Rake on your bike.

jimi84

So..
ive talked to a few full sus owners and watched numerous videos on full sus set up and quite a lot of the set up the rear sus so the back of the bike sits lower than the front (rake)
I was wondering if anyone has come across this on a hard tail? especially now with 650b and 29ers if you sling a larger wheel upfont.
I do see drawbacks cost being the main one as youll need wheel, tyre,fork to make this happen but, i just wondered if anyone has seen it, done it, heard of it?.

I don't think so. The only way to lower the back end would be to install a shorter shock, or run huge amounts of sag. Both of which would be silly.

There is a tendency on new bikes to have lower BBs, short chainstays and a longer cockpit, with a slacker front end, but that's part of the design, nothing to do with setting up the suspension.
As for odd wheels, Google 69er (probably not from your work computer). People have been doing it for years. It's a bit of a rubbish idea.

69ers usually use rigid forks with no suspension correction so the front end stays at about the same height.

People have been fitting circa 20mm longer forks to slacken bikes out a bit for years.

I have a shorter shock on the rear of mine, it works fine as it was designed to run 100 or 120mm travel so I've used the 100 slot with the shorter shock so at full bump the wheel is in the same place as it would be at full bump in 120mm travel mode, it dropped the BB and slackened the head angle so the numbers were pretty much the same as an Anthem, so hardly radical.

Not quite the same as "set up the rear sus so the back of the bike sits lower than the front" though.

Trek's 69er was designed with suspension forks.

Although as a SS with DUC forks it was just stupid.

Specialized did a Demo 8 DH rig with 24" rear wheel 26" front(46er?)...that too was a rubbish idea.

I'd say it was exactly that!

Er no. Whacking on a bigger front wheel is not the same as lowering the rear, although it may, or may not have a similar effect. The rear stays the same.

The Rookie

Erm, correct, but the bit quoted never mentions a bigger front wheel, and I did indeed setup the rear suspension to lower the rear.

OP was talking about changing a hardtail......

That was the Big Hit, not Demo. Other than poor tyre availability it wasn't too bad. Rear wheels were bomb proof. Bit of a tendency to hang up on rocks but you'd never break a rear wheel no matter how badly you cased a jump.

Amazing, I read that as well, I still fail to see any thing wrong in my responding to that where he started with how FS bikes are modified expekianing I'd done the same, perhaps you can explain how that was wrong?

OP seems to have lost interest anyway...
