Hi, I have a great 15 year old hardly used Mercian race bike with shimano 105 sti 8 speed gears. A while ago i stupidly removed the central Allen bolt from the right brake lever and all went wrong, now lost the bolt and I been told by local bike shop that hundreds of parts will be misaligned now and only option is new lever. 2 questions, does ths make sense and what are my options of a replacement ? I'm struggling to find a single replacement lever of same style so can i for e.g go for a 9 speed lever ? Appreciate views please !

when a sti lever fail for any reason the only option is to replace it . as of today sti levers are only sell in sets . you can not buy just the left or right one . you might find one on ebay . there are no replacement parts for these things .

Ok, thanks. Can I use a 9 sped lever to work 8'speed cassette as these tend to be more available on eBay ?
Cheers for the fast response, much appreciated mate.

No. Each different speed cassette requires it's own lever. You can replace the rear assette with a 9 speed. The only problem you will run into is 10 speeds are now the style. :(

Ok, so if I went 9 speed cassette Which makes sense, could I upgrade using same rear wheel and would I need new chain and front chain rings ?
Why wouldn't I just upgrade the right lever to 10 speed and rear cassette, could I still use the same rear wheel to house a 10 speed ?
So manynquestions, appreciate you support here ? What would you do ?

You can put on a 9 speed cassette and chain if you can only find a 9 speed shifter. I would avoid 10 speed as the cassettes and chains are much more expensive. Your wheel and crankset will be fine, 8 or 9. Since it is an older bike, I would consider 8 or 9 speed bar end shifters and separate brake levers. Apparently you can also use Campy 10 speed shifters with your 8 speed and they are reasonably priced from UK sellers. A current thread in C&V.

Either upgrade to 10 speed or stay with 8. Shimano still has a legacy gruppo in 8 speed..http://www.ebay.com/itm/Shimano-2300-8-speed-Double-STI-Levers-/140701060490?pt=Cycling_Parts_Accessories&hash=item20c26fcd8a (http://www.ebay.com/itm/Shimano-2300-8-speed-Double-STI-Levers-/140701060490?pt=Cycling_Parts_Accessories&hash=item20c26fcd8a)There is also another company called Microshift that makes Shimano compatible derailleurs and shifters in 8,9, and 10 speed http://www.microshift.biz/pviewitem2.asp?sn=676&area=45&cat=168
