Looks awesome, I wonder where they will all crack...

Lars - sure, all true. But let's break it down a little. Development time? Come on, look at it, it's a bit of metal with some slots in it and a couple of pieces of moulded plastic - the concept of which has already been developed by any number of equivalents out there. Material costs, well see previous sentence. Aluminium & plastic are not premium materials and there's not even much of it there anyway! Machine costs? You think MRP don't already have CNC machines or can outsource some plastic moulding? Yes labour and fixed costs and all that crap have a part to play. Well guess what, all that applys to the likes of superstar and their equivalent is well under half the RRP on this. But anyway, the point you made at the end is spot on - this is priced as a premium product (even if it isn't really) and the reason it's $135 is because that's round about what E13 & Straitline charge. And we're the mugs who buy into all this bullshit rather than just buying a superstar one!

Pretty sure the argument is presta hold air better because of what Mike says about the air holding the valve shut. But again, makes absolutely no difference in the real world - probably because we're all using low pressures anyway compared to say road bikes. Only advantage to drilling your rim is you can put either tube type in, just good luck converting to tubeless later on!

^lol hope you are no older than 11 to be saying shite like that
