Aedon Posted April 1, 2008 Posted April 1, 2008 I have the set-up on my new mountain bike the same as my road. When I ride with the road pedals I have no discomfort, but now that I have MTB pedals and shoes I am having serious back ache in my lower back, why? Should I lower the seat a bit?
FlyingCheetah Posted April 1, 2008 Posted April 1, 2008 Aedon, If I understand you correctly: 1. You use the same bike but with different pedals and then experience back pains. or 2. Between road bike and mountain bike you have back pains. Option 1: pedal thickness together with the shoe might differ between the road and mtb combos. This will change your seating height. Adjust accordingly. Option 2: Total seating position, handlebars might be lower in relation to the seat on the MTB causing you to lean more forward than on the road bike.
Sean Badenhorst Posted April 1, 2008 Posted April 1, 2008 The Q-Factor differs from road bikes to MTBs. That is the distance between your feet. On a MTB your Q-Factor distance is wider than on a road bike. You just can't have exactly the same set-up on a road bike and MTB. Because of the bigger Q-Factor on your MTB, your saddle will need to be slightly lower than what it is on your road bike.
Jackes Posted April 1, 2008 Posted April 1, 2008 I have kinda related problem with my hybrid i use for road. I went in to our cycleguys to check my setup and they said it is nearly perfect, but my hands go totally numb after as early as 10 - 20 km. Last year after the classic 95 km it was so bad that they were numb for weeks afterwards and I had to go see a chyropractor. hav'nt unfortunately ridden such a long distance since, but over 20 to 50 it goes dead, luckily not for days afterwards. chyropractor reconed it could be crappy stomach muscles that put to much pressure on my lower back / shoulder muscles - whatever. totally baffles me - some advice or any ideas ?
Sean Badenhorst Posted April 1, 2008 Posted April 1, 2008 Okay, I could offer some of my 'from the saddle experience' advice here, but reckon you are most likely going to find an answer to any cycling related set-up and/or injury question on cyclingnews.com.
