It was that hidden fifth bolt on sugino cranks that finally motivated me to look for something else. I ride a lot of dirt roads and a fair number of rainy days so my cranks need a thorough cleaning a couple of times a season. A straight forward set of bolts is much easier to deal with and a true double is better than a triple converted to double with an outside chainguard blocking access to the ring.
Both White (under the DaVinci label) and TA make cranks that easily convert from double to triple but the White uses the same bb spindle along with standard rings. I'm not too worried about White rings disappearing, but even if they stopped making them, I'd just buy an extra. Size is no guarantee of immortality, unless you're a very big US bank. michael On Sep 9, 9:01 am, Garth <garth...@gmail.com> wrote: > I'll double the suggestion to use an XD2 crank and leave off the big > ring.
