Steven Knoetze (sk27) Posted March 9, 2015 Posted March 9, 2015 Hi guys,So I bought an indoor trainer cheaply and then realized I needed a wheel, cassette and slick tyre to run my Giant Anthem on it. I picked this up off of Gumtree for the same price as a wheel.I am hoping to identify what it is and what it is worth(whether I paid too much). I am from a MTB background with no road cycling experience at all. This was the adverts description: Ciclo Aluminium road bike, size large. Great bike. Brand new Serfas Seca S tyres, Shimano Exage 300Ex rear derailleur, Shimano Sora front derailleur, Shimano Exage hubs, Airline 2 Vuelta rims, Sti brake/gear levers with Shimano Exage brake calipers, Velo Kevlar Crossbow seat, 2 x aluminium bottle cages, new handle bar tape, Cateye wireless bike computer. I am also battling with the right shifter. It does not click for the gear selection or return back to it's position which gets interesting when you need the right brake lever!! Pushing it does move the rear derailleur though so it is the selector that is faulty. Any info on how to strip and repair the shifter would be appreciated as well as any info on the bike itself.
Spinnekop Posted March 9, 2015 Posted March 9, 2015 Any info on how to strip and repair the shifter would be appreciated as well as any info on the bike itself. It is a VERY old bike. All that I know. As for the lever. Tried it once. Dismantle. No problem. Put back together.....cannot be done.I have heard of a legend that there was a mechanic in Pretoria once that put a STI together without breaking it but I never got to shake his hand.Coolheat (Agents) said it cannot be serviced so I tried myself. I threw it away and bought Campagnolo ever since......now THAT you can service! Good luck!
MintSauce Posted March 9, 2015 Posted March 9, 2015 Rumours suggest there is a bike mechie in Cape Town who can disassemble an STI and then, retracing his steps, can reassemble it, on a good day. There's also a rumour that there's another mechie in the Mother City who can reassemble an STI if you hand him a box of parts. I think his name is 'Fiekie' or something like that...? I cannot confirm or deny these rumours. That is simply what I have heard.
Steven Knoetze (sk27) Posted March 9, 2015 Author Posted March 9, 2015 LOL, these "rumours" sound like they originated from a certain Mr Jeremy Clarkson.Some people say there is a bike mechanic...........Thanks though guys, any reply is appreciated.
Jules Posted March 9, 2015 Posted March 9, 2015 It is common for those old Shimano Sti levers to seize up. Disassembling them is not necessary. Simply take the lever off the handlebar, remove the rubber grip, and dunk the whole Sti lever in a jar of diesel. Leave overnight. Take the lever out, and let the excess diesel drip out onto newspaper. The lever should work.

There appears to be a spring inside which is not returning the lever back to it's original position.It is hard to explain when typed out.

Simply get a can of Q20 and spray it inside the shifters while trying to shift them up and down. Its usually just a build up of old grease inside the shifters that need to be loosened up.. Spray the whole can out in the them, That should do the trick.. When they start working throw in a bit of machine oil to re-lubricate it.. ...

DJR Posted March 9, 2015 Posted March 9, 2015 Also make sure it is not a bad or gummed up cable. "Return" that doesn't happen is often because of a cable issue. (B.t.w. I like the diesel and Q20 ideas.)
David Marshall Posted March 9, 2015 Posted March 9, 2015 I've "done" one of those! (5 hour job and you can't get any parts). As suggested above clean, flush and lube. If that dose not work see what your time is worth before progressing. The one I did I was able to beat and file the lever so that it engaged when positioned by the spring (it had worn down). Not worth the labour though. The frame could be a Shimano from way back.
Steven Knoetze (sk27) Posted March 11, 2015 Author Posted March 11, 2015 What did you pay for it if I may ask?A grand total of R1200.
