This will be better (from my own experiences) Same, cheaper, but out of stock From most of the reviews, this will be better again, but at more of a price. Won't need your hanger though, which is always nice Regarded by many as the best tensioner available Whip out as many links as possible, and run your mech properly (ie. as a real mech, both jockey wheels, normal routing etc) before buying one though, as you'll probably be fine. If not, stick on a tensioner, with the chain still as short as possible The non-sprung ones (DMR, Gusset, Onza) are fine, however if you land on your chain they will probably need to be repositioned (oh dear, 2 secs with an allen key!) Sprung ones (74Kingz, Rohloff) won't need this, as they are sprung () so will return to their original position Oh, and if you can find a tube that will hold helium, have fun
