Re: Drop bars - who uses the drop bit?

Did not a single competetive cyclist think to get into that position before aero-bars were invented? That surprises me because I have even seen city cyclists leaning their forearms on the handlebar of a Dutch-style bicycle when rushing to an appointment … but maybe they too only did that after Greg...

Any 10 speed Campagnolo rear mech is compatible with any Campagnolo 9 speed drive train after 2000. (levers with rounded hoods_)

Re: Chainring change

The special chainrings are also called "triplelizer" and can still be found at small shops and Ebay. Couple of years ago I bought one for my Campagnolo Chorus carbon double chainset (square taper) with 39 T and 74 BCD holes and it works perfectly despite the missing shifting aids. 74 BCD o...

Re: Should I replace or repair my broken original Brompton Archer 5 Speed hub?

Had teh same , many years ago, also a folding bike , and repaired it. A small bar in which the pulling pin screws was broken. Not difficult for someone who is familiar with SA 3 speed hubs.

Re: Campag/Shimano mix

That's why I use exclusively pre 2007 9 and 10 speed Ergopowers, they never gave me trouble the past 8 years and IF they do, I've numerous spares laying around.
Better avoid any Powershift Ergo's.
The 11 speed Ultrashift ones seem also good, but I don't need nor want 11 speed

Re: Bottom Bracket for a Campag Chorus Triple chainset (2006 year).

Main limitation is the size of the seat tube.
On a 28,6 and 31,6 seat tubes the 111 mm BB is fine, on bigger seat tubes you'll need the 115 mm.

Re: I should really listen to my own advice more...

Poor construction of that frame....
I guess the designer/builder of that frame never saw this animation, it shows that the lower gussset is completely unnecessary:
