The drive-side idler on my SMGT has died, more specifically the smooth elastomer-ish bit that the chain runs against has disintegrated from wear - the bearings themselves are fine.

Does anyone have any ideas where I might source a replacement that doesn't involve selling my soul to HPVelotechnik?

(Note that this is the older GT model - they changed the idler in the GTE, and the Terracycle offering doesn't fit.)

It looks an awfully lot like a section of large-diameter hose.  I could probably get a metre of that and a hacksaw...

May be worth giving Mike Burrows a shout... May have something lying around or be able to make something suitable.

I found a source of fuel hose (which I assume shouldn't get too upset about chain oil) of almost exactly the right dimensions, so I'm going to give that a try in the first instance.  Even if doesn't stand up to the wear very well, you'd get a lot of replacements from a metre of hose.

The size is good, but the steel reinforcement makes it a bit lumpy at the edges.  Not sure how much of a problem that's going to be in practice.  Will find out when I ride it...
