Hey everyone,

I have both a roadbike and a tribike. I've been professionally fitted for both. I find that I am the slowest climber when I am on the tribike, but I keep up with the pack on a road bike. The gears are the same on both bikes.

Is the difference simply due to geometry of the bikes and the difference in muscles that I use?

Also, a kind of off the wall poll question -- what do you wear under your biking shorts?

Ya.  Skip underwear.

I find it hard to be out of the saddle with decent balance on a tri bike.  I try to keep my out of the saddle times to a min to save the legs.

Not sure about in the saddle differences.

Yes, you got it right.  The climbing power difference between road and tri IS from position (geometry)and from the different muscles you use. 

Didn't the person doing the professional Fit notice you were wearing underwear and try and correct you?  Shame on them.

I've been playing with this (Tri bike vs Road, not the under... question)

What I've found is that on a flater course, I'm about the same speed to a bit faster on my Tri bike (with a lower HR for the same speed). On a hilly course, like moderate rollers, I'm still about the same speed on the two bikes.

On a course/route with good climbs, hands down faster on the road bike. Over a 30 mile course I like to ride, I'm 1.25 mph faster (on average) on the road bike. Now, my HR is on average higher, and I'm not ready to run afterwards. So ya, I climb better on my roadbike.

Reading into your questions, are you asking about which bike to use for group rides, training, or on tris?  For me personally, my cycling rides and training are for tris and not for other cycling events so i try to maximize the time I use my tri bike, esp. for and long distances and even on hilly rides.  This year, I've used my tri bike on all my long training rides this year, 4 centuries, and the AIDS ride (545+ miles).  Granted, it was not the optimal bike in some cases for the fastest ride (esp. on the hills.  Plus, I have to admit I was also overgeared for one nasty stretch with a Cat 1 climb), but it was optimal for my tri training.

only chamois butter under the bike shorts for me...definitely no underwear or other clothing.

thanks for your reply enginerd,

i am training exclusively for tris now, so i do try to maximize my tri bike time. i was asking why there is a difference in my climbing abilities between the 2 bikes, and from what i gather it seems to be the bike geometry, different muscle use and like you said, the gearing.

the only downside to tri bikes for me is riding with large groups -- some just dont allow tri bars...

Well if you are fast enough you won't be in the group now will you?  I know that was tacky and i am not fast so if i am on my TRI bike i will be way behind the road guys so they never know.  Oh and nothing under the bike shorts but the seat.
