Knee problems on road bike, but on the mountain bike.(7 posts)

Knee problems on road bike, but on the mountain bike.pkompath

Knee problems (tendinitis, anterior knee pain) occuring on the road, but not on the mtn. bike. Several weeks back, I posted a discussion about experiencing knee pains, and you fellas gave some good advice, and lead me to some very helpful websites. I've lessen the mileage, but still experienced some discomfort on both legs as opposed to one. This past weekend, I rode my mtn. bike, and I did not feel any pain accept for the soreness. I've been riding the mtn. bike a lot longer than the road bike, and been using the same spd/shoes setup on both bikes. The mtn. bike was never fitted professionally, nor has the road bike. The seat ht. is ok, because I do not have too much bending of the knees, and maybe, the spinning is working different muscles group. As for the road bike, I've been adjusting the seat ht. and having it lower increases the bend of the knee. I probably need to be fitted by the LBS.

I had the same problem, and when I measured the q factor(i think that is what it is called) or the distance the pedals are apart from each other, the mountain bike was over 2 cm wider. Since I used the same shoes for both, I bought road specific shoes and moved the cleats inward to make the distance equal to my mountain bike. That took care of the problem.
What are the real world trade-offs to increasing the Q Factor??surf

No! Hold it; LOWER road seat 1 inch bending is good...tempeteKerouak

Not everyone can switch from mountain to road easily.

frame angle positions your body over the BB differently.

If you are comfortable with your mtb settings, try lowering your road saddle a little. Not everyone rides with the saddle at max height. It's not about any for m of pro fit. It has to be yours...

Bending is ok.
Lower in 1 cm incrementsMisJG

A drastic (1 in) change in seat height could be just as disastrous to your knees. Change your seat height in no more than 1 cm increments until it feel better. I usually don't adjust more than 1/2 cm at a time.
ok 1" is a lot. I think in cm!! Still try low fr back knee (nm)tempeteKerouak

problem is with your hamstrings being too short.
On road bike upper body is lowered and that is causing the strain.
Answer is simple stretch you hamstrings, esp during the ride good luck
