FSA Alloy Double Chainring Bolt Kit - Durable Bicycle Crankset Hardware for Road & Mountain Bikes - Perfect for Bike Maintenance & Upgrades

This is one of those reviews that was hard to measure . Two issues with the description . Yes I received 10 pieces like said above and paid for , but when I ask if there is 15 pieces based on some reviews I got an answer saying there is 15 pieces as stated in the below description , alittle misleading but not a major issue because I thought I was getting 10 . They are a quality item overall but there is a issue more relevant and important with the description . They are not cold forged steel but aluminum , basic test is they are not attracted to a magnet like the FSA bolts I was going to replace and the likely cause of some breaking issues that some have had . Although FSA states the torque on these bolts is 12 nm or 106 inch pounds but not sure if its for these aluminum bolts or the steel ones . The lazer etching is nice though ..chainring bolts are supposed to be an easy/no-frills item to buy and install. this was not.1. the white etching on the outside looks nice.2. the pack does come with a small L-shaped torx install tool, but I'd recommend another tool with a longer handle for leverage.3. the rear nut is a 6mm hex, not a torx, so if you're buying these with the intent of having them not slip due to using hex tools and you don't have a chainring nut wrench, i'd probably just get regular chainring bolts instead. installing these using a hex tool for the rear could slip as it did with my first/only install attempt because of the softer metal of the rear nut. If you plan on using a chainring nut wrench (i do not own one and did not try using one) you may have better luck than i did. i didn't feel like buying a special tool for installing these since I've never had any major problems with regular chainrings (my fault for trying something new and different...)4. DEAL BREAKER - the preinstalled thread locker was coated so thick and hard (I'm guessing the one I got was in inventory for a while) that 70Nm of torque that I applied could not make it budge and thus could not secure the chainrings to the spider (the chainring bolts' only purpose ). The rear slipped once under that load and it risked rounding the rear nut and that was enough for me to stop using these. I'm in the process of returning these and I ended up using an old set of sram chainring bolts i had laying around from an old crank.The description is incorrect. This is one set of 5 male end chainring bolts. With two back sets of female ends, one for double chainrings, and the other for triple chainrings I imagine as they're a bit longer. Not two complete sets of double chainring bolts which is what I was expecting to receive based on the title and description.I had one of these snap when torquing it down. Being a masher I generally push them to the high end of spec (100 or so on steel) to avoid creaking and groaning, but it snapped at about 75 (was going by Park Tools suggestion of 44-88 on aluminum bolts). I feared cranking down the rest to the high end and, as a masher, got the expected and irritating creaking noise on out-of-the-saddle efforts (greasing them was no help). So, back to steel for me which means no worries and a blissfully quiet drivetrain.Item not as described.There are 15 pieces in the package, but only 5 of the back piece, and 5 of each short and long length threaded pieces. Also, the back piece is fitted with an 8mm hex rather than the way its shown in the picture. I bought a chainring nut tool based on amazon's suggestion that i would need one... that was not the case.The item works, and was able to mount my parts correctly, however i bought extra tools i didn't need, and this works for only 5 holes rather than 10.So....these are honestly great. they're lightweight and look great. sadly if you ride with a lot of torque on your bike then do not get these. i managed to sheer four out of five of them in half while going up a hill during a race. needless to say i didnt finish the race lolBe careful not to over tighten and suggest greasing the contact points before torquing to
