Rated 5 out of 5 by Expensive but quality The bolts are undoubtedly expensive but have a very high quality feel to them and a nice finish. I'd previously struggled greatly in getting other chainring bolts tight enough (using all the right tools!), these were much better. They had loads of bite and were a perfect fit. I still used some thread lock but reckon they had so much bite that this was actually overkill. I used the bolts on my FSA Vero compact chainset (52/34, 9/10-speed), which had started creaking, they fit perfectly. In fact, they seemed to be a much better fit (length wise) than the original bolts! The female part of the bolt was slightly deeper than either of the 2 variety of bolts that I took off. This meant that the outer chainring sat on the female part of the bolts (as I would expect), what is odd is that the ones I took off, being shorter, clearly didn’t allow this (seemingly crucial bit of engineering!). I measured the female parts to have a depth of approx 8mm. I also made another discovery!! The shimano chain bolt tool, which I had previously dismissed as being absolutely useless, was an absolute perfect fit for the shimano bolts!! This made fitting sooo much easier. I also discovered (!) that my inner 34-tooth chainring was bevelled (allowing the bolts to be countersunk) but only when the chainring was fitted “the wrong way around”! Possibly I incorrectly fitted it previously and they should always have been countersunk?!? Anyway, this time I fitted the bolts so that they were countersunk on the inner ring (no chain alignment issues afterwards). After assembly and road test everything felt very secure, and best of all, no creaking! 31 December 2013
