Shifters

I can't find the answer in the search feature....

I have a Trek 1000 and I do not like the shifter/brake lever combo. I would like to upgrade to a tiagra or 105 type lever and shifter. What do I have to do, and what do I have to buy to make this upgrade.

Just for info, it is an 8 speed rear and triple front.

If you want to buy new (as in 10 speed), you'll need the new STI shifters (triple left/front) and a new 10s cassette. Your rear hub will take the 10s casssette and the required 1mm spacer with no problems, and your front and rear derailleurs will work just fine, too.

If going to a 10 speed, won't he need a new chain also?

Shimano does make a Tiarga level 8-speed with some other designation. Their website is a bit off the mark today.

8spd. is rare and getting rarer. Tiagra-level is your best option, and can be done in the $150 range, I would imagine. You'd only need to swap out the shifters.

The advantage of the 8 speed stuff getting rare is that it is getting cheaper in the process. Just a thought.

Snag some 105 8-speed brifters off eBay, maybe 75 bucks. Everything else will be fine.

And a new 10-speed chain, and, oh yes, new bar tape.

You must be talking Shimano not Campy. Campy 8 sp is getting real expensive.
