Although the valve core is not removable, this is not an issue as the Hi Flow design means you can push tubeless sealant through the valve without it getting blocked at all; there's no need to carry a valve core remover or spare valve cores for when a typical Presta tubeless valve core gets bent or clogged up.

We recommend the mount be placed behind your hands whilst in riding position and angling the head unit for perfect viewing. but my bag is usually full of sandwhiches, a waterproof jacket, this is the UK after all, a cafe lock and most rides a GoPro because of the UK Gravel Collective YouTube channel so there’s not much room to stuff in the afore mentioned tube etc. However, the biggest change since then is the use of PBF 3D printing as a feasible production solution.However I also had a issue when after hitting a pothold the tyre shifted and wouldn't re seal, maybe the tyre pressure was too low, but I don't think this should happen in any case.

Have been using Milkit valves for a couple of years - mostly good but the plastic valve tube gets twisted/stuck often. You can either seat the tyre without sealant and then pump sealant through the valve, or seat the tyre with sealant in.In the real world the rider accounts for 60% of drag and the savings generated by wearing a aero helmet are soon lost if the rider needs to move their head to every time they view their computer.

With versatile mounting placement and its low weight (22g), it's a useful addition to the bike for carrying items. I tested their strapless top tube bag way back and found this to be a very convienient system for stopping floppy bag syndrome and portability but now they’ve transfered this technology to what most dyed in the wool cyclists would refer to as a saddle bag. It’s been used in wet, cold weather and in warmer temperatures during a lot of rocky and rough riding.The 76 Projects Hi Flow 'No Clog' tubeless valves are excellent, and a gamechanger in tubeless setups. Straight away the look of the mount was good and purposeful, made of sturdy plastic with a gloved hand friendly Velcro strap to hold everything in place, as movement and rattle would be a reason for me to not to want it on my bike. To be frank, it has taken us a while to get away from designing for injection moulding, and the inherent limiting parameters such as draft, wall thickness, core access, and so on.
