Chain Length Either Too Tight or Too Loose
Hi, bit of a newbie here. So i've not had a MTB in a long time and i got a really good deal on one of these http://www.halfords.com/cycling/bikes/mountain-bikes/carrera-banshee-x-full-suspension-mountain-bike-large-19#tab2 i'm loving it apart from the gears. When i'm on the 2 largest cogs the chain is really tight (there's no slack whatsoever), so i put an extra link in which fixed it but then when i go onto the 2 smallest cogs the chain just droops on to the frame. Any ideas where i'm going wrong?
