Ultegra vs 105...(9 posts)

Ultegra vs 105...asphalt assault
Feb 11, 2003 1:37 PM
I'm in the process of selecting some components (hubs, STI shift/brake levers, rear der) for a bike that I'm building. I was going to go with Ultegra but I like the option that 105 stuff comes in black and I'm into the stealth look. I'm just wondering if there will be a very noticable differance in performance between the two.

I'm primarily an MTBer and will be using this bike for road training, I won't be doing any racing but will probably be doing a century or two. Reliability/durability is my biggest concern while having a bike that weighs a few grams more then the next guy doesn't bother me a bit...after all, I ride a 30-something pound FS rig for laughter and entertainment:^)

Will I be missing much if I step down to 105 from Ultegra?

Thanks for your thoughts!

this question comes up often in the components board, but according to shimano website, full grouppo spec'd out with hubs... less than 1/4 of a pound difference.

Very little differenceKen of Fresno

I used to train with a guy on our team (waaaay back then) that was an olimpic alternate. He trained and raced (and often won or at least placed) on a full 105 Giant. I would be coughing up a lung on my Dura Ace Cannondale while he was breathing through his nose. Kind of humbling. It is absolutely "not about the bike."

That said, the one are where there may be a little discernable difference is in durability. Maybe. I really think though that if you properly maintian the bike they would be pretty close to equal in that respect as well.

Best of luck,

I may be wrong, but it seems to me that while silver will always be classic, the "black" movement sweeping components will have the same shelf-life as purple anodyzing. Just my 2 cents.
Yeah, maybe I oughta' expand my horizons a bit...asphalt assault

My MTB looks like it was dunked in a vat of black paint, my truck is black. My entire wardrobe is predominantly black, my hair is black (with silver trim LOL).

I just might dare to be different and go with the silver Ultegra. It's only a coupla bucks more so price isn't really the big issue here...purely cosmetic.

Ultegra vs 105

RD:
- pulleys ceramic bushing/sealed bearing vs sintered alloy bushing
- pivot seals
- sealed link pins

FD:
- lower A-pin bushing
- stainless steel cage vs chromed

cranks:
- better alloy rings

cass:
- carrier vs loose

on 105 the biggest concern durability wise would be the pulleys do not expect bushings to last more then a few thousand miles. If occasionally ride in wet weather or on winter salt treated roads then seals will make difference.

and last I'd suggest against black. It will eventually rub off the cranks and then you stuck with it. If you like black go with black frame/stem/bar/bar tape/post you won't spoil it with a few silver parts.

Not sure about the newest 105 stuff but the older stuff used non-polished bearing races. This results in less smoothness and faster wear. I'm not sure if wear is a significant issue but thought I would mention it.

Like you I bought my first road bike (Cdale with 105) to improve my endurance for better mbt riding. After a few months I was hooked on road riding. Within a year I up graded my road bike to a Kestrel with Ultegra. To me the shifting was much smoother and was well worth it for the Ultegra. Some day I hope to get Dura-Ace. For now the Ultegra works fine.

Good luck!
