I really didnt realise how bad either pair of my Shermans were until i got lyriks, yeah they are easy to service but they need to be; during a month in the alps mine must have been apart at least 10 times. I had two pairs with me an SPV evolve pair (truly awful, slowest damping ever) and a pair of £70ers off ebay that were a conventional shim stack which i removed two shims from to speed em up (slightly better).
Oh also if you buy a pair which still have working lockdown this is likely to break and spoil your day; mine did it on a day when we stayed local to Morzine but riding home down the worlds largest set of steps (pleney) with 20mm and horrendous banging was awful. The best thing to do with the lockdown is remove it (mine was well shagged by the time i got back to the apartment so i cut the ears of the mechanism off with a hacksaw).
