2015 Suspension tweaks
on: May 31, 2015, 08:15:59 PM
Hi Folks,

I'm after a bit of advice on adjusting the front forks on the 2015 model.  I've tweaked up the rear with a couple of turns on the adjuster and it has really settled the rear down on poor surfaces  :001:

The front suspension has adjustment on both forks and it looks like you just adjust them anti-clockwise/clockwise with a screwdriver.  I thought before I tinkered I'd ask if anyone has done this and whether it's as simple as it looks?

Sorry though can't help you with this one.

Thanks Trevor, and apologies for showing off!  :002:

I know not many of the members are riding 2015 models as yet so advice is a bit thin on the ground, but I'll tinker anyway and maybe I can help someone else in due course  :001:

The only advice I can give you is, make a note of the standard bikes settings and adjust just one element at a time by 1 click or 1/4 of a turn, ride it and see what difference it makes before further adjustment. Keep going until the handling starts to get worse again and then back it off a bit to achieve perfection.  :046:

And start with the sag setting.

I've yet to mess with the front suspension, but in the rear shock I've tried some pre-load configurations, and currently what works for me (83Kgs +gear) is 4 clicks from the lowest/softest position, or 5 clicks if I take my wife (54Kgs) with me.

Our front suspension on the CR can be adjusted for the pre-load (hard/soft) and rebound (how fast does the suspension decompress). In my years of mountain biking, I've learned some rules of thumb for suspension and shock tunning, which I'll share:

The pre-load adjustment is used to define your SAG (the amount of suspension travel which is consumed/used only by your weight). Use a zip lace to measure it easily:



You should search for the recommend SAG for you, (in percentage of the suspension travel) according the use you have for the bike (offroad, road, bad roads, etc).

This is valid for front and rear suspension.

For the rebound tunning, it aims at maintaining the tyres on the ground. For the front suspension, rebound should be the maximum until it becomes too jumpy. For the rear shock, it's the opposite - the lowest posible setting but without saturating it (it should be able to decompress after one bump and be ready for the next one).

Again, the rebound tunning should take in consideration the type of terrain/road you target at. For example, on smoother roads you can tune less rebound on the rear and higher on the front. On offroad, the front would had less rebound and be back a bit more.

These are my findings while riding a mountain bike. My previous motorcyles didn't had any suspension tunning settings, so I can be dead wrong on this because what applies to a MTB doesn't apply to a motorcyle (my guess is it does, but still..)

Cheers,

Hello Chaps
I have just bought a new Crossrunner. I weigh 85kg inc bike gear and find it handles beautifully on the standard settings.  May just be lucky? I'd probably wind a couple of clicks on the rear before I go touring with luggage, but very happy with the standard setup for road riding.
Cheers

Hi Techno pleased you are enjoying your C.R.
I only want to fiddle with the front suspension because mine ( 2014) has non adjustable front forks  :010:
