my understanding is the internals are pretty similar but that KS use quad rings vs orings, might last a fair bit better. that could be utter b****cks, haven’t taken apart either. generally across the board, RS sealing is naff.
Lev is at least £100 more (DX £270 ish vs reverb currently £165 at Tredz, retail), they’ve gone up to nearly £500 for the top end Lev with carbon bits now 😮 don’t recommend importing, want the 2 year UK warranty.
I have a Lev (cheapest DX one, who needs a rotating saddle head? forward’ll do me.. i know it’s for cable orientation) and don’t regret that yet, nearly a year old no problems so far touch wood. 1 thing, remote is sticky first push of every ride i should check that out not sure if cable or inside. and yep, KS remote is neat.
