I'd like to confirm that the quill of this stem is actually 25.4mm diameter, that the clamp for the bar is also 25.4mm, 130 deg x 90mm length?

Quill is not 25.5. However, the gap it's so small that I got away with only a very thin layer of plastic just to cover the gap because it really holds very well. I have a Cannondale " Beast from the East" old school and the stem I was using was killing me. Clam is 25.5. Not sure the angle and length. Sorry, away from home.

all mtb bars ......O.D. standardized @ 22.2mm or 7/8" in the control area (grips, brake, shifters) 25.4MM (1 IN) IS O.D. STEM MOUNT. SOME MTB BARS ARE 31.8MM MOUNT, BUT STILL 22.2 FOR CONTROLS.

This stem is a larger diameter than the "standard". You need to measure your old stem before ordering

You can get stem raisers that go in between the original stem and quill. The brake and or shifter cables may need longer also.

your stem clamp diameter is 25.4 mm according to the lager specs so it should fit fine.

I just measured a lever that I had loose. I tightened the screw all the way down to stop. The smallest the clamp will pull down is about .850-.860" which is about 21.84mm. On the wide side you can stretch it open to about .890" which is about 22.6mm. At those extreme dimensions the hole is no longer round. It was kinda sketchy going that tight, you might induce unwanted stress into the aluminum clamp that could fracture later when in use. It might work ok on an alloy bar within those dimensions but might pinch and crack carbon.

Yes, this is why I purchased this mount. It reduced the bar to the 25.4 size. Works perfect and fits across the stem perfectly. Extends about 2.5 inches and does not get on the way. Compact.

I measured mine and the clamp won't open to 1.5 inches. I looks like it can open to 1.25 inches maximum.

What's the measurement/length of the round part of the handlebars where the stem connects. Thanks

I spoke with a rep at J&B; (manufacturer) and I went on their website www.jbi.bike and determined I indeed received a part that will not work for my bike. I received 58383 but should have received 58391. If you go to their web site you can confirm. The part they sent has a length of 180mm quill (too long per spec given in description) and the fork diameter (stem) is not 22.2mm, it is in fact 25.4mm. I ended up returning the product twice and then bought the correct part from bikeparts.com

This question has a few answers since it has a top cap and quill bolt, luckily, i haven't installed mine... Total length from bottom of quill (titightened) to top of cap:135mm. Total length of adapter with no quill and no top cap:130mm Length of adapter only from bottom to minimum insert line:65mm Length of adapter that can be exposed, minimum insert to bottom of stem: about 25mm Length of stem holder insert:39mm -smaller than most mtn stems... Good product for the purpose.

no, this will only fit on a 31.8mm bar. It does not come with shims to also fit a 25.4mm bar. Some stems come with shims.

Yes Ray, I measured mine this morning and the kit comes with four plastic reducing bushings. Each has an outside diameter of slightly over 2 1/2". It looks like the kit will fit on a 2 1/2" quill without any reducers or possibly a thin metal shim.

I believe it will work my bar is 1.25" and 30.8mm is 1.21" and the clamp still has room to close more.

Well the bars are oversize so the inner diameter of the clamp would be 1 3/8 inches. Hope this helps! If you're thinking of getting this scooter, it's a great scooter. If you have anymore questions, just ask.

It is a 1" quill for older size steel forks. It will allow the use of clamp on alloy stems for handle bars.
