So I recently installed a [lightly used, purchased on Ebay] S-Works crankset on my 2015 Specialized Tarmac. After about three weeks of riding, I realized that there was a lot of play in the cranks, as in there was a lot of side to side movement. To remove play from this crankset, you tighten the three tiny, 1.5mm Allen bolts in the cone spacer against the frame on the non-drive side. All three had come very loose so I tightened them. After my next ride, I checked these bolts and all three had loosened again and there was play in the crankset again. There is Loctite on these bolts, so I don’t understand why they are coming loose like this, after just a two hour ride. Everything was installed and torqued per the instruction manual so that shouldn’t be the issue. Anyone have any experience with this and/or suggestions on how to fix the issue? I’ll admit, the Loctite perhaps is old and could use refreshing but it still seems wrong that just a two hour ride could significantly loosen the bolts. Thanks!
