Best "Downcountry" 120ish-mm Frame for Long Climbs and Rough Downhills

[RobinRLS]

The Workswell WCB-M-364 would be the best choice imo, a rear triangle pivot, 120mm rear and 130mm front, a 65.8° HA, and pretty light because it shares all the frame but the rear triangle with the 363 that is their new XC-bike.

I like that one too, I contacted Workswell in early march, but they couldn't tell me anything yet about the frame, so I guess it still takes some months till it's available.

Hi,

Why not use the FM1001? It can be built up with 120mm rear travel and 120/130mm Fork... Slightly heavier than the FM936 but not much 200g on a medium, unless you take the 936 Super Light then it's 360g

Cheers

That is true. I asked Carbonda if I could put a 130mm fork without dropping the BB height much and he said yes but then he suggested I could do a 10mm spacer bottom headset as well. Putting a 120mm fork may drop it too much? Need a good light weight fork. New for 2022 is the Ohlins RXF34 m.2 mountain bike fork which is interesting. There are a select other forks around the 1600 or 1700g weight. Not sure lighter ones in the 130/140mm travel range.

Hey,

i calculated a change in fork length. On FM1001 120mm the BB drop is 35mm (341mm height), which is still pretty high.
Transition spur 120mm is 336mm (40mm BB drop).
My Titanium softail (160mm fork) is 333mm height (43mm BB drop) and has no problem of pedal hit on the group. Kona ESD is 314mm for instance.

But the seat tube angle of FM1001 120mm will be very steep at 79°
If you climb ultra steep hills, it will be helpful, but if you also ride flat trails, it will be awful.



Why don't you build a custom titanium bike ?

better quality geo table :

Just to confirm…that calculation is based on 120mm shock and 120mm fork? If so, that’s not bad.

120mm shock = doesn't impact geo chart
120mm fork as written yes

well let me just say Winow FS030 is not recommended as durable.  Did this last night on a 2' drop at speed.
