You need the Shimano Dura Ace bar end shifters. I found it cheaper just to buy a pair of the SJS thumbshifters. I bought them back in 2004 and they still perform faultlessly.

Tonolina, I have a question re your setup with this type of shifter: do you run yours inboard or out of your brake levers?

ta in anticipation.

Like these?

Thanks.

They are on a set of riser bars and sit inside the brake levers. If you are after a nine speed set, there is a single nine speed right hand shifter on the SJS site -

You can pair it with any cheap left hand / front shifter and do the job for about £50.
