This thread is to explain my experience from lowering my 2009 570 for ice riding, or any relatively high speed sliding activity (compared to trails riding, that is).
I do one or more winter projects just to have some fun, this year I focused on lowering my 570 as its a dedicated track bike for ice and gravel races. Most of the bikes attending these type of races are lowered to some extent, and I thought Id try doing that to my bike as well.
In the gravel series a friend of mine bought a new bike for the last race and told me I could try his old bike out that was lowered quite a bit. It felt well planted and stable in a completely new (to me) way, gave massive confidence riding it.
So to the berg, all I needed help with was fabricating a longer nylon distance to keep the fork down 70mm and cutting the spring to fit and make it flat at the end, to retain spring preload. Fork is easy to figure out the distance as its 1:1, for the rear it was more complicated for me, I let the rear alone until the forks arrived and then just unwound the the rear spring tension until I got what I wanted, then measured the spring length diff and made a distance equal to that. Method worked fine.
There is another thread I started regarding if you will need changing triple clamp offset for this, the answer is NO!
Ive just had a few rides on the bike since the change, and its very different. Obvious is that its closer to the ice, but its just positive.
Braking stability/feel is the one that I had no idea would improve this much, absolutely stellar. General stability in corners is much improved as well. Bike wont move around anywhere near as much as before.
Quite like it
