While cleaning the bikes at the end of today's ride, I checked Neroli's front forks. Either they are completely dry of oil, or she has managed to bend them or both.
Looks like I was a little harsh in my initial assessment. The forks weren't bent, they were full of water!
They have now been regreased and lubed and are working fine again (for the moment.....)
May be I was a bit hasty - "working fine". I can compress them, but only 40mm or so by putting all my weight on them. Neroli can hardly move them at all.
Unfortunately Saturday is looking wet and only froce 3/4 so not ideal for bike or sail. Nice forks though! The air/coil combination should overcome the slight stickiness that can affect some air forks. I must say I've struggled for a while now to decide whether to go with coil or air forks on my new bike. Currently I am favouring coil, but you may have the perfect solution!
