rondo101 – weird, I was about to post the same thread (and I’m in Bristol too, and store bikes in my house….).
The ones that came with my Reverb seem OK, having had 2.5wt oil in them. And I’ve reused them with 3wt oil to bleed a Charger Damper a few times.
For fork lowers, you dont need to inject with any pressure, so I just use a big syringe with the seal removed. Or multiple injections with a small 5mm syringe as suggested above.
And I switched to Shimano brakes on all our bikes recently, removing the DOT / syringe problem.
Where’s your road trip? I recently spent a lot of time in the US without bleed kits and oil and had various Pike issues, I found most LBS’s very helpful (but I know it feels good to be self sufficient).
