complete beginner here..bought a monty 220 hydra a couple months ago...took my rear wheel off to grind today, and ama bit perplexed now that i am putting it back on...there are snail cams and chain tugs on it, i figured it would be no problem but when it came time to throw it all together im a bit confused.. when using snail cams AND chain tugs, do the cams stay on the inside of the frame? anyone have any good pics of their own snail cam/.chain tug setup?
