Upgrade questions... Tiagra to 105 or Ultegra(4 posts)

Upgrade questions... Tiagra to 105 or Ultegratxcross
Apr 21, 2003 7:54 AM
I just noticed that my large chainring on my Tiagra cranks is slightly bent. I figure now is a good time to upgrade (cranks, rear D and cassette. Here are my questions.

1) Is Ultegra worth the extra $? I'm usually a function over form guy, but I particularly like how the black 105 components will look on my bike (all orange and black). I am a rec. rider with the very occasional cyclocross race, so weight is not a very big issue for me.

2) Will my Tiagra brake/shifters work with 105/Ultegra?
105 won't disappoint, and the shifters should work fine. nmOldEdScott

As a general rule, i can't tell a subjective difference if I move up or down one group, but I can tell when I move up or down two.

The "two levels makes a difference" rule sounds about right to me. I did notice a BIG difference on my MTB between XT and Deore. I think there may be a bigger jump from Tiagra to 105 than between the higher groups. I use 105s and they're fine. No problems with crisp shifting.

One other thing to consider is that bent chainrings are VERY easy to straighten. If you don't really "need" to upgrade, you don't have to. (But I fully understand the "need" if you've got it!) To straighten a bent chainring, just clamp it in a large crescent wrench and pry it in whichever direction it needs to go to be straight. I've done it on my MTB rings and it's easy as pie. We MTBers do the same thing all the time with disc brake rotors.
