Would you attempt this on a hybrid?
 

A friend of mine is wanting to ride the tour de cure in July and wanting to do the 63 mile ride. Doing 63 miles will be a big enough job for me but my concern is doing it on my hybrid. With only one hand position option I worry about my hands going numb. Sometimes when we take longer rides I sometimes have to ride with just the palms of my hands on the grip ends somewhat like a road bike would be to give my hands some rest. What do you think?-Would you do it?

With bar ends to use and reminding myself to use them often, I do just fine to that distance on a flat bar.

Would road bars be better? Sure, quite possibly. But I personally have no issues doing that distance on a hybrid with ergonomic bar ends. And try out different bar ends to see how they fit your hands, too. I like these:

I have bar ends on my Trek that will give me a different hand positions, and really nice when going up hills where I can get off the seat and put power on the pedals.

I would absolutely do that on my flat bar bike. I just got a set of Ergon GC3 grip\bar end combos. They are extremely comfortable. To me, they are more comfortable than a road drop bar.

I did a group ride that distance last year on my hybrid and a few longer solo rides in years past. I'd definitely want bar ends though. Do some training rides in the months leading up to the event, working up to 50 or so miles (or more). If you know you can ride 50 miles, the prospect of riding 63 will not seem daunting.

I did the Montauk Century (100 miles) on my Specialized Sirrus LTD, with shorty carbon fiber bar ends on the flat bar. No problems whatsoever.

Lots of roadies will have you believe road drop bars are perfect for everybody (which is BS-- Every person is different), but try as I might I could never get comfortable on them. I find the flat bar + bar ends setup on my Sirrus to be far more comfortable than road drop bars.

Try out both. See what you are comfortable with.

I´ve done 300 km with flat bar & bar ends. Enough for varying hand positions. Drop bars, on longer and shorter runs, gives you the benefit of aerodynamic position when going into headwinds and over all speeding.

I did 130 miles on my FX with Butterfly bars

Can not really add anything that has not already been said, + 1 on all previous post. Richard : )

Go for it.

Get the bar-end extensions, and take frequent breaks.
My favorite riding distance is between 50 and 75 miles, and I'll do several of that length ride each year.
After 60 miles I start feeling it in my hands, and after 80 miles it can really hurt. You may need to work up to your target distance.

All these reply's are very helpfull. Does anyone make a grip w/ bar end that can be removed when not need or allowed like x racing? One thought that I had was some clamp on mtb grips, and when I wanted the bar ends just remove the outer clamp and put them on. I saw some on ebay that are just clamp on's with out grips that are reasonable.

I (credit-card) tour on a hybrid (Giant FCR2, 700 x 28, bar-ends). The only thing I would add to the previous posts is that you pump up the tires to max pressure. Ok, maybe a little higher than max. It makes a huge difference. I discovered this when I toured on 700 x 37's - at well over the stated pressure they just roll so much better.
