Cost to install a groupset

[wildeny]

Short question: how much is the installation charge of a groupset in a LBS in US? (as compared with the price in a online store)

Is LBS willing to install a groupset for you, at some fee of course, even though you bought the groupset elsewhere?



This is my new Ti bike bought in May. Just completed a 400k brevet on this bike in June. Will attend the 600k even in July (in 11 days!)

I use the groupset from my old bike (Fuji FinestRC 2009) on this bike frame (with a Columbus carbon fork, a hand-built wheelset ~ 1380g).

Last weekend, during a group ride my left shifter lever (Shimano ST-R700) didn't work well. Later checked in a LBS and found out something was broken inside. Then realized brake/shifter levers are quite expansive

Now I have two choices: (1) replace a new pair (Shimano 105) or (2) upgrade to a new groupset (e.g. Sram Rival -- lighter than Shimano 105). Certainly (2) is more expansive but it will give my Ti bike a whole new feeling (not a mix of new & old stuffs )

Since I'm leaving for US in the fall for one year, I am thinking whether it's cheaper to do the upgrade there or here. (right now a friend lent me his used 105 left lever)

PS: Wish me good luck on the coming 600k brevet. I wish to get the Super Randonneur medal.
