Flaanimal compatibility with mechanical post mount brakes
We expect to have sliders back in stock by mid March. This assumes our machine shop completes our order on time.
Seatpost Clamp size
Yes that will work.
Disk diameter at the front
160mm is the maximum stated diameter for the frame / fork.
Setup question using Paul Klampers and 160mm rotors
Our bikes adhere to the flat mount design standard which specifies 140mm native, and 160mm with the use of adapters / mounting plates.
Triple Cage Mounts in the future?
We don’t currently have any plans for 3 bosses on the fork legs. Spork already has class leading cargo carrying capabilities, and the inner and outer bosses actually add up to 4 mounts per leg, not 3. When loading the fork with loads heavier than typical water bottles a 20-25mm bolt is used to anchor the loads to both bosses instead of just the outer bosses.
We know that many in the industry use three bosses and that is the prevailing standard, but we’re stubborn on this one and aren’t a company that looks to the right or the left for inspiration. We’re only interested in what works, and the boss system on our forks have been incredibly reliable and useful in every type of riding and bikepacking condition that we and our customers throw at the fork. Our boss failure rate is almost incalculably low, and failures have never occured due to loads on the bosses, it is always from people trying to remove siezed or stuck bolts.
For people who wish to run 3 bolt mounting accessories we simly instruct them to use 2 of the 3 bolts on the accessory.
For those wishing to maximize the load carrying potential of the fork we recommend the Wolf Tooth b-rad system and the mount splitters which allow you to reliably mount double the cargo capacity per fork leg.
Dropper post travel for Flaanimal
This depends entirely on how aggressive you will ride the bike. I tend to only recommend droppers to people who will trial ride their drop bar bike. For normal gravel there is no real advantage.
Most “gravel” droppers are only 40-50mm which isn’t really a lot but does help get the saddle out of the way.
PNW makes 90mm and 120mm and I’ve run both with success, but I don’t think most people would use 120mm very often.
On my bike I would probably go for something around 90mm.
