I kind of despise threads like these. Mainly from new forum members whose seemingly only purpose of creating an account is to ask these type of questions. But here we are...
Currently I am reviewing the latest Ventum NS1 in size 58/L and it is freaking fantastic. Moving up a frame size has been a revelation in terms of comfort, stability, weight distribution, and most importantly not needing a 140mm length stem.
However, not every brand has the exact stack and standover height requirements I need in a larger size. Most are just terribly too high for my needs.
While the NS1 isn't an open mold design, it's clear in the finer details that Ventum is using a Chinese factory. In fact, I was able to swap out the provided 7x9 saddle clamp in favor of a 7x7 clamp from my TanTan x38 road bike.
Both Ventum and Rose Bikes have a geometry in a size large that works for me. Curious to know which factory are making their frames.
