I am a mtb'er, and want to buy a road bike as well. I am looking for a descent 2nd hand bike and was offered a Raleigh RC600 full 105 bike. I thought that i would be able to get a good deal on 2nd hand bikes, but it seems there are a lot of potential pitfalls. Would you thik its better to buy a lower end new bike, or keep looking for a descent 2nd hand bike?

I have been told that Raleigh was rebranded and are now being sold as Axis Bikes. Does anyone know if this is true?

Would it affect me more than two weeks before i even feel sick?

I do a minimum of 60kms every saturday and then 80 on sundays, offroad. The past two weeks i have all of a sudden just started battling. My legs feel heavy and i just cannot keep up with the group any more. Last weekend my average heart rate semmed to be normal, just no power. This week my average heart rate was slightly higher combined with less power in my legs. What could be wrong, and how do I fix it?
