Static Sag?

[garth]

I always thought it was roughly supposed to be 25mm.

Read PB's guide to setting up a zx9r https://postimage.org/image/6jwehuhvo/ and it lists 5mm.

Is that not a ridiculously tiny amount?!

They've got the front at 30mm, just the rear at 5mm. Are they measuring right from the shock, rather than spindle to seat?

Hi

My guess would be a typo.

Also possible that they mean 5mm with just the bikes weight, with adding a rider making it something sensible.

But could just be that the rear spring is stupidly stiff, and to get more than a tiny amount of sag you land up with the preload pretty much non existent.

All the best

Didn't think of that.

I guess 5mm at the shock would be alot more if measured on the subframe!

I thought it depended on where you rode etc. On a track that's as smooth as a snooker table you're not going to want or need much sag, but in real world riding conditions 5mm is piss all.

when setting up downhill mountain bikes no idea if its the same i doubt it but should be 1 third or the travel but that would be sloppy id have though for the road.

Depends if they mean static sag or rider sag. Rider sag is measured with the rider sat on the bike, and should be 1/3rd of the suspension travel.

No ifs, no buts, no maybes. The 5mm of static sag might be taking into account a fat rider for all you know.
