Origin8 Pro Fit Alloy Ergo Stem, 1-1/8" x 25.4 x 17-Degree x 90mm

Origin8 Pro Fit Alloy Ergo Stem, 1-1/8" x 25.4 x 17-Degree x 90mm
I felt a little stretched out on my bike. I wanted to change out the generic 100mm stem that came with it to a 90 mm. The construction and finish on the Origin8 was much nicer than the original. One note, the stack height on this stem is 40mm, my original stem was 45mm. I need to install an additional 5mm spacer on the steering tube in order to get the top cap bolt to tighten up everything properly. Also, I used a little blue LocTite on the face plate bolts to keep them from coming loose.

    Decent height and length boost. Quality looks good. I was initially concerned with the double clamp. After install I really like the clean look of it. It allows you to see the adjustment lines on the bars super easy and looks very unobstructed. Used it to mount a Salsa Cow chipper onto a carbon steer tube works great. Minimal flex.

    4.0 out of 5 stars Before purchasing I used an adjustable stem to determine the best angle to accommodate both my back and my bike

    Performs as expected and met my needs. Before purchasing I used an adjustable stem to determine the best angle to accommodate both my back and my bike, and then purchased the stem that matched the desired specifications. I did compare the angles of the Origin8 Pro Fit with the adjustable stem, and they were identical. I have found that different bikes require different angles and stem lengths, even though the bikes are arguably the same ---- all Trek's and all with nearly identical geometry (it's the "nearly" that makes the difference).

    Fits all bike handle bar types! Very happy with this stems.

    My wife is petite and has a bad back. Her existing handle bars were way too far out on her road bike. This stem shortened the distance and makes rides much more comfortable for her.

    Note: I previously had returned a bike stem (60mm) which promised to fit a road bike. It didn't. This stem however works beautifully.

    Pros:
    - Fits all bike types, including my wife's road bike.
    - One of the shortest stems on the market.
    - Good price, especially on Amazon.
    - Easy to install, well-machine screws.

    Cons:
    - None!

    Nothing much to say. Good price to quality ratio. I use this on my commuter (Rocky Mountain Hammer 1998) with a 620 mm Specialized handlebar. I got the 70 mm x 31.8 mm.

    I'm quite a small guy so I require a short stem on all my bikes. This one fit the bill and so far it's holding up well. It's pretty stiff, IMO. No problems as of yet.

    Highly recommended.

    UPDATE:

    Got the same one for my 96' Diamondback Response Sport, haven't installed but I got it on one day shipping.

    Still looks great and my last one still holds up well.

    5.0 out of 5 stars Good Stem
    Reviewed in the United States on October 10, 2016
    Verified Purchase
    Did exactly what I needed. I have a 54cm road bike, and wanted to reduce the reach (might have longer legs than most my height, and therefore a shorter torso). I went from a 100mm stem to an 80mm (this one), and it helped even the weight distribution and made the ride more comfortable.

    The quality of the stem appears to be good, and it's fairly light. It looks good, and I'm happy with it.

    Mounting it to the bar is a bit trickier than for stem with a "plate", as with this stem you have two vertical brackets. Just ensure that you tighten them all very evenly so that there is an equal amount of screw left showing between the stem and brackets for all four screws.

    Nice looking stem that allowed me to adjust my bike for a more relaxed ride without any funky extensions or adjustable angles. Really like the subdued logo; fits in well with my brushed Ti bike stripped of all logos. Only gripe, a minor one, is that the stem is shiny silver while the clamp bolts are closer to a brushed titanium. Wish it all had the same finish, one way or the other. Still, it looks better than any other option I could find and came in at an extremely reasonable price. I suspect the stem will outlast me.
