Upgrade a Sora triple to 105 double

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Upgrade a Sora triple to 105 double

How much would a bikeshop charge to upgrade a sora 8 speed triple to a 105 10spd double? I would buy all the components and take them in myself. Wondering if this is worth doing.

The bike is a 2007 Trek 1000 and was a gift. I wish I'd had the option of getting a 1500 at the time with the better components.

It depends on what the shop charges for labor. Visit parktool.com and do it yourself. You would need some tools, but you will save yourself some money.

FYI, I have a new take-off 105 group I am looking to sell. PM me if interested.

it depends a lot on the shop. some don't like you bringing in components and will make it expensive. where do you live, btw? Maybe someone near you could show you how. it's not hard and shouldn't take more than an hour or two

I live in CT, near westchester. I'd love to learn how to do the upgrade myself.

Btw, that quote from mr_tom is awesome.

+1 to doing it yourself. The tools should be around the same price as the labor, and you'll have the tools for the future, which will save you money on overhauling the bottom bracket, or tightening the crank.

an upgrade to 105 would be better for sure, but if you're going to spend the money you may want to do ultegra...

Although if Rankin will give you a good price that would be a pretty slick deal
