HOME and how to join Forum Open Area General Scott topics Oleomatic (Dowty) Forks Re: Upside down forks

Rod Norris

The latest racing forks are known as USD (upside down forks). It is the stanchion that moves and the slider is static in the yokes. For many years modern (by comarison with most Scotts) have had their stanchions clamped in the forks but over the last 4 or 5 years they have been turned upside down as it reduces unsprung weight.
My previous comment was meant to show that these “great ideas” had been thought of and implemented many years ago, although not necessarily perfected. The “normal” forks where the stanchion is clamped in the yokes are easier to manufacture and seal whilst USD forks always have gravity fighting against them and wanting to leak. The Scott Oleomatic or modern USD fork is technically superior to the regular telescopic fork used generally for the past 40 or so years.
So the upside down comment is not a slur, but a compliment, sorry if I did not make that clear in my first posting.
