Hi Derek
What year is the bike in question?
Offset bushes have been discussed at length on here.
They are available from lots of suppliers
This seems the cheapest place
Goldtec and TFT also sell them.
They lower the BB height by up to 1/2 an inch and slacken the HA by a degree or so. You can get them to fit any bike if you know the measurements for your shock hardware.
Use this guide to work out what you need
As the alpine link appears to be rarer than unicorn hair nowadays, this might be the best option.
There can be clearance issues- if you search for some of the threads on offset bushes on here you will find it all explained!
These bikes do have a high BB compared to modern frames so lowering it is a good idea.
My bike is a 2006 model and this review[quote]Changes over last year are immediately noticeable, with less tip toeing needed to get into the lower saddle. Dropping the bottom bracket forward and down also removes the precarious ‘teetering’ feel of last year’s bikes.[/quote]and the third from last comment on this thread
you can see why they are fitted standard on the 06 bikes now.
Make me think that the standard link was changed to the alpine link for that year, but having measured my BB at 365mm (140mm pikes) it is still on the high side so either the 06 bikes are the same as 04-05 or the earlier bikes had even higher BBs. the teetering feeling is still there!
Good luck sorting your friend’s bike out- I saw on your wtd ad that someone reckoned jejames in chesterfield had an alpine link- did you find out? Or I see john above has offered one
