I have a set of BOS Devilles & discovered that an Ohlins air shaft I had fits in the fork, however a new top cap is required as Ohlins one doesn’t fit. This would mean I would have a BOS fork with an air shaft that has a schrader valve at top & bottom of fork to tune the fork. So you think it’s worth going ahead with getting a new air cap machined as not cheap, however it gets cheaper the more they make if anyone else interested?
