Re: [RBW] Cranky Crank VO Replacement
I assume that if you buy the XD 600 from RBW you get stock sugino rings, not the new (and very nice) Silver rings? Also, despite what their web site says, I find ramps and pins help friction shifting, not just indexed.

Re: [RBW] Cranky Crank VO Replacement
Yes, I remember reading that article, as ell as this from Peter White's web page: The quickest shifting on triple chainring cranks with Shimano's STI shifters can be had only with matched sets of chainrings. For example, the nine speed Shimano Ultegra Triple crankset 6503 comes with three matched rings; 52 - 42 - 30 teeth, and the later ten speed Ultegra 6603 comes with 52 - 39 - 30. The alignment of the teeth and the positions of the steel pins that lift the chain from smaller to larger rings are carefully positioned to make up-shifts as quick and smooth as possible, even under considerable pedaling forces. With a few exceptions, TA chainrings are designed to be used with many different adjacent rings. The TA rings have pins for lifting the chain, but since you can choose from many chainring combinations, the three rings you end up with won't be matched for tooth position or pin position. That makes the shift a bit slower than if you use Shimano's matched chainring sets. But STI shifting still works. You just can't pedal as hard while shifting as you can with Shimano's rings and still get a smooth shift. Don't worry though, they still shift very well. This is only an issue with triple cranksets. Then there's experience. I have two cranks with ramps and pins. They both shift phenomenally well. The first one I ever bought was the White Ind. VBC. I run a 44/30 on my ram. The second one was for the tandem, which had a lot of shifting issues until I made a number of changes, including buying TA rings for the outer and middle position (48/38). Both of these shift very well. What I gather from Jan, Peter, GP is that these ought to be a bit slower. Well they may be a bit slower than STI, I wouldn't know about that, but they are certainly no slower than unpinned rings. What I experience and appreciate is that neither of these ever struggle to connect and they never skid over the top. I can rely on them to be as easy as a rear shift. Of course, there is always the issue of teeth wear, which can be difficult to see. How many miles / years can you expect from a 7075 Al ring? I got out for 35 miles on the Ram today but plan a 15 mile ride on the Trek with it's questionable crank, so we shall soon know if it's toast or jam. Time to fire up the grill open a bottle of wine.

[RBW] Cranky Crank VO Replacement
I have a 10 year old Sugino crank, on which the left arm has now come loose twice. The first time I attributed it to my error in not tightening it down after reinstalling. I have never been ham fisted and now with some arthritis often overestimate how tight bolts are. The second time seems more problematic. I'm giving it one more try after getting out my 3/8 ratchet arm and leaning on it; but I am not optimistic. I've never been as enamored of this crank as GP and so have started looking for a replacement. The VO looks like a good value at $195. Cold forged, pinned rings. Does anyone here have experience with this crank? Michael -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Cranky Crank VO Replacement
I had the same problem with a Sugino XD600 on a long brevet with the left side crankarm. I replaced the left side crank arm along with the bottom bracket and torqued the crank arm down to 40 ft/lbs per specs. The left side arm only cost $23 and the BB was less than $20, so maybe this would be an option for you as well vs. a new crankset?

[RBW] Cranky Crank VO Replacement
The crank arm is probably toast. Once it starts loosening while riding, usually means the tapers started rounding out. Even with more torque, it'll eventually work its way out again.

I too dislike the hidden bolt on try XD 600. It seems like Sugino they made an aesthetic choice at the expense of creation of a technical problem Is there some other reason to have the crank arm leave the starfish at that orientation other than aesthetics? Also, have trouble getting the q factor narrow enough with the XD 600. Finally, I am sure this complaint is much less wide spread, but since I'm already on a roll you can't use bio-pace rings on the XD 600, or if it is possible it was too tricky (and inconvenient because of the hidden bolt) for me to figure out. Not sure if Grant meant a Riv designed crank, but that would be very interesting. -Aaron I'm done complaining now Young The Dalles, OR On Wednesday, June 18, 2014, Michael Hechmer mhech...@gmail.com wrote: I agree the XD 600 is a very reliable crank. But I live in a town with and ride a lot of dirt roads, and wet conditions (but much less since I retired and stopped commuting), so I have to take the crank apart a couple of times a year to throughly clean the middle and inner ring. At those times I end up cussing the hidden bolt and loose spacers. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.
