mostly steel makers -- Surly, Soma, etc. Linskey (Ti) uses PF30s. AFAIK, all the CF makers use some form of non-threaded BB.

Ah, I see. Thanks for the enlightenment. Yes, I don't even consider anything but a lugged steel bike. But the question does arise, why can't carbon fiber makers just use a threaded insert at the bottom bracket? In marine and automobile work threaded metal inserts have been standard FRP and CRP practice for half a century or more. Those little doughnuts weigh almost nothing..

No technical reason at all, and some makers do. A push-in
system can be lighter, cheaper to make and favorable to
marketing.

(Marketing essentially is, "The crap we sold you last month
is no good. Here's the new one.")
