I would just like to say that having had experience with try all, monty, tensile, acs and echo freewheels aswell as seing my friends canibalise virtually all other freewheels the only clear option for me is the echo. I had one of the first try-alls from tartys and it skipped frequently for about 8 months until one day it droped apart mid gap. I also had one of the first echo sl's from tartys and it didnt skip once throughout its 2 years of abuse until it one day ceased to engage. I have recently taken to a brand new black echo sl freewheel and it seems exactly the same, the only difference other than the colour is the 8 tab removal system. So stop wingeing if your breaking them it may be because you have a defective one it doesnt mean there all bad, if i had to replace the most important part of my drivetrain every 6months i really wouldnt care, its like a tenner every month! its cheaper than adopting an african anyway
