Shimano 1P417000 – Left Crank Holding Cap Fc-6800

When I set up my 105 crankset, I didn't realize that my crank arm wasn't on all the way. This caused the crank cap to shear and break. Luckily, this one is exactly the same as my old one, so it worked perfectly as a replacement. The only complaint I have is that you need a specialty tool to install it if you don't want to risk damaging it. Other than that, it's great.

I bought a used 12 speed Ultegra crankset that was missing this part. Perfect replacement that was easily installed with the Shimano tool. Hand tighten only.

This is a simple item but my cap was missing from my crankset kit. You set the bottom bracket bearing preload by holding the crank arm against the BB, but this is the precise way to set BB preload and it keeps the dust out. It fit perfectly on my Shimano Deore crankset, left side.

Exactly as described. Nothing more, nothing less

This is a critical part of your bike and if it comes off you have a long walk home. Mine came off twice resulting in a 10 mile walk home. First time it came off the pedal detached long walk home. I bought the aluminum one here on AMAZON a year later while cycling that one came long walk home. Heres what you should know both were on tight but I ride a lot and the vibrations eventually caused them to loosen so you should buy the tool and check and tighten regularly to avoid this situation. Buy the one recommended for you bike because its aluminum don't mean its better this plastic one thread are longer and fits snugger than aluminum and handles vibrations better get a backup and the tool and keep with you when cycling . This is the best fit product the aluminum threading was shorter .

if you cross thread your plastic bottom bracket cap/ fixing bolt, this will replace it on the latest 11S Ultegra cranks.

Stays put and not falling out

Needed to replace the stripped stock 105 fixing bold. This one has a shorter thread but works well. Tools attach well to it and it handles much better than plastic crap.

compatible therefore it is good
