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

Ultegra 6700 vs 6800

I have a caad10 with tektrics or whatever the brake name is called, I have installed an ultegra 6700 crank - but would like to know if I should replace these brakes with ultegra 6700 or 6800?

As far as I see three differences pop up: 1. the price difference 2. the weight difference 3. the shape difference.

But can anyone give me their opinion which one to go with? I'm pretty sure performance is the same or I might be wrong...Thanks anyway.

My CAAD10 came with Ultegra 6700 brakes and it's stopping power far exceceds my expectations being a 230lb rider. Either would be a good choice, spec out very similar, and be an upgrade from Tektro's for sure. I'd probably go with the 6700's only because the color scheme should match your crank and it's always nice to see a matched set of components.

I have some mint 6700 calipers that end on a certain auction site in about 12 hours...

If you can lock up your front wheel on a descent and go over the bars, your brakes work well enough. In my opinion brakes are one of the least bang for the buck upgrades you can make. Kool stop pads will do more for you than going from Tektros to Ultegra.

true, but some peoples OCD-ness overcomes them and it MUST be done. I can get like that myself.

I understand that completely. I bought a 5.9 Madone that had the stock Bontrager direct-mount brakes. I replaced them with DuraAce 9010's because 1) they're black and match the fork at that point, and 2) the Bontragers look cheap. I guarantee you I could stop in the same distance with either.

I just meant that for strictly performance you will get more stopping power (and dollar value) out of aftermarket pads.

I'm one of those. Upgraded the stock brakes on my CAAD10 from Tektro to 105, just so the darn brakes would match the rest of the groupset. Totally worth it.

I use the noodly Cane Creek BRS-200 brakes on a bike. Whenever I need more power, I just pull the lever harder. It's cheaper.

I'd go for the 6800 brake up front at least. I have one on my bike (upgraded from 5700) and I'm very impressed with the modulation and stopping power.

IMO, it's important to change the brake cables every year. I find that braking power suffers as the cables age.

doesn't pulling harder work for all brakes?

For what it's worth on my '11 SuperSix the stock Tektro brakes worked kind of poorly, even with Koolstop pads, competent (pretty sure!) setup, cleaned rims, etc. Upgrading to 5700 in the front (which matches my drivetrain) resulted in amazingly fantastic brake performance. I think maybe the Tektros weren't really designed for the redesigned cable pull of the 5700 levers? I use my rear brake a lot less and the stock Tektro does fine there--for scrubbing a little speed in turns I was a little over enthusiastic about, and to alternate onto during long descents.

From what I understand, 6700 and 6800 are cross compatible for brakes, and 6800 is meaningfully redesigned for greater braking force. Funny enough, 6800 calipers are actually heavier than 6700 and 5700.

I'd pick between 6700 and 6800 in your case mostly on price and availability. Maybe if you ride in the rain frequently err towards 6800, but 6700 should stop really, really well.

I have 6800 everything. Replaced the Axis 2.0 brakes that came on my Roubaix with 6800 crank and brakes so everything matched. Very good brakes.

I would do the 6800's. I bought some and the price was so close IMO a no brainer.

6800 braking is awesome. Can't speak to 6700.

I replaced my perfectly good 5700 brakes with 6800. I prefer my bikes to have the entire matching groupset if possible. It’s a hobby, so it doesn’t have to make sense! Do what makes you happy.

According to Shimano tech docs BR-6800 brakes are not compatible with 6700 shifters. Strangely enough they are compatible with 5700 shifters. Now, granted these are brakes, so there can't be all that much difference.

This is true. I will be replacing perfectly good Ultegra 6800 components some day soon with Ultegra Di2 components. Why ? Because I can.

I have 6800 (complete) on my bike and it really is a huge improvement over the 6700 groupo. The brakes are much better. They now have a 2nd cantilever that really grabs! I'm just a private cyclist having no affiliation w/ Shimano, or any other companies, and after using the 6800 groupo for a yr now I can say it's great. Much better than the 6700 series. Everything Shimano said about it (the per-release hype) is true.

True. But the tektros and Cane Creek brakes aren't bad. I've got them on a couple of bikes. Campagnolo Avanti on my Pinarello. Had 6700 on my Orbea, got 6800 on my Domane. The 6800 brakes are the best I've ever used in the sense I have a better feel for them on curvy descents. I trust them more.

Had some Mafac Racer brakes on an old bike with steel rims. If the roads were wet, and those steel rims too, stopping was optional and not bloody likely.

If the OP has the scratch, he should do whatever makes him happy. Old country roads with unexpected sharp curves and steep descents deserve some really good brakes.
