- Have I wrecked my cranks?
So, the time has come to replace the drive train on my hard tail, and today I took on the task of doing it myself.
I’ve hit a wall, though; on swapping my small and medium chain rings, I attempted to remove the crank arm with the extractor tool that came with my cheapo Bike Hand toolkit, but on tightening the puller, the threads were stripped from the crankarm shell.
I don’t think I need telling that I’ve ruined the cranks, so can I get away with one new arm or will I have to get the whole unit, bottom bracket and all?
This is the bike spec if it helps: Ghost SE 5000

It’s a PITA if the crank’s extractor thread has stripped, but a replacement isn’t ruinously expensive – certainly it’ll be cheaper to replace the crankset than it would be to source new chainrings when they wear out.
FWIW a quick squizz at Merlin Cycles will see you right and leave you change from £60 for a Deore crankset which will last you for years to come.Posted 4 years agosomafunkSubscriber
That’s a 9spd octalink crankset and BB, spend your money wisely and consider something like this shimano deore chainset & BB for £58 to replace it with, if you still run the original chain and rear cassette then i’d possibly consider changing them as well, £10 for a cassette and £9 for a chain.Posted 4 years agochipMember
I had the same crank on my hardtail.
Removed once to replace bb and twice more to remove bb for a clean and re grease.
Never had any problems removing the arms.
If it is knackered I would upgrade to a deore hollowtec or slx if your budget allows.Posted 4 years ago
And get your bike shop to do it as your bb shell may need facing .
