105 vs Ultegra

How much difference is there between the 105 and Ultegra groupsets? Is a newbie like me even going to notice (or care!!)? The new Giant range is just out here and the TCR Alliance is about $400 cheaper than last years model (but with the same specs, best I can tell). So with the discount my friend can get me I'd be tempted to get the Ultegra model. But if I'm not going to notice the difference, I'd probably be better of using the discount on the 105 model and saving my money!

The other question is what's the deal with compact cranks? The 105 model has a 34/50T compact crankset with 12-25 cassette and the Ultegra model has a 39/53 with 11-23. I have no idea what any of that means!!

Thanks!!

ETA: I'll be using the bike for tris, possibly a run/bike/paddle event with an 80k bike leg and probably some commuting (about 30k each way).

Re: 105 vs Ultegra
The 105 is a really nice quality group, the ultegra is somewhat longer wearing but you will be well served w/ 105. For your uses, I think the compact is aperfect option, it gives you lower hill climbing gears without having to go for a triple crank in the front, sounds like a good setup.

Most people who commute seriously will buy a beater bike for that purpose and keep their nice bike nice, commuting in all weather and leaving a bike parked outside is rough on equipment, I've owned a lot of racing bikes and never, everhad a bike lock on any of them.

Re: 105 vs Ultegra
Ella-I'm thinking of bike commuting a little this fall...I think it's a great idea! I too would be parking my bike inside...music room has a HUGE closet

I say enjoy the weather. Everyone at work will think you're a ROCKSTAR!

Re: 105 vs Ultegra
Back when I was naive (oh...about 6 months ago ) I thought it would be fun to ride my fancy tri bike to work once in a while instead of my old steel beater. After I put a few hundred miles on my tri bike I realized that I will likely never commute on it. Here's why (keep in mind this is city commuting):

o In traffic, your hands need to be on the brakes all the time. Not feasible on a tri bike.

o Potholes abound on busy city streets. Tri bikes do not like potholes.

o I often alternate driving and riding, leaving my bike at work overnight. Not going to do that with a fancy bike.

o Commuting requires lots of reflectors, lights, bells, and other handlebar attachments. I am NOT putting a bell on my tri bike.

o Who the heck wants to ride through inner-city neighborhoods on a bike that looks like it's worth a lot of money?

If your commute route is friendly and gentle (bike path style) and you only plan to do it in nice weather once in a while, I think you're fine. Otherwise I'd pick up an old used beater. Commuting is tough on bikes, why trash your fancy race bike?

Re: 105 vs Ultegra
I'm getting ready to start commuting on Monday on my 400 pound hybrid (at least it seems like 400 pounds).... I just added a rack to the back and a pannier....

NOT riding my road bike anywhere near the University.... I've seen bikes bent almost in half over there...(I can't even imagined what happened...)

The other problem would be that you'd have to bring different shoes and all... on my hybrid I can just wear regular shoes and not have to change when I get to class.... it's really freaky riding on platform pedals after riding with clips all the time. My knees keep flying up to my chin and I can't keep my feet on the darn pedals... (I guess that means I'm pulling up plenty when I ride normally, but it's pretty funny looking..)

Can I could this as a strength workout since it's so freakin' heavy?

You're a triathelete. You wear sleveless jerserys. You have no style sence. I would be rocking that bell everytime I passed someone. (sorry couldn't resist the dig 'bout tri people. No hard feelings)

Ultegra is near dura ace. The new 105 is more like the ultegra but since you said this was last years model I think that it is 9 sp. Right??? I would go for the Ultegra model.

You don't really need a compact crank unless you are doing some ride with really big hills or a hillclimb or something like that. 39-23 is a pretty big rollout but since you are going to be riding on a bike path which are generally not really steep it should be fine and I doubt that you will get into your 23 while racing.

Go ultegra

Re: 105 vs Ultegra
Note bike #1 also has decent wheels, while the cheaper one does not. If you go with the cheaper one, maybe they can do a wheel upgrade fror an upcharge, see this thread regaring crummy oem wheels on a giant:

Not to be a hair splitter, but I think the compact crank is the best win-win to come along for women and new riders, the old solution was specing bikes with a triple crank, which was really a less than elegant solution to the need for low range gears, while the compact offers nice low gears with few real downsides for the target audience.

I'm a real fan of the compact, I may even get one myself for cyclocross.

Psst. Hijack. Ella, Sister Madonna Buder (SP?) is still out on the course at IM Canada! You might be the only other tri-peep up to watch. (There's also another 77 year old out there... a guy. I think it's his birthday today.)
