I would love a proper sequential shifter.
But to me this solution doesnt look that well engineered
Sure I can see why people could be attracted by a bulk of machined aluminium, but the shift action looks clunky with quite a lot of play. It looks more like an afterthought than something thats designed from the ground up (Obviously its exactly that, a bolt on solution).
I have no idea what something like this is going to cost (expensive I guess), but I would save op for a proper solution like a quaife sequential; that seems to shift more like a proper motorsport sequential. It basically works the same as a motorcycle gearbox (drumshifter for each fork).
And you can of course spec it the way you want in terms of ratio's and gear types etc (note straight cut gears in the video below for example)

Or a Drenth sequential but those things are completely unaffordable.
edit, I found the presale price on this bremer shifter and its $2.4k. After shipping, vat etc, thats about £2.4k, so not that expensive I guess (a quaife sequential is about 3 times that)
