Ebay doesn't seem to be the place for a margin when it comes to Islabike, 700 small. I'm new to Ebay, so maybe it's hard to get bargain anyway. But I bid for one, with my limit at around £300. It was a 5 year old bike, a bit scruffy.
It sold for nearly £400.
A new bike today will cost £499.
3 years ago the bike would have cost around £399!
5 years ago probably cost even less.

Gears suddenly not changing correctly any more.
The rear derailleur started to be sluggish in changing. It would click, click click then eventually go to the cog. I had checked the chain condition a few weeks back and it was ok but I checked it again and sure enough it was stretched a bit too much so I changed it. As I have had three chains on the cassette I changed the cassette too.
But with the new chain and cassette, gear changing was way out. I adjusted it with the screw adjuster on the cable but that was no good.
When this happens, or when the gear changes are good in the outside cogs but not in the middle cogs, check the cable.
Undo the cable on the derailleur and slacken it all the way up to the brake shifter. Click the shifters into the position that would bring it into the small cog on the cassette and push the cable inner wire through the shifter. You may well see that the abrasion on the wire has caused it to fray breaking some of the strands. This will result in the remaining strands to stretch, thus giving the inaccurate and intermittent gear shifting.
This was a bit of a pain really.
I had taken a couple of days off of the bike for one reason or another, and so now I couldn't use it. It would be quite painful getting stuck in the hard gear and getting home. So I improvised a turbo session in only the manly gear.
You've got to be careful using this gearing for a turbo session if you have suspect knees. It puts a lot of stress on them. So I warmed up easily for 5 to 10 mins, and then did a moderate session. If you push at a slow cadence with moderate pressure, the muscles will soon get a good workout even if the heart rate stays lower than usual.
Dancing out of the saddle was good too, for 5 or 10 mins. Again the HR seemed lower than a full out session but the muscles were enjoying it.
The cable should come tomorrow so I'll be on the road. Thank goodness.
