queenmildew I would bring it to your local shop or frame builder to check it over. Like others have said distortion can have an effect and something could be off and we cannot tell as easily without seeing it in person. If you had a crash and especially if you had issues resultant to that crash I would want a professional to look at it in person just in case especially on a bike like that. Bridgestone RB-T are good bikes and worth having checked over.
