I have Suguino XD600 26/36/46 on 3 of my bikes and have never had a problem. My one trike has over 20k miles and the chainrings are as straight as the day I bought it. Can't say the same for the one it replaced. Shifting has always been on the money and I have a mix from Sram. Shimano and Microshift. I have no experience with a double but shifting from 26 to 46 is smooth. My 1st purchase price was about $100 from Jenson. My last was about $125. To me this Suguino crank is quite reasonable compared to others and $140 seems to be a fair price. FWIW I first learned of this crank from Rivendall and they were only $5 more than Jenson.
