Hello! 
I'm restaurating a Sherpa 199B. The betor shock absorbers are completly damaged. So i have to look for new one. 
The length of the original betors are mounted on my bike is 345mm. 
I have found pretty shocks on web called BBS-competition. 
But they only available in 340mm or 360mm length. 
What do you think is better 340mm or 360mm? Dose the 360mm shocks fit the 199B? 
Have any classic-freaks experience with the BBS-competition? 
Thanks for your answer!
