Guest Big H Posted February 9, 2009 Posted February 9, 2009 Al square taper, Octalink and Isis bottombrackets must be torqued to the manuafcturers specification. If not the will work themselves loose and damage the crank and in worst case scenarios come off. How does a crank just come off without the cyclists feeling there is play or something amiss....... and after 39km?????, they were most likely not even tightened by the bike shop before they went out!!!!!

Edition 507 Posted February 9, 2009 Posted February 9, 2009 FSA.....common! Mine also came loose constantly!! Really annoying. My LBS confirmed there is a problem with the FSA bolts, but apparently there are different bolts that can be used to cure the problem.

It happend to a very experienced cyclist and I am sure she would have noticed if the crank was loose from the start of the race.
Pixie Posted February 9, 2009 Author Posted February 9, 2009 Yes, she is an extremely experienced cyclist. There was a lot of talk that Cannondale Holloway do come loose, but I can find no literature to support that statement. Thanx guys for all the feedback, much appreciated....
Guest Big H Posted February 9, 2009 Posted February 9, 2009 Doesn the Cannondale Hollowgram cranks have external bearings with a solid axle on the chainring side and a loose crankarm that fits onto splines or is it an internal BB like the older types that fits with a crank bolt?????
Pixie Posted February 9, 2009 Author Posted February 9, 2009 It comes with a bolt, the bike shop replaced it a few days after the crash.

No. Not external bearings.Bearings are INSIDE the frame. Axle is SEPERATE from the cranks. "Older types" like Oom says....Crank bolts both sides.
supertorro Posted February 9, 2009 Posted February 9, 2009 Sorry guys' date=' the one person had FSA cranks, and the other Cannondale Hellogram (hope spelling is correct), the cannondale cranks were fitted on the Friday, and fell off 39km into the race on the Saturday, the rider ended up with a concussion, 2 vertebrae moved, the dr said she was very, very, lucky she did'nt brake her neck. [/quote'] WTF!! is it just me or is it not an exceptionally bad idea to do anything to your bike the day before the race?

Jy het darem 'n Supersize BB Cup...... jy moet net gaan seker maak jou bout sit nog aan jou se ly...... ek bedoel fiets!!!!!!!!
backup rider Posted February 12, 2009 Posted February 12, 2009 Hi Pixie. Dunno why you even asked the question here as you have the answer to everything else except what you actually asked. The rider must make contact with the manufacturers and maybe she can speak to them directly as I heard the same story you did probably from the same source. Just do not speak to the sales rep as that will give you even more waffle which you can do nothing with. I am just glad the rider in question is getting better again and at least moving around outside again. Myself and my old friend Backlash just realised how little we know about broken bikes and broken people that day. backup rider2009-02-12 07:38:21

Of course there is banter, this is the Internet. However, there are also some very clever and experienced people here and if you ask a question and support it with the right data, such as the type of crank, background circumstances etc, you'll arrive at the right answer. However, just saying "my car makes a funny noise, what could it be?" is sure to bring out stupid responses.
