Hi there people, i Recently bought a frsh products tensioner so i put it on my bike and the chain was mega slak under full adjustment so i took a link out of the chain and now the chain wont even go round front and back cog, i have coust btw and i am running single speed one 19 tooth cog on rear and 22 tooth on the front on middleburns the only alternative i can think of is to go back to mech wich i dont want to, or i can could maybe go for smaller cogs Any good advice welcome
