The most likely complication is that proper shifting using a compact crank set requires that the front derailleur sit lower on the seat tube. If your frame has a braze-on mount for the front derailleur it is likely too high to work with bolt on derailleur, and may get in the way if you try to use a bracket-mount front derailleur.

Shimano publishes a compatibility document. Go to URL http://productinfo.shimano.com/#/ , select "compatibility" to download a document "2015-2016_Compatibility_v010_en.pdf" According to that document, you would also need to change you crankset, your front and rear derailleurs, and possibly your bottom bracket.

You should just be able to replace the chainrings for 11 spd ones. You can also get 9-spd 105 shifters if you just want tidier cable routing (I assume you mean internal as in under the bar tape) which would let you keep the rest of your groupset as is.

24mm refers to the diameter of your spindle (the rod connecting the two cranks) You can look for more details on this chart: http://www.competitivecyclist.com/images/sizing/FSA___RD_CRANKSET_STANDARD_18x24_20140306_reduced_size.jpg Hope this works for you :-)

Chainring bolts do need to be checked/tightened at regular intervals, it's a part of the maintenance. It it quite possible that they loosened in that 500 miles time and worked their way out; it's surprising that it wasn't more noticeable before it came undone. Some of the early indicators of loose chainring bolts include creaking and a rattle. You can ...

Drilling a crank that old is not a great idea. They weren't that strong to begin with and 40+ years of use hasn't made then any stronger. I would not do anything to further weaken them. To be honest, if the pedals are frozen I'd think twice about using that crank. Aluminum corrosion expands and can create stress that crack the material ( similar to the way ...

For me the big advantages of the triple (eg 52/39/30) are: The two cogs 52 & 39 on the front for almost all riding - a classic double with ratios not too far apart, 39 ideal for rolling country. I never spin out on downhills unlike compact riders with their 50/34 30 on the front for very steep hills or when I am weary/totally knackered towards the end ...

Tap another 5 holes is not enough. There needs to be metal to space it out that I suspect is not there. Just add a spacer would probably not handle the load. Even if you do attach are you sure there is room on the bike? Are sure you can find triple front derailleur for that bike? If you get past all that you may end up with chain line issues. ...

I have lost a bolt from my a chain ring and have been completely unaware of it for weeks. I had to have it pointed out to me by a mechanic. In retrospect there was a little more rattle than normal. I guess it is possible one could lose two and not know it either. Once two come off there would be more rattling I would guess. The amount would depend on ...

I installed that Praxis BB30 converter on my Cannondale and I will never look back. I switched to a Shimano hollowtech II crank because that's the one I had lying around. Not only does it feel more rigid, but the bb30 was hopelessly noisy no matter how often I cleaned it, and the Praxis BB has been silent so far, the bearings seem to seal better. So yes, ...

I have used Shimano 10 speed cranks with 9spd chain, derailluers and gears. Without actually having tried it with the Campy components you list, I see no reason why it shouldn't work. The only difference between 9spd and 11 spd chain is the exterior width of the chain. The interior dimensions are identical (i.e. 3/32 of an inch wide, 1/2 inch long). The ...

I'd say no. If the frame had a screw-in BB shell you could simply fit a tapered axle and bearings. Looks like you'll need a new chainset (that comes complete with axle) - however you could get rid of the cheapo BB71-41A (MTB type - why would anybody fit this?) and fit whatever bearings suit the chainset of your choice

A square taper crank set with triple chain rings is a straight forward search item in google, or the local bike shop. If you are aiming for a pure drop in replacement, make sure you get the same tooth count on the chain rings, and the crank arms are the same length. You mentioned the BB is only threaded on one end. I suspect this means you still have the ...

I had the same issues with my "72 and '75 Peugeots, although I'm sure this isn't related to just them. The second answer is about what I did and worked better for me. I liberally used WD40 and a cheater on my wrench.
