I rebuilt my Sherman Fireflys (TPC+ model) yesterday and I thought I'd post and share some info on them.
Currently the most up to date manuals for the shermans reccomend running 6mls of oil in each leg for the semi bath lube.
On the advice of my LBS I increased this to 10ml per leg.
I found a very noticable difference in the way the forks ramps up after adding oil. Before adding oil my forks would bottom more easily now the fork ramps up much harder and I havent noticed my fork bottom yet.
Anyway this is just a heads up to sherman owners to let you know you can play with your oil levels just like a marz fork to increase the bottoming resistance. I'm also really impressed with the seals in the shermans.
My fork was really clean inside even though I've been riding in the rain recently. Also I packed heaps of prep-M under the seals and and only a tiny ammount weeps from the seals unlike a boxxer which I've found leaves dirty grease rings on the stanchions until the grease runs out a day or so after a rebuild.
A while back I read a review of the slider plus and the owner complained that they were too linear and that reducing the SPV cambers volume helped but made the forks harsh. My guess is more oil in the semi bath will get the desired performance.
When I bought my sherman I was under the impression that the 6mls of oil in each fork leg was what kept the seals and bushings lubricated.
Its not, you still need prep-m there to properly lube the upper bushings and seals. This doesnt seem to be an issue though as my housemates sherman has been going strong without being touched since he bought it about a year back. Parking lot tests confirm that his fork is as smooth as mine which is freshly rebuilt (it bottoms out more easily though). I put this down to the seals on the sherman keeping the grease in place.
On a side note the mag lowers off the shermans are crazy light.
My thru axle lowers + 20mls of oil almost certainly weigh in less than dorado stanchions and the internals they contain.
I very much doubt the unsprung mass of a dorado is less than a slider.
Inside the shermans only the dampers shaft, the spring stacks shaft (alu) and oil contribute to unsprung mass.
Overall the shermans were very easy to work on just remember to turn the dampers shaft clockwise when removing the lowers (the manual says "remove" which implies anti clockwise). Turning anti clockwise snaps the end off the damper and could strip the threads in the lowers.
