What is the actual difference in the stack height of the avenir stem vs other stems?

It is slightly higher than the one it replaced, by a very few millimeters, but it was the highest that I could find. I needed any additional height because my shoulders were hurting.

I had to remove a 5mm spacer to get it to fit properly. That is the same as the 490 degree Bontrager stem which I suspect is made by the same place. Having to drop the stem this additional 5mm somewhat negates the additional rise, but not completely.

In my case, the stock Cannondale stem was removed along with 10 mm worth of spacers to accomodate the new Avenir stem, which measures 45mm - a perfect fit. They have a cautionary note that states that you need to be sure you've got 45mm to work with, either current stem sleeve height or with spacers combined. Thus, your fork steerer tube needs to extend at least 45mm. As far as bar height, you're dealing with differences in angle and stem length. I'm quite happy with the rise on my handlebar.

The handlebar stem I was replacing had the diameter etched into the surface. I think it was etched below the minimum insertion line. If you don't see that, you can measure the diameter or measure the circumference and calculate the diameter.

How much difference this will make depends entirely on what your current stem is. If you look at your bike's specs that should tell you. For me, this made a huge difference! It brought my handlebars much closer, which resulted in less bending of my back, and it lifted my handlebars upward, which resulted even more in less bending of my back. It is lightweight and strong and affordable, and I think it's the best option out there to achieve a more upright riding position.

I replaced a 6 degree 120 mm stem with it. The old stem was long low and aggressive. The Origin8 stem is much kinder to the neck and upper back. I plan to get another one for my other mountain bike.

Top opening is 3 1/8". Stem opening is 1 1/8". I am happy with the sturdiness of the unit. Make sure you have the correct orientation when you install so that you can slide the base of your stemware onto the racks.

I really don't know. What i know is that i have measured the stem on my mountain bike before buying this stem. The original one was larger in diameter so i had to use a shim which i also bought on Amazon.

I wanna say (from memory) the diameter was just a shade over 1/2"? As for the length, 2" about? I remember when i tapped the holes for the stem all I had was a 1/2" drill bevel and it was just slightly smaller than what the stems were. I ended up just cheating the hole by drilling at a angle to open up the diameter of the hole. Then i just pounded it down with a soft mallet. It was a snug but solid hold.

Absolutely Matt, the Stem length is about 4 and half inches exposed for all stems.

Tom, mine are on 1 1/2" short rubber stems and they're fine. I'd imagine with 2" or longer stems they may get woobly.

The stem diameter is larger that most standard bike stems. Be very careful to measure the existing stem diameter. I thougt it would all be standard. Not true..

you can order a stem riser from amazon. I ordered and installed one - it raised the handle bar height by about 5-6 inches. If you don't like it you can always return it (for free if you're a "prime" customer and the item is prime eligible, which i'm pretty sure it was). I ordered the Delta stem raiser for about $28.

I purchased one and it is 9" tall in total. Approximately 4 " is the stem and the rest is 5" :o)

Realistically about 3" with the riser only. But if you buy an adjustable stem you can gain a couple more depending on the stem and how you use it. I gained a total of 5" using both. Could have gotten 7 with longer neck stem and adjusting it almost to verticle. Will change the feel and handling of your bike so be ready to experiment with the best setup for you. Also your cables will need to be changed to longer ones if you go too high, I had trouble finding cables that would be long enough and had to lower the bars a bit to make them work.

My stems are larger than 1" and there is still room. So I would guess 1 1/4 to 1 1/2 inch stems

k stems are thinner, and are more rare. 3/8 inch which is 6/16 vs. b stem which is 7/16 diameter. most likely your chair is a b stem, but I have a chair that uses a k stem

The "41" is the height of the clamp. The "85" or "105" are the length of the stem from clamp to handle bars. The listing is confusing because it says it's 110 length and then asks you to chose 85 or 105. Raises up to 60 degrees. (Zero being flat out and 90 degrees being straight up)
