Lost drive

[Valiant]

So my after many years of faithful service my Gipiemme Tecno T30s seem to have given the ghost. They no longer seem to drive, ie the cassette has no purchase. Only once every 7 revolutions or so does it catch and drive forward. Is it terminal?

Might be recoverable; maybe the pawl springs have failed, or it might just be gummed up

The problem may be getting spares if something has broken.

O.oh there's hope Thanks MV. I shall disect the fooker.

Dribble oil into it, spin it. Probably gummed up.

+1 on that, Gummed up is the most likely, try and get some thin oil into it.

I assume 3in1 is too thick?

[mrcharly-YHT]

old 3-in-1 used to have a resin in it and was notorious for gumming up hub gears.

A bit of engine oil would be fine for your freewheel.

TFT2 oil by wedtite.

Thicker than GT85, not quite as thick as 3 in 1.

Is there any way to get directly to them?

If this was Shimano then the freehub could be flushed and relubed - or replaced. It needs a 10mm hex key once you remove the cassette and spindle.

Replacing a Shimano freehub is actually cheaper than flushing and relube.

I can't find any on line pdf for maintenance so I suspect the only peeps who can tell you how they go together is the LBS.

It's a Gipemme

You can't hurt it by taking the cassette off to have a look.

Google suggests the freehubs are removable - it suggest that certain models could be changed from Shimano to Campag - and the odd image I can find (search: Gipiemme Freehub) shows the freehub separated so it may be like the Shimano fitment which IIRC is a 10mm hex.

If you can get the freehub off then a soak in GT85 wouldn't hurt.

Also if you can remove the freehub then it can be replaced . . .
