105 Gruppo vs Ultegra....(11 posts)

105 Gruppo vs Ultegra....funknuggets
Jan 21, 2003 8:56 AM
Just got a new frame. Looking to outfit it on a strict budget. I can go used Ultegra piece by piece off classifies and ebay or mix and match 105/Ultegra off icycles... OR a guy I know is offering a 105 gruppo off a bike he purchased with about 2 miles on it including wheels (105/open pros including 2 sets of tires) for $465 shipped.
I would likely end up selling the headset, front DR, and bb. So supposing I could get 50 for those, it is the entire set for $415 including wheels, pedals, and tires.

What is the weight savings/performance difference between 105 and Ultegra? I cannot find a weight comparison for the group. Secondly, do you think that If I only got the parts I NEED, I could get new shifters/crank/rear dr/brakes/cassette/pedals without the wheels for about $400. Price for performance, which way would you go. Sorry about my debate here.... Im thinking getting the 105 but I am waffling. Please help.

I think 105 is pretty darned solid. I have a pair of 105 hubs that are still silky after about 9,000 miles, low maintenance, and I'm no lightweight. When I put a triple on my bike recently, I switched out the Ultegra double RD, which always seemed hesitant for some reason, and put a used 105 triple on it--works like a charm.

I can't speak to the shifters since I use Sachs Ergos.

The polish isn't quite as high as on Ultegra, and 105 parts probably weigh just a tad more, but they work just fine. And now you can get them in your choice of colors!

I think weight difference is somewhere close to 300 g, but I´m not sure.

New is better than used. However, if you get a good price on a gruppo that´s only a little bit used, then who can blame you if you go for it?

If you´re on a budget, you won´t be disappointed with the performance of the 105.

Can´t remember if you were thinking of the wheels as well? If so, forget about them. Shimano´s wheelsets are not a very good buy IMO.

Sorry if I was unclear. I can purchase the 105 group with like 2 miles on it for $465 shipped with everything including pedals and 105/Mavic Open Pro wheelset including two sets of tires. However I dont really need the frdr, bb, and hs, or the wheels for that matter. So Id probably keep the wheels and sell the bb,hs, and frdr and get about 50-65 back.

BUT... I could probably piece together new/slightly used 6500 crank, brakes, sti, cassette, chain, pedals and rear dr for around $400 not including shipping costs. So my question ultimately is getting an extra wheelset and two sets of tires worth going with 105 for about the same price.

no matter what you decide it won't be a mistake. Blindfolded (figuratively), I doubt most people could tell the difference between 105 and Ultegra.

It's always nice to have extra wheelsets and tires. But if psychologically it's going to bug you that you didn't get Ultegra, and you're going to immediately start plotting to 'upgrade,' go ahead and buy what you really want.

Well, this gruppo makes a lot of sense financially and it meets a lot of current needs. At least no one said, "105 sucks"... so I think I will go ahead and get it, knowing full well that I may upgrade sometime in the future when the time and money is right. As long as it performs decently, that is all I really care, and 330g is not that extensive. I may sell off parts here and there and eventually upgrade and throw these on a rain bike down the road... thanks.

I rode 105 for a year or so, raced it in some Cat 5 criteriums. The gruppo works fine, even in a race.
I think there is a 3/4 lb weight difference between 105 and Ultegra.

I asked some pretty knowlegble mechanics about 105 versus other gruppos, and they have said that 105 today is a bettr gruppo than older Dura Ace for example, and that new 105 does a fine job.

new the price differnce between Ultegra and 105 is less than 100 bucks.

Id say either go for the 105 gruppo, or wait and find the same or similar deal on Ultegra...

He put ithe miles on in the last two years, training miles. He races mountain bikes, winning the world championship in Colorado in 2001 for his age group (50+). For what its worth, the pesky little guy's fine with 105.

Check my math, but just went to Shimano's website to get the reported weights for both 105 and Ultegra you might be interested to see this... Im using the same pedals, wheels and would use the same HG-72 chain for either group... check this out... The numbers below will be for 105/Ultegra (+/- difference)all weights in grams.

Component

Headset 106g/109g (+3g)
BotBracket 250/221.5 (-29.5g)
STI Shifters 495/485 (-10g)
Brake Calipers 353/334 (-19g)
Front Derail 81/81 (0g)
Rear Derail 228/221 (-7g)
Crank 654/643 (-11g)
Cassette 12-23 236/210 (-26g)

not being used, but interesting:
Front Hub 207/198 (-9g)
Rear Hub 411/410 (-1g)

Lets see, if my calculations are correct... There are 454 g in a pound... so... the total difference of 108.5 including hubs amounts to a LESS than a quarter of a pound. So... hands down... going with the 105.

Thanks for all your help!

I've had my 105 group for 7 years (replaced rings but nothing else) and I've tacked on upwards of 20K on it without a problem. New 105 is better than piece meal used combos.

good luck, and get the 105 already!!
