I live in Rowland heights California. I have a hybrid bike and I'm on a VERY low budget. I love riding in the mountains. But I've noticed that some of the terrain I ride on really puts a toll on my bike, even though it's a mountain based bike. I recently lost control and skidded while going downhill and broke my wrist. I'm better now and I intent to go riding again. But I would prefer to modify my bike so it would be smoother on the rocky trails. I cannot afford to buy a new better bike! I'm really low on cash. Is there any way I can make it perform better? As in adding new parts, small tweaks etc? That would not cost me alot of money?
