Skylark Posted July 13, 2015 Author Posted July 13, 2015 So the main purpose of a bars rise is to subtly alter the weighting of the riders body relative to the bike and all other things being the same its not going to have much affect on any thing else. In an ideal situation if you had enough steerer length would you want to go longer steerer/more stack height and less rise on the bars or shorter steerer/lower stack height and more rise on the bars?

More ability to get it as you need it. It's also what niner xc bikes struggle with, which is why you see all those flipped stems.

That's really what I want to know!

Trailrat Posted July 13, 2015 Posted July 13, 2015 Thanks for all the replies and to the OP! I had a test ride on my new DH rig this weekend, and was pretty sure I needed more spacers or a bar with more rise. My previous bike was a Medium, and this one is a large. I was running zero spacers, and the front end felt heavy and glued to the ground. You answered all my questions nicely. More spacers, and think I'll cut my bars down to 780mm. ( Currently at 800mm.) Will give some feedback next Monday.
Trailrat Posted July 14, 2015 Posted July 14, 2015 Whats wrong with 800? They should be idealI thought so too! But I looked at some photos of myself compared too other better riders, and I look seriously uncomfortable on the bike. Remember The 800mm bars were fine on a medium with a shorter top tube. Going to a large the with a longer top tube, the 800's just doesn't feel great. Also keep in mind that 780 is pretty much the DH standard. If I remember correctly you are quite a big guy....800mm should fit you better than me.

popcorn_skollie Posted July 14, 2015 Posted July 14, 2015 or a shorter stemits a dh bike so probably direct mount

Going up a frame size stretches you out over the bike more. I am also tall and recently went to an XL Enduro frame. The front end also feels more planted than the old frame. This can be overcome by adjusting your technique and playing with bar height and stem length. For me this slight trade off is far outweighed by the extra room on the bike and improved climbing ability...
raptor-22 Posted July 15, 2015 Posted July 15, 2015 You don't want a long steerer since long columns flex and that places stress on the headset bearings and generally makes things feel less stiff and precise
Skylark Posted July 15, 2015 Author Posted July 15, 2015 So the ideal if you don't mind cutting the steerer down is lower steerer height with higher bar rise to achieve the weighting you looking for?
Eddy Gordo Posted July 15, 2015 Posted July 15, 2015 Just put the spacers above the stem, therefore lowering the bar
