    Comments about Nashbar OS Stem:

    This stem is working well, and was a good value.
    The directions indicated tightening the top 2 (of 4) bolts until the face plate made contact with the stem, then torqueing the bottom 2 bolts to spec. I followed this, and all is good. The more common practice is to evenly tighten all 4 bolts. Probably would be fine either way.

          • Silver screw color doesn't match black stem

          Comments about Nashbar OS Stem:

          This stem perfectly fits the bill. I usually ride a "large" frame, but found a great deal on a past-season "medium" Marin. Swapping the 90mm stock stem out with Nashbar's 120mm did the trick to improve comfort and riding position.

          The stem itself looks to be of high quality, and I have over 100 miles on it at this point with no problem. Probably not the lightest stem around, but it wasn't noticeably heavier than the one I swapped it out with.

          The only downside is that it comes with shiny silver screws, which doesn't match well with the matte black finish on the stem. My previous stem had black screws, so I just used those instead.

              This is a replacement stem after a bike refit. Installs easily. Performance is satisfactory. Not the lightest but very good for the average and high end cyclist.

                  This stem is very well made, equal in quality to stems two and three times the price. It came with stainless steel machine screws which is a very nice touch not found on a lot of higher priced stems. Give it a try. You won't be disappointed.

                    I'm not a racer, good product and price. Graphics a little flashy, but that's personal, does't affect performance.

                        I don't have scale but this is significanty lighter than what I had on my bike. Went from a 100 +20 to this 100 -7. Puts me in a more agressive position and is perfect for my riding style. The prior stem was squeaking and this one is silent. I was considering a name brand but couldnt bring myself to pay 3 or 4 times more for basically the same product minus the name.
