To you negligible. To me irrelevant as none of my bikes are left in public places. lockout skewers is viable alternative albeit with the leftie not needing to remove is a pro as the person asked. Agree proprietry hub is a con.
That has to be said is an negligible advantage compared to the disadvantage of having a proprietary front hub. You can use locknut skewers to achieve the same result. I like the look of the lefty design. But from a practical standpoint it's a waste of space.
most others covered - one that seems missed is the ability to change the front tyre/inner tube without taking wheel off - on a commuter bike, possibly stored with access to public it means you could use a fixed nut and only have to focus on securing rear and frame.
Ah, now you've misunderstood me and put an awful lot of words in my mouth. I don't claim to know more about making frames than that company. I do however reserve the right to criticise their graph for being generic nonsense because it provides no meaningful values. As you say it relates to their frames, not those of others so I wouldn't say X was better than Y just because their version of X was better than Y. Would I consider a generic Fuji Ti frame better than a Mason Alloy one? No way. Would I consider a Sarto carbon frame brittle compared to a cheapo steel frame, again nope. As I said before, read the trustpilot reviews. 1* given because Triton charged more for postage than the stamps on the parcel added up to. 1* given because an item said to be in stock took a week to arrive because they'd accidentally said they had an XL when in was an L ......and countless other petty gripes. So yeah, useless. Please don't say that I won't listen to facts, I bloody love facts and details and all the minutiae that go into bike design. Hence my dislike of that bloody pseudoscientific graph you like posting up when you throw generalisations all over the place! ;)
