Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

The new standard in Girth!



Deda's bars and stems even more oversized for 2011

what was wrong with the moment of inertia in 31.8?

What about the pro handlebars from Shimano?
I got a pair..the super thick top section is nice for someone with large hands. The only downside is bartape tends to be too short.

As for why, a larger OD bar can be stiffer with thinner tubes, keeping them reasonably light. Roadies want to channel Mark Cavendish after all.

Would the warranty be void if I crossed the tape limit?

Also - seems it has a Herbie theme going on.

Why the tape line? Are they afraid someone might cover up the logo?

I just need a bar that's 2 inches in diameter. I can't keep up using these small people's bars

The only fault I see here is the outlandish clamp diameter.... as the 3T ergonova bars on my roadie have widths ranging from 38 to 44cm.

this is getting ridiculous, how can a larger diameter bar be lighter than a comparable length bar of the same shape and material construction with a narrower bar diameter

no matter how thin you get the material, the larger diameter will always weigh more because there is only so thin you can go before simply leaning the bike against a wall bends the handlebars

Look at this chart over at Thomson.

27.2 dia. x 410 mm 289 g
30.9 dia. x 410 mm 263 g
31.6 dia. x 410 mm 247 g

This is because most seatposts are ovalized, like butting, it is thicker at the higher stress area and this principle is the same when it's applied to handlebars.

Butting is your friend, my friend.

XC riders use larger diameter seatposts because they are much stronger than the seatposts of a smaller size, and lighter at the same time.

I don't think the trend will catch on, though. Unless UCI changes their weight limit rule, riders will continue to use the slightly heavier bars and seatposts because they are just dead weight. Then again, they could shave off more weight with new wheels/tires/spokes etc.

First disposable razors all had one blade, then two became the new standard. Now some of them have FIVE. Are they really going to keep going? I'll start shaving when I can buy a Gilette razor with 10 blades that has a head the size of an iPod.

As for the clamp on my bars, I want 62mm or nothing.

likely much more comfortable on the hands having a larger surface area to rest on, if you ride the tops. Also they are not as ugly as the drops with flat tops.

Problem is you can't tape the tops, at least according to Deda, so you have to rely on padded gloves instead. Also, grip won't be as good. Anyways, I mostly ride on the brake hoods or drops, so it matters little to me how the tops are shaped.

What's actually preventing someone from taping the tops?

Even so, some riders will prefer the additional grip and cushioning of bar tape, and the extra stiffness could prove too punishing for slighter riders or on rough roads. However, this is just the sort of thing that should appeal to sprinters.
Even 31.8 alloy bars are rough if they don't taper down right after the clamp. I wouldn't even consider riding a 35mm bar on the road.

it's probably impossible, cause not enough tape in the world to cover these up.
