Daft question about shifters

[Victor Meldrew]

Can STI shifters (Ultegra circa 97) which have been fitted for double use be modified in some way to
shift on a triple?

Thanks.

There used to be a thing called an Erickson Gizmo that fitted to the cable as it exited the shifter.
You could twist it with a little lever so the shifter went between either the middle and outer or
inner and middle. Haven't seen or heard of one for ages though since triple STIs became available
but someone might have one in a bits box somewhere. I think they were made by Erickson Cycles in
Seattle and you could try e-mailing them at GlennEBike@aol.com Tony

I think the Shimano site had a FAQ about this and I think it said they should work OK. Don't ask me
how though. Check the FAQs on www.shimano.com I looked into this some time ago.

I have an RSX shifter which is triple even though the chainset on the bike is double (cheap french
hypermarket bike came with choice of chainsets) so it is probably just a change of drum or
something. I know RX100 could be converted from 8 to 7.
