its me again, going on a topic spree here....  I just bought some oldskool xtr cranks off ebay (cos they were cheap)  I am wanting a 5 arm spider as it doesnt seem you can get 20 tooth cogs in 4 bolt, anyone know where I could get one? I saw a few on ebay a while back, but I have spent ages looking and cant find any   Is there even the chance of a one peice bash and spida (a la middleburn) that will fit? Leeson rings a bell, but I aint 100% on that.  Or even if someone knows where I can get a filthy ard guard, they rock!!  One last question, is 116mm the widest xtr bb you can get?  cheers  Mr C
