those are very well made, good job. Delrin is a good material to use for them .... light, real stiff and easy to machine
I bet you will sell a ton of them.
found a set of bars this summer that had extensions like these hidden under the grips. they were made of wood, probably made a long time ago.
I taught it was a great idea, it makes the bike more confortable to ride.

Really interesting and I think a viable idea, but I have some reservations. What have you suggested for installation? I am wondering about affixing them into the bars. Is there any other procedure than whacking them into the ends?

I could conceive of a critical failure if one came loose for any reason while riding especially a motorbike! At minimum I think you would need additional all temperature epoxy or pin them through the bars or create a quill type arrangement that's tightened from the end but thats more complicated.

In the end something to consider is the coefficient of expansion btw the two materials. Delrin is probably pretty stable within a wider temp range than steel tubing the bars are made of....If you live in a temperature stable climate you might never be at risk but a wider cold to hot climate could potentially work them loose.

Safety First!

After thinking "good idea", this was my second thought.

Nathan, I twisted a set out of aluminum, and I whacked 'em in. They're REALLY tight! I like your pin idea.

#1. are these solid or have a void in the middle?
#2. are both sides capped or just the outside?
#3. how far do these extension go into the handelbar
#4. are they difficult to remove without damaging the bar?

These are solid. 2 inches into the bars. 4 inches stick out. And they are a snug fit. No damage to the bars.
