Bos Deville 2014 User manual - Manual (Page 6)

Tuning tips :
When it comes down to hydraulic setting there is no such thing as a magical formula, many factors have to be taken
into account (bike balance, spring rate, geometry of the bike…).Having said, that you can draw conclusions from
what follows :
- Excessive diving of the bike upon braking : harden the LS compression.
- Often bottom out: harden the HS compression.
- Feeling harsh on roots or square edges : soften HS compression
- Uncomfortable, arms pain : soften rebound.
- The forks don’t spring back and stay low after succession of bumps : soften rebound.
- Front too high (in dynamic situation) : harden the rebound.
Whenever you are far from the standard settings (factory settings) It’s always better to consider what influences the
performance of the forks. Proceed step by step, one setting at a time by hardening or softening few click each time.
If you ever get lost while you are setting up the forks, always go back to its original settings.

3.1. Cleaning your forks
It is compulsory to clean your forks every time you use them, without waiting !
Nothing’s worse for your fork’s seals than dry mud.
It is very simple to clean your forks : wipe off the stanchion with a clean rag and then slightly lube the stanchion
(with silicon based product). Using of degreaser is totally forbidden.
On the same note, do not power wash the forks! It will only push the mud inside the forks and get it stuck
between the stanchion and the seals.
Cleaning Oil service Full service
Recreational use After each ride 1 once a year Every 2 years
Racing use After each ride twice a year 1 once a year
3.2 Changing oil
An oil change with the Deville fork consists in changing the oil bath in each leg. Keep highly attention about the
correct oil level, in both leg (cartridge and spring).
Low speed compression : 15 clicks from the fully tighten position.
High speed compression: 15 clicks from the fully tighten position.
Rebound : 15 clicks from the fully tighten position.
Compression : ouvrir de 8 clics depuis position fermée à fond
Détente : ouvrir de 16 clics depuis position fermée à fond Low speed compression : 10 clicks from the fully tighten position.
High speed compression: 18 clicks from the fully tighten position.
Rebound : 14 clicks from the fully tighten position.
3. MAINTENANCE
The oil service and full service must be performed by a BOS approved center. The BOS approved centers are
the only able to identify and appraise a damaged or worn part, especially in case of shock or wear on structural
elements such as the legs, the stanchions and the crowns.
