So the reason a dog leg works without the need of a clutch is due to the large spacing between teeth allowing the gears to mesh quickly without issue?
"Dog leg" refers to the H gate, as found on some old M BMW's, where 1st was a dog leg...ie not on the main H
Dog engagement is different.
And yes, a synchro box will only engage gear when all synchro teeth are in alignment, which requires the baulk rings to adequately slow the gears to match that of the slider/shaft.
With a dog setup because there is a large window of opportunity to engage it can happen more easily, far less smoothly but pretty much unhindered even if gears/shaft speeds are not matched
Great for racing....not always so nice on the road. A lot can depend on the driver for normal road use as to how tolerable it can be.
