First homebuilt swb bent

Mountain bike stems extend the bar more, but typically are designed for
1-1/8 threadless systems.

The handlebar on my home built is just a long piece of 1" aluminum welded to
a short cross-piece. I also made a pivot at the junction. This was as much
to make it impossible to bend the thin tube as it was for the pivot effect,
but the effect was nice. At slow speeds, I put the bar back towards my lap
for more tiller, but at higher speeds, having it more vertical gave more
sensitive steering.

If you need to push down on the drive side (top) of the chain, you
absolutely will need an idler. For slack or low friction areas, 3/4" black
irrigation tubing works fine.

chain guides, I have seen plenty of arrangements for guiding the chain
most

pvc tubing instead of the jockey wheel arangements. Has anyone every tried
this? What were the results?
Thanks for the advise!

Hi Ken!

Now I'm building my own stems in two pieces. The main piece is attached to
the fork neck (I use threadless 1 1/8" headset) and has a tube welded to the
head piece. On this tube, I use an aluminum 1" tube to provide some length
variation capacities. The second piece, provides the attachment of the
handlebars to the aluminum tube.

To my chain idlers, I don't use skate wheels, because they are too weak. My
creations are mainly front wheel drive and I need strong pulleys no manage a
twist chain system. I use to make my own idlers with two ball bearings each
one and the material employed is Tecnyl (nylon).

If you want, I'll send some pics to you showing the solutions...

All the best

Eduardo
