I'd be interested if anyone has successfully used a IRD triple with a
wide-stayed Riv or otherwise, and what bb and how was the chainline? I
expect that with a sufficiently wide bb spindle the rings would sit
considerably further out than those of the XD2 or whatever it is on a
107 or 113. But if you could center the middle on a wide stay'ed bike,
I'd be interested in it for the Fargo, using the middle and inner
positions as a wide range double (well, something like 38/24). As it
is, the X2D works fine with the outer sorta inward-biased so that I
can use it with more of the cogs as the main ring; the 36 is for
climbing and the 24 is for hypotheticals.
As for someone's comment that the X2D is a lot cheaper even than the
IRD, well, so it is, but it's not as nice looking, for one thing, and
the IRD is a nice middle term between the XD2 and the Herse, no? That
said, the X2D is a decent enough crank, and since I use the 46 for
most by far of my riding, chainring wear is a minor issue. And
chainrings are relatively cheap in 110.
Moving along: don't y'all think riding with loads up hills, pedaling
low cadence, hi-torque, is great fun? Or perhaps I'm an outlier, but I
swear I like pushing the Fargo up an incline with 30 lb as much as I
like spinning the gofast on the flats. Well, pushing the gofast up a
hill is even more fun. Just got back from a grocery run.
Moving further: Silver bar end shifters: wonderful, the best I've used
and I've used many. My 7 speeders are built with 9 speed spacers (with
2 between big cog and flange) and yet they shift them very well.
Occasionally there will be slippage, but that is due to the Hyperglide
teeth catching the chain very slightly off center; the long Silver
arms allow you easily to push a very small adjustment in the rear
derailleur's position.
