FD shift problems
I was reading about Jeremy's problem of the front deraileur "only being able to shift up" when first building his Silvio. It sounds like he resolved that. I may be having a similar problem so I thought I'd ask here.
Background: I'm just a few weeks getting acquainted with a Silvio 1.5 that I purchased from ebay. Shimano Ultegra Crankset 52/42/30. ST6510 brake-shifters.
The Silvio was shipped in a large box, only partially diassembled by the prior owner. I put the seat, handlebars, and wheels on; tweaked the derailleur cables a bit, and was soon on the road. The good: I was wobbling around soon after opening the box, all gears shifting fine. The bad: Haven't not built the bike from scratch (nor any other bike), I'm really ignorant of the components I'm dealing with. Trying to catch up.
This is my first recumbent, and first time using combination brake/shift levers. My bike of the past 12 years had an internal gear hub, mtb style gripshifters, and no fuss brake levers. Except for killing my wrists, neck and butt, it was low maintenance machine.
During my latest ride on the Silvio, I suddenly lost my ability to downshift from the FD large chainring. The little paddle that ought to take me down a chainring went slack. It remains completely slack now with no tension, no clicking sound. The main lever however still engages. The bike is in the stand for now as I fuss with mechanism and cable scour the web.
Some quick googling on 'shimano ultegra shifter problems' is showing me that popular as these are, they can be fussy and break quite often.
I don't know if my mechanism is broken, or if I just have to dismantle the shifter and recable... I'll hit the LBS this week should I not figure it out.
Given how incredibly helpful the CB community is, I thought it couldn't hurt to ask for some insight.
Thanks for any help.
