Ordering Ultegra 6800 groupset-Help me choose specific specs for the components

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Ordering Ultegra 6800 groupset-Help me choose specific specs for the components

Hey guys,

I have a 2014 Giant Defy Composite 2 with Shimano 105 5700. I'm upgrading to 6800 11spd group set and would like help in choosing the specific specs of the components. I'm a mid level rider with 100 miles of riding a week.

Please take a look at the list below and help me out.

Thanks!

Well, much of it is matching what you have. The FD for example...just get the same style. What length are your current crankarms? Is your current crankset compact (50/34) and do you want to stick with that?

I make a living as a photographer and can't tell you how many ridicules questions I see posted by amateurs on photography forums online. But unlike you, majority of experienced photographers are helpful even if they roll their eyes while typing up some helpful info.
So please go away and tell your mom to stop call me and offering to pick out my underwear.

meh, on a scale to 1 to 10 that was a 2

what terrain will you be riding over the most?

if lost of hills then think about the compact crank and an 11-28 cassette
if mostly flats then the 53/39 and 12-25 cassette should be fine

I pretty much matched what I have now. I went with 50-34x172.5 on the crankset, and 11-28 Cassette. Thanks!

OP, we would need more info, like what are you riding now spec wise, and what do you want to change about it. Also, are you certain you have 11 speed compatible hubs?

Do you want more climbing gears, or do you want tightly spaced gears? There are many schools of thought, and much of it is very individual. For example, many folks couple a compact crank (50/34) with a wide spread cassette (11-28 or 11-32) to get the widest range. I run a compact crank with a 12-23, because I like the tight spacing. It is all individual preference.

That rear hub question is pretty important.

+1

Also I agree with the close spaced cassette recommended by Roll. You will have every gear you want in the range and plenty of both high and low.

Sure, but he just got the bike. If he doesn't like two-thirds of it...?

Wheels actually make more sense. I do those and more modest upgrades (cables and brake pads, etc.).

105 5700 is pretty darn good. Why upgrade to Ultegra 6800 11s ? it's a few grams in weight loss and add very little value.
now, if you're upgrading to Di2 that is a different story.
Most 11s upgrades change the rear from 12-25 to 11-25. I'd rather go to 12-28 for 11s cog and have more continuous gears going up to 28. the 11 is a waste unless you're a strong sprinter.
From the front chain rings I would consider a mid-compact 52-36

p.s I have Ultegra 6600 50x34 and 12-25 on one bike and Ultegra 6870 Di2 50x34 and 11-25 on the second bike. I should have gone with 52x36 and 12x28 instead

Slow down OP; you're giving us way too much information about yourself and your riding needs.

My opinion would be the compact 30/50 and since I live in the hills a the 12/28 appeals to me, currently I am geared much taller than that and never get to use my tallest gears except on descents. But, I to recommend a wheel/tire upgrade first. Plus extra time off to ride and better diet. I think you'll see a bigger gain from that.
