Spacers below stem

[Hairy]

Stem is 90mm with a 6degree rise,wanna be slightly more behind the front axle seat can not move back on the rails anymore.

bar width ?

bar width ?

740mm

[Bizkit031]

Was on a 685mm

then a shorter stem or a larger frame bike would be your solution ... is your setpost in-line or laidback ... as a temp measure you could use a LB post (assuming you currently have a IL post) to get you further back.

 

Just be cautious though, you want your knee to still be over your axel or damned close to it when you are seated / clipped in and the cranks are horizontal

Welcome to Wednesday math class.

 

So you want to calculate by how much you would need to lift your stem, to shorten it by say 10mm. Lets take your head angle as 73degrees (most common) and your stem as a 0degree (easiest).

 

so using this you will get the following:

 

Sin17 = 10/x

or x = 10/sin17

= +-35mm

 

This would screw up any setup done.

 

(please correct my math if I have made a mistake, brain is rusty)

It's a dropper post no LB

Handling was so so with the shorter bars,much better with the longer ones,I am just curious to see if I get further behind the front axle what would it do to the handling.

Surely (using this method of adjusting the stem height) if you want move the bars towards being behind the front axle you would need to raise the stem, not lower it?

 

ideally you should use a shorter stem

It will transform it. Get rid of that long ass stem and put a 60mm / 70mm on there, and watch your bike do amazing things you never thought possible.

Does it make a difference if it is a 29er or is the wheel size not too much of an issue

Yes. Stems are very much wheelsize dependant. For a 29er, you must take the stem length on a sixer and multiply it by 11ty billion to get your desired stem length, in 29er compatible format.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Just in case you DIDN'T realise, that was sarcasm. And no. Wheelsize has no bearing on stem size.

Yea gather as much,maybe I must try a 70mm and go from there,thanks.

Going from 685mm to 740mm bars will take some time to adjust to, but stick to it & DON"T cut them down!

 

740mm is a very good 'wide' bar length.

Once you become used to what the wide bar does you might feel the need some time soon to try an even wider bars (depending on your length)

 

By going 55mm wider on bars (27.5mm each side) I'd say a 20mm shorter stem would be perfect for what you want to achieve.

Get your handlebars as low as possible, this adds weight/grip to the front wheel.

That's fine if you a climber,I'm more of the Enduro type.

How tall are you and what size bike are you riding, you maybe an in between size ie: could be riding a large in a compact style or an xl in a more relaxed style, what you are saying sounds like you need to go up a size.

I had similar problems particularly with lifting on the front wheel my setup was almost identical. I tried everything you are talking about, I went up a size , increased bar width 650 to 720 and reduced stem length 110 to 90 and the bike rides perfectly no lifting and 1000% better control and much improved technical capability.
