A couple of bikes that I have been interested in are equipped with the Shimano Tiagra, Sora, and 105 groups. If I never looked down to see what set I was riding with, would I know the difference? Is the difference less apparent, as in longevity of components or durability. The Trek 2200 with 105 components is up to $600US more that the 1200 with Tiagra components. Is there really that much difference? I have noted that in many publications and on this forum, I seldom see anything less than 105 discussed.....guess there must be some reason. I just don't want to make any major mistakes on my firs road purchase.
Thanks
John

HuffyMan,
I am also new at this stuff so have only limited qualification to comment, but here is my 2 cents worth. From what I have read and heard, I would not buy anything less than 105 in Shimano. You can look at some of the parts and see a definite difference in the finish and at least the apprearance of durability. I may be a little prejudice though, because I just spent a bunch of money upgrading to 105. After that, let me assure you that the extra $600 for a complete 105 group is a bargain. I have heard it this way, that there is a big step up in quality from Tiagra to 105, but from there to Ultegra then Dura Ace becomes more a matter of weight savings.

On the other hand it seems that even the lower end Campy groups are pretty good.

Other comments?
Regards,
Raymond

In times gone by, there were two worth mention.
First there was shimano 600 then dura ace, then came 105 which took the place of 600 though not quite.
Then came ultegra which took the place of dura ace though not quite, where this left dura ace i don't quite know.
Anyway to go with less than 105 would be most pitiful.
Add heresy add nauseam.!!

Thanks for the replies, I guess the old "get what you pay for" addage applies here as well. Then the 105 it shall be.

In the lower shimano stuff certain parts are molded from plastic and as you go up in the range those plastic parts are machined from aluminum and are a lot more durable and stronger...
