ultegra octalink: tick Tick TICK TICK TICK!
when i built up my last bike, i needed a triple. stop
snickering. i just needed a triple, that's all. and campy had two alternatives: ugly and expensive, so i went with shimano for the first time in around a decade and a half. at first, all was wonderful, but within six months (let's say 3,000 miles or so) the right crankarm started ticking against the octalink spindle. so i did the kind of things i normally would do: pull it off, clean it, rotate it 90 (or in this case) 45 degrees, etc. and i still came out with TICK TICK TICK everytime my pedals came round. and NO, it isn't the pedals, and it isn't the cleat. finally, i'd just had it and (1) schmeered a little grease on the spindle, despite years of experience screaming in my head to NOT DO THAT. i also (2) bought a record triple 9 at a super bargain price once everybody decided that 9 speed was so last week. now, before i put the record on i thought i'd check and see if this is a common complaint with ultegra octalink, and if it's at all curable without resorting to method (1) above every couple of months. |

It isn't the bearings, is it?

The Octalink service instructions recommend grease. http://www.shimano-europe.com/cyclin..._pdf/16T0B.pdf |

Very common. Grease the livin' bejesus out of those splines! Octolink
is an interference fit, not a press fit. The splines on the crank and the spindle bottom out onto eachother. Lots-o-grease will keep it quiet. NEVER grease the tapers on a square spindle, but grease splines to your hearts content. --Jim |

I've been greasing the tapers of cranks for 25 years, never had a problem as a result. In order for the retaining bolt to be properly torqued, the taper, the bolt threads and the washer should be greased. Friction will cause a false reading. |

may have said: Very common. Grease the livin' bejesus out of those splines! Octolink is an interference fit, not a press fit. The splines on the crank and the spindle bottom out onto eachother. Lots-o-grease will keep it quiet. NEVER grease the tapers on a square spindle, but grease splines to your hearts content. Some crank and BB installation instructions I've had specifically recommended greasing the surfaces. YMMV; I don't think it makes a difference *provided* that the retaining bolt is torqued adequately, and IMLE this is not always the same as "torqued to the manufacturer's specifications." -- My email address is antispammed; pull WEEDS if replying via e-mail.

H guy- when i built up my last bike, i needed a triple. stop
snickering. i just needed a triple, that's all. and campy had two alternatives: ugly and expensive, BRBR Hmmm, Centaur looks like Record and is less expensive than Ultegra. finally, i'd just had it and (1) schmeered a little grease on the spindle, despite years of experience screaming in my head to NOT DO THAT. BRBR maybe read the literature that comes with the crank. MUST grease the octalink spindle threads. NOT the Campagnolo suqare taper spindle. Grease it, align the splines w/o the little cap on and tighten it until IT STOPS with a big 8mm allen wrench.

I have a Utelgra 9 sp tripple in my Litespeed. I've had some noise in the BB, cured with Teflon(r) tape. I do grease the splines, but I tend to grease everything as a matter of course. No other noises I've noticed. With all the broken crank threads lately, I'd take a really close look at that crank arm. Ken |
