Anyone know of bar ends that fit 25.4mm or 31.8mm handlebars? If so who is the manufacturer? Thanks.

Are you talking about bar end shifters of mountain bike style bar end handles? In either case, stem clamp diameter won't make a difference. For bar end shifters, the internal diameter of the tubing is what's important. For the clamp-on hand grips, it will be the outer diameter at the ends of the handlebar.

With the exception of Santa Cruz Juliana bars, handle bar diameter where the bar ends are installed are 22.2mm in diameter. The width of the bar at the stem doesn’t matter for bar ends or grips.

Unless he's talking about bar end shifters, in which case it's the inside diameter that's relevant and not all handlebars will accommodate those.

Try to find some rad Onzas!

Hadn’t thought of that but I’ve never run across a barend shifter that didn’t fit a handlebar. Road bike bars have a 23.8mm outer diameter and generally have a thin wall. Mountain bike handlebars vary a lot in terms of wall thickness at the end even though they have a 22.2mm outer diameter.

The Onzas i posted above on my Cannondale are on Kestrel straight Carbon bars ( zero bend, zero rise that I got a a trade show). I needed Kestrel-supplied inserts so not to crush the carbon.

I've encountered a few crabon road bars that don't take barend shifters. One also has to be careful when wanting to install inverse brake levers or barend shifters on porteur/northroads and the like as some of these style bars will not accept them.

cyccommute 

Those are both different issues. It’s not that barends and barend shifters won’t fit, it’s that carbon can’t take the stress.

It's bar ends, not bar end shifters. Bar ends typically fit 22.2mm bars. I need a pair that fit 1" (25.4mm). Can also use a set that fits larger than 1" and I can find shims to make them fit. It's a long story about why I need them, but does anyone know of a brand/model which will fit 25.4mm or greater? Thanks.

nahh, the ID of the ends of some bars is too small to accept barend shifters or inverse brake levers. Like these Nashbar branded carbon bars I have, plastic bar plugs that come with bartape will stay in without stuffing some bar tape in with 'em, so I tried putting barend shifter in and it was a nogo situation. Now I'm curious if a barend shifter will fit in the Easton bars I have. The bartape plugs seemed to fit as usual on the Eastons but I haven't tried putting a shifter in there yet.

LesterOfPuppets

So you want barends that you can fit near the stem of your bike?
If not, all MTB bars I know of 25.4, 31.8, and 35mm are 22.2 in the grip area, so regular barends will work fine.

If so, you can move some regular barends in towards the stem on some flat bars, but probably not possible on some risers...

cyccommute 

Not that I know of. As mentioned before, they are 22.2mm to fit on the grip end of the bar. Of course you could drill out a set of 22.2mm to fit 25.4mm

add another handlebar to the exception list

this Crossroads was equipped (from factory) with odd ball handlebar - handlebar ends smaller diameter than 22.2

found this bike at a flea market years ago and gave it to my FIL

when FIL stopped riding I wanted to replace the grips before finding another home for it and got a unexpected surprise

could not find grips for it - so replaced the handle bar

Machining a set of 22.2mm bar ends is a possibility but there won't be much material left to provide strength. If I can't find a set that fits off the shelf I may do that and test the strength before riding.

ratalish

The bar ends need to go at the end of the handlebar, not near the stem. I only mention the sizes larger than 25.4 since it'll be easy to fit shims to those.

LesterOfPuppets

Why not tell the long story, trying to guess at what the situation is is difficult. Are you using 25.4 straight tubing as a handlebar? No brakes or shifters I guess? Is it for a stoker bar? Why not get an actual handlebar?

Hmm, so barends to fit a tube of some sort with 25.4 outer diameter? Maybe you could dig through the bins at a Co-op and find a pair that are overbuilt enough you could bore them out to 25.4. Seems like some of the longer ones with the dogleg would be more likely to have more material in the clamp area, then I'd cut them down some.

Do you intend to be putting a lot of stress on them, like All out thrashing sprints with all your weight on them?

LesterOfPuppets

If shape isn't very important, and price is no object, you could get this, cut it in half and shim it down. I'd hate that for normal MTB usage but if this isn't for normal MTB usage it could work...

Best you tell that story. There is more than one way to skin a cat.

chain_whipped

They do exist but less common. Search the brand Scott (mostly known for handlebar/ aero bars and ski poles). I have the straight 25.4 with slight bend at the end, another set that's a road drop bar end and used on a modern carbon 29er hardtail mtb. If you're unable to find them, just get the aerobar clamp-ons and cut them down.

OK. It's for a recumbent. [I ride a Vendetta...if you want to see it go to the cruzbike.com website and select the V20c]. I recently developed lateral epicondylitis (tennis elbow). If I rotate my hand 90 degrees on the handlebars the pain drops significantly. Bar ends allow me to rotate my hand 90 degrees. My handlebars are 1" OD which is why I need the oversized bar ends.

LesterOfPuppets

Hmm, they should be 23.8mm if they have road shifters on 'em like these. Maybe 25.4 including bar tape. I advise against clamping around the tape though, you'll want to clamp directly to the bar.




So what position are we going for? Vertical off the tops? Horizontal off the ramps? Or Hz off the hooks or ends?

Jeff Wills

OK, now I get it.
Have you talked to TerraCycle
https://t-cycle.com
? They make a wide variety of recumbent accessories, clamps, brackets, and thingamabobs. If they don’t have something that works, they can make what you need.

FWIW: unless the clamps on the brake/shift levers are custom, your handlebar is 23.8mm diameter. That’s the standard diameter of a “road” handlebar.

LesterOfPuppets

Since we're on a bent, the barends should barely have to bear any weight at all, so I'd get the beefiest looking aluminum barends I could find and bore them out from 22.2 to 23.8. I did this with coarse sandpaper (then graduating to 400 and 800 to finish) wrapped around a dowel once. It takes a while, but just sit down in front of the TV and take your time, keep working your way around so you don't go too egg-shaped, do frequent fit checks so you don't go too big.

Going on decades-old memories here, but I believe BMX bikes with quill stems (i.e., for threaded forks) usually took handlebars that were 25.4" in the clamp area. Maybe you could buy a couple of those stems and use them as bar ends, cut to your preferred length. (Not the BMX stems with the big square four-bolt heads; the conventional-looking single-bolt type.) (Not that the four-bolt type wouldn't work.)
