... that I have been a "nice" person to a complete stranger (Go Me! eh?).
I was working on my new trike (only just started) when I saw a lad on a bike stop and turn his bike upside down, fiddle with it and then right it and try and ride off.
Nope! Off again, rinse-repeat, still
Nope!
I wandered over and asked if he needed any help? "Yes Please Mister".
Chain was off the chainrings and jammed between the rings and the bottom-bracket shell/axle.
We carried the bike to my house so I could work on it. He was worried he would miss his Barber's appointment so I told him to leg it and I would fix it while he was there.
I took the chainwheel/crank off and freed the chain. Put the chainwheel back on and then I spotted a problem (well lots of them actually). First one was that he had legged it without his wallet which was in the crossbar saddle-bag thingy.
So I went to all 3 barbers in town to try to save him embarrassment. But we must have crossed paths somewhere.
I caught up with him back at my place and handed him his wallet. He went off on the bike to go pay the barber.
He came back about 15 minutes later to say the bike was "broken". I checked, yes it was. He called his Mum and I offered to look after his bike till they could come and collect it later.
Off he went for a 20 minute walk home.
I looked at his bike (which his Mum had said had just been "Serviced" at Halfrauds).
Here is what I found/corrected:
The chain had jumped off the smallest chainring and was physically jammed between the chainwheel set and the bottom-bracket shell. Bike unrideable.
Triple chainwheel removed and chain freed. Chainwheel put back on.
Things found to be wrong/incorrect.
- Master link in chain incorrectly installed (upside-down), it is a curved master-link and is meant to follow the chainwheel's and sprocket's orientation.
- Bottom Bracket bearing was very loose, with 1.5 mm end-float.
- Ferrules of multiple brake/gear cable sheaths broken/split/rusty, cables not seated properly in the cable guides.
- Front forks were pointing backwards – 180° out of phase with handlebars.
- Both gear shifters were found to be hard to operate and some gears are un-reachable.
- The smallest sprocket on the rear cassette “rotates” without producing drive to rear wheel (this is broken/unfixable).
- Suspension spring not engaged and rear suspension frame was clanking up and down until the spring began to engage.
Things fixed by Me/recommendations:
- Master link in chain installed correctly.
- Bottom bracket bearing adjusted to run freely without excessive end float.
- All broken cable ferrules cut off and replaced with nylon ferrules.
- Front forks turned through 180° to face forwards.
- Gear selection optimised (shifters are not really any good).
- New cassette free-wheel needed, available for c. £15 on e-bay.
- Suspension adjusted to be always engaged without “free-play” in the link.
Bike is now rideable at least, but I would recommend it is looked at by a professional bike mechanic to address all the issues found. The parts are relatively inexpensive, but labour costs are high.
So, I didn't do any work on my stuff at all, butI hope I have helped a young lad & his folks.
