need to borrow a tool to remove my mountain bike rear cassette or some one to do it for me

rear casette, doesn't that just use an allen key???

never had to do anything with mine (had my rims changed to halo's but paid a man to do it for me) so can't be sure sorry

I should have one fella , I got most things for a bike , it's just a splined. Nut really . Give me a pm .
