Tri Bikes and Bad Knees

I got my bike properly fitted this spring (can't believe I waited to get that done) and while talking with the guy I mentioned that have some issues with my knees. Before the fitting my knees almost always hurt after a ride but now I am going further and faster and have no pain or discomfort. What the guy to,d me was to stick to a road bike and avoid a tri bike because the tri bike can be hard on the knees, is this an accurate statement? Are there any other areas of the body that a tri bike can be hard on?
Thanks for the help.

It's not the tri bike per se, but the position that probably causes the problems. Most tri bikes are set up with the rider positioned more forward than is typical on a road frame. This has aero advantages for the time trial style tri events, but comes at a cost.

However, you'll note that i said "probably". That's because thousands of tri riders don't have problems with the position, so there's more to it than that. In any case, nothing succeeds like success and the fact that however he did it, the fitter solved a problem for you and that's all that matters.

I originally came from a running background but due to knee issues I went to cycling. I started in road racing and then switched to ultra marathon racing. When I switched I got a TT/Tri specific bike and have over 63,000 miles on it with no issues. I haven't had any knee issues since taking up cycling, but proper fit is important. The position on my TT/Tri bike is more forward and puts me over my cranks more but it has not effected my knees. That's my experience, but everyone is different and fine tuning a TT/Tri bike position takes a little time.

Just saw another ortho knee and shoulder expert, a sports med doc formally from a couple of pro teams. New shoulder joint set to go in Oct. 10th and should help both swim and bike. Knees are gone enough that the only resolution is replacement so I feel the pain whether swimming, biking or WALKING even with bracing on. Can't jog for much distance and running is totally out.

As far as TT bike and pain, suggest you test ride one a distance and exert effort as you might in a tri. Different pedal stroke involved so might-might not result in discomfort with only you on a bike telling for sure. In the mean time, get on your road bike with saddle adjusted forward and butt on tip then go riding. Not exactly a TT but will get a feel of the positioning and knee pressure application.

After shoulder heals will set sights for another Ironman.
