I had that same cracking on a Specialized (Sugino) Flag triple crank, solved
it with some judicious filing, and have been riding it for a couple of decades
since with no further sign of cracking.cheers,Andrew in Sydney

The crack on Campy Record/Super Record spiders was the result of the very
sharp edge at that location. A common fix back in the day was a few minutes’
work with a round file to take the edge off that part of the crankset.

Something not mentioned in this discussion is the quality or consistency of
chainring nuts & bolts. I have sometimes switched out nuts and bolts when the
nut tool isn't making a tight connection. Steel or aluminum? Does that make a
difference? I don't know; I've always used steel.

It does minimise the problem that some cranks have/have had where cracking
develops at the join between the crank and adjacent spider arm because of the
acute angle between them. I can remember having to retire a couple of
Campagnolo Super Record cranks that I was racing on back in the 1980s because
cracks had developed at this point. e.g. - This image is from pardo.net, but
it's identical to the cracks I found.

That said, it works out great for me that so many people seem to have such a
hard time with hidden bolt cranks, because I've never had a problem with it,
and your shared struggles has got to help drive the price down for me. Walking
around my garage, there are four bikes with hidden arm Ritcheys, three with
hidden arm Sugino, and two with hidden arm Campy.
Ditto here. There must be half a dozen bikes in our garage using cranks with
the hidden chainring bolt behind the arm, and I've not had any problems
changing chainrings on them.

[RBW] Silver2 cranks!

2023-10-25 Thread Bill Lindsay

I stumbled upon the News Blog on rivbike.com and was glancing at Roman's 
Legolas.  He and I ordered ours in the same size at the same time, so I 
always regard his as the twin sibling to mine. 

Anyway, there's a sneak peek of a lighter, road-ish, Silver2 crankset. 
 Looks pretty cool!
