Skylark Posted July 13, 2015 Posted July 13, 2015 I'm riding bars 740mm wide with a 38mm rise and 45mm stem and the bars I want to get are 762 20mm rise paired with a 40mm stem. Apart from how it adjusts your reach how does handle bar rise affect handling?What should I keep in mind when selecting the rise? Rise doesn't seem to be riding category specific, the Dirt jump guys generally seem to use more rise but even there some guys use very low rise bars, Slopestyle/DH/Enduro same thing some guys ride pretty high rise right down to almost no rise.
Eddy Gordo Posted July 13, 2015 Posted July 13, 2015 The more the rise the easier it is to handle drop offs etc as your body position will be more back. If the bars are flattish then its better for climbing
Captain Fastbastard Mayhem Posted July 13, 2015 Posted July 13, 2015 Rise also affects how you're able to weight the front end, and comes into play depending on how steep your trails are. Steeper trails call for higher rise, as you don't want to be positioned super low and therefore have too much weight on the front end - have alook at how many spacers guys like Minnaar etc run when they get to the really steep tracks. Lower bars allow you to weight the front end more easily (your weight is already further down there so you don't need to accentuate the movement as much to weight the front end) but conversely they also mean that wheely-ing and hopping are that little bit harder as it's not as easy to un-weight the front end. If you want to get over the front of the bike, then a lower rise is for you. It also helps climbing.
Captain Fastbastard Mayhem Posted July 13, 2015 Posted July 13, 2015 having a look at yours, you will be 18mm lower but 5mm closer. Good compromise.
G00SE Posted July 13, 2015 Posted July 13, 2015 What Ren Man said. Keep in mind you can also adjust final height by adding or removing steerer spacers under the stem.

Skylark Posted July 13, 2015 Author Posted July 13, 2015 So theoretically if you don't need to unweight your front wheel any more then a low rise bar is the way to go? I noticed when going from a 70mm stem to 45mm the handling was so much better, also the weight shift to the back was awesome, much easier to lift the front wheel, wouldn't mind the front wheel being a slight bit easier to lift but I'm thinking even with the lower rise on the new bars the shorter stem will help that in of itself? Apart from adjusting the weight distribution what benefits do riser bars offer, some guys say riser bars make the steering more precise?
popcorn_skollie Posted July 13, 2015 Posted July 13, 2015 Look the reason why jumpers usually have higher rise bars is simply because slopes can get pretty steep and being in a more upright position makes flicking the bar a little easier.But thats it. Your handling is pretty much down to bar width and stem length imo.
popcorn_skollie Posted July 13, 2015 Posted July 13, 2015 I'm gonna try my luck hereYou moving from a renthal fatbar to a spank spoon?

Your handling is pretty much down to bar width and stem length imo. Well watching crankworx this weekend, some guys almost had almost flat bars, others much higher rise, maybe that's each individual tuning the weighting of their particular bikes? Don't think the rise is purely due to the steepness of the slopes or the tricks the guys want to pull or else all those guys at crankworx would be riding bmx sized risers. Check this guys rise: http://photos.nsmb.com/files/4/0/6/3/1/100_2778.jpg Rise must have some kind of affect on the handling? Going from Nukeproof warhead to Spank Spoon
Skylark Posted July 13, 2015 Author Posted July 13, 2015 Also going crazy steep and tricky galore but low rise bars:
Captain Fastbastard Mayhem Posted July 13, 2015 Posted July 13, 2015 Remember there is also another variable... stack height. A BMX has a far lower axle to crown measurement, hence the higher rise of their bars to get it to a good level. But yes. Also all about your fit on the bike. Your height, arm length, torso etc etc
popcorn_skollie Posted July 13, 2015 Posted July 13, 2015 individual tuningThat's pretty much it init. I didn't mean what I said as an absolute statment. But rather why its such an apparent option in the dicipline. Not all bikes are the same and riders come in as many shapes and sizes as bikes do. A jump bike with a steeper ha would probably make the rider more comfortable with a bar which has more of a rise and sweep than a jump bike with a slack head. Could be down to tt length and reach the list goes on.
popcorn_skollie Posted July 13, 2015 Posted July 13, 2015 Now that I think about it. You might be onto something. Not so much with rise but more with sweep. mmh. I don't know. I'll think about this next week when I can think better.
Eddy Gordo Posted July 13, 2015 Posted July 13, 2015 Well the higher the bar sits on a mtb the easier it is for one to wheelie. The flatter bars make it more difficult, but this is due to your weight being more forward and over the front wheel
