Re: FM1001 / FM1156 - 135mm frame
Hello all, I'm very interested in this frame, but not sure what size would fit(M or L). I'm 175cm(5'9'') and have 82cm inseam. I find the STA of this frame is quite steep. That causes a relatively short top tube. I wonder if a medium will feel cramped or uncomfortable during some long and flat pedalling. But a large seems to be very long (it has 472mm reach and a 440mm seat tube length). My Current bike is a Giant Trance 2017 size M which has a 435mm reach, 73.5 degree of STA and 610mm top tube length. Should I go for a large? Or a medium of FM1002? I have 178cm and L feels nice to little short despite 55mm stem and 10mm offset seat post. With 44mm offset fork and 150mm travel the bike is surprisingly agile anywhere except uphill switchbacks. I don't dare longer stem in order not to cripple handling, which is very nice. I was and still tempted to try XL with short stem... But I cannot imagine myself on M. FM1001 has somewhat aggressive geo & long wheelbase even compared to contemporary trail bikes - if you are in, take L and short stem, if not, look elsewhere. Short offset fork probably helps agility and I don't feel any lack of stability at speed. January 03, 2023, 06:49:05 AM |

Re: FM1001 / FM1156 - 135mm frame
And this interesting https://www.detrailbikes.com/berg-155/ Looks like they put different rocker (Alu instead of carbon?) to squeeze more travel and increase progressivity of our topic. This is exactly what I want, may be not up to 155. Interesting approach instead of using FM1002... March 28, 2024, 10:22:30 AM |

Re: FM1001 / FM1156 - 135mm frame
As per my info, FM1001 has flat and quite "low" leverage curve. It needs air shock with a lot of progressivity (small positive chamber) and IMHO and above average low speed compression damping. Guys at Detrail are clearly aware -> they put small chamber & highly damped Ohlins TTX1 on their most expensive build. Also, for their "Berg" model they designed & created new rocker link and market its 30% progressivity (clearly a design objective to remedy problem of zero progressivity of the origianal).
