Identical to richmtb. Checked after a month as was feeling grindy and FULL of crud and rust. Theres basically zero sealing bar the rubber ring that sits around the Crown race (which is pants anyway).
Given that our other bike has a Hope which has been going for 12 months under identical conditions doesn’t bode well.
Regards stems, FSA do a 35mm version, or the NC17 Slick Stick
Slickstick
offers a similarr stack height, but a single bolt clamp design so can run the stem slightly short (a hope hed doctor allows for more clamping force). Bit heavy though.
Lastly if you can live with a very short stem the Spank Spike is the lowest stem I’ve found
Spike
I eventually gave up and replaced the CSU so have both the above stems if your interested in buying ?
