All Mountain Project

Recommended Posts

Here is the bike I have been building for 'All Mountain' riding, whatever the f**k that is :giggle: I thought all mountain bikes were for riding on mountains.

Feel free to define all mountain for me.

All I have left to do is sort some grips and bar ends out and it will be win (I hope)

I'll post the spec for anyone that is interested when its all done and put some better pics up.

Looks tidy :)

Get some better pictures when you have finished! Those Giants are so nice!

Seats are a personal thing really but I have run the SDG Bel Air that came on my bike for years with no major complaints. I know my LBS have a load of test saddles that they loan out to customers so it might be worth trying that if you are friendly with any shops near you.

Get that front brake hose routed correctly along the inside of the fork leg (Y)

Yes your quite correct sir! Problem is I havn't had a bike that I will be peddling for hours for many years.

I'll chuck picture of my last 'All mountain' bike (from before the term all mountain was dreamed up by the marketing devils) in this thread tomorrow.

The saddle I had on my last XC bike was very nice bu also very expensive, over a hundred bucks I seem to remember.

Aim for about 30% sag front and rear in full riding kit. Many people I Know run the rear's too soft meaning they "wallow" into compressions and corners giving a very unpredictable ride. Your in a good situation running air forks and shock, as adjusting this is easy with a shock pump. Are you running duel air, or just air sprung sektors?

Rebound wise, its very much personal opinion. I don't like too much rebound damping, so i get the most bump absorption out of the fork (too much will result in the fork / rear end, skipping over bumps, and a sluggish feeling bike) Yet too little damping will result in a pogo stick effect. Its a fine line but one you will have to generally find yourself. Start in the middle of adjustment and work from there.

Also: Too much rebound damping on the rear will also cause the bike to wallow or bog down in corners. Where as you would idealy want the bike to compress if needed, but mainly stay pert through the turn.

Hope that helps

What settings have you got on the forks? I'll assume you have compression + rebound + floodgate.

Turn compression/rebound off first of all.

If they're dual air, add enough air to get 30% ish sag

If they've got both +ve and -ve air, do the positive air first (aim for 25% sag) then put the same amount in the negative side (this will almost certainly give you 30% ish sag afterwards)

Set the rebound, this is mostly personal preference but depends a bit on the terrain. I like my forks quite fast.

This is fine for the basic setup, for years I left the compression damping fully off with my Pikes.

The compression / floodgate is the hardest bit to set up properly, and if you read the forums there are a million differing comments. What I like to do is to have a reasonable amount of compression (halfway to 2/3rds ON) but set the floodgate so the forks move easily, maybe 4-5 clicks from full anti-clockwise. This way you can avoid bobbing but the forks will start moving on even fairly small bumps.
