Yes, but bikesarefun said Australian Standard, not new guidelines.
Are the IMBA Au guidelines relevant now that there is no longer an IMBA Au?
Bloody good question and could be a curly one too. Our LM has already said IMBA or alternate QPWS standards. While that generally means don't cut or expose roots unless unavoidable, don't chop certain trees or build dirt up around an entire tree base, if we push our luck it may mean 1 way only trail, no bridges and no TTF other than what the hill provides. We cannot lose their support or confidence.
I am going to throw out the one thing that has not come up in the thread: what makes a trail flow? It's not whether it is called a flow trail, it's not about speed or technicality, it is not about trail gradient or isolation. It is about whether the trail allows riders to flow while riding it. The key is good sightlines, avoiding inappropriate, hard braking into unpredictable corners, allowing leaning without slamming your body into trees etc. Some like trails that avoid all this (as previously detailed), but they do not suit the general riding population and they do not survive the test of time - either deserted or changed by others.
Summary:
> "Flow Trail" is a very small subset of flowing trail
> Our historical trails are not the result of foot and animal travel between villages, otherwise inaccessible. They have not been used by small numbers over hundreds (or thousands) of years and had the chance to become truly established
> Modern trail design is not evil and anti-MTB and makes up a very small percentage of all MTB trail - 5% was mentioned and that is accurate where I ride.
> This sort of trail design is demanded by land managers.
> 5 people per day do not ride per location anymore and trails cannot be made like they once were, although they can be maintained in their old style if riders are prepared to help
> Riders who whine and ride and don't dig have no say (both morally and actually)
> Riding DH trails on AM bikes is a reflection of the bike more than the trail or rider. Go grab a rigid, 120mm stem, 580mm bars, 71 degree HA bike from the 80's or 90's and give it a crack!
> Flow in a trail means you have the chance to see, predict and better ride what is coming next, up or down, fast or slow. If you cannot do that for example on the edge of a cliff, then you do not have challenging trail, just dangerous trail
> If you build trail designed so as to exclude 95%+ of riders, then it should be a legal black or double black line. If you do it illegally on land where legal trail work is supported by the land manager, you are being selfish and counter-productive
> Public access MTB trail is not built for the builder anymore. What I build does not belong to me and is not necessarily my favourite style of trail. It is made for the general riding public. The most reliable index of acceptable trail is the chance to have fun riding. If all you want to do is struggle and suffer and prove yourself, then you have a psychological problem and not a trail access problem
> Every trail system should have variety and no one style of trail is best
One more thing - 29ers have changed what people want to ride more than any other influence. The masses bought bikes designed to turn slower, hold speed better and make everything easier. Now it's the fault of trail builders they want that sort of trail??? Want it harder - get a 26 inch or 24 incher.
BTW: today will be a riding day. On all sorts of trail from flow to exposed tech. MTB is good
