Installing Risers
There has to be a better way to install risers.
I searched the forum but cant seem to find how to install them specifically.
My friend said I have to use force. (worked for him, not for me)
He also said theres a tool. Any input would help to guide me in the right direction.
Sorry if this was supposed to be in Bike Mechanics section but I figured more people in here have risers.
I forgot to add theyre 2" answer pro-taper risers with a nitto stem

Some of these bars just aren't meant to go into quill stems, they're MTB stuff after all.
You can buy snap ring pliers that pry stuff open, but they're probably not much better than a screwdriver and another pair of hands. Some shops do keep them around, though, FWIW.

if the bar doesn't fit into stem:
1. check to make sure that the hole in the stem (the clamp) is big enough for the bars. check the diameters of each. technical note: your nitto stem most likely has a 25.4mm clamp. the protapers come in 25.4mm and 31.8mm varieties. naturally, the 31.8mm bar will not fit in the 25.4 stem. from looking at pictures of the 31.8mm protaper bars, it looks like you'd be able to get the stem up to those bends. that's where the diameter of the bar seems to drastically increase.
2. if the bars are indeed meant to interface with the stem, then check to see if the stem clamp looks crimped or otherwise malformed. sometimes idiots will tighten down a stem clamp when there is no bar inside, which will cause the hole to become smaller. you can remedy this as suggested above -- pry it open.
i suspect that once you evaluate the things in steps one and two, you'll figure out what the problem is. sometimes it can be a little tricky to get a stem onto certain types of drop bars, but the agony that you describe is simply not going to happen with risers unless something is afoot.

i'm thinking that it's going to be a two man job of prying, twisting, and sliding. some grease might not be the worst idea.

I have a riser on my fixed gear, probably about a 2 inch rise. To get the on my quill stem I used a large flat piece of hardened steel to pry it open. This was not a screw driver, I tried that and bent it. Just watch the threading on the quill stem and make sure you do not us your lever on the threads. It will work, just use force, not enough to break it though.

If both stem and bar are the same size, but we're talking about an ordinary, traditional type Nitto stem, then those bends are not going to go through unless you somehow spread the stem clamp open as much as it needs. A big, wide, ordinary flat screwdriver tip usually does the trick. Just be careful you don't eat into the aluminum alloy of the stem clamp.

I've had that problem. The simple fix is so turn the bars upside down, to where the "rise" bend is facing the opening on the bottom of stem. Throw a rag over the end of the bars, grab onto the stem and bang it with a hammer. A few swift, strong hits with a hammer get's it through.
Seems drastatic but it does no harm to either components, other than maybe some scratches on the bars from the rubbing, no big deal.
