old trials fanatic Posted June 14, 2006 Report Share Posted June 14, 2006 (edited) Now i've done 2 trials on the B40 and slowly fettleing it as each outing brings up a list of things i want improveing / changing. The bikes a Faber framed, old model frame, B40 with Betor forks and OSSA type yokes. The "problem" i'm trying to get me head around at the moment is on steep downhill sections or on sheer drops it has a tendancy to "tuck under". I had a Fantic 240 Pro years ago that was the same. Now i was thinking of swaping the fork yokes for something with less offset, mine are 65mm, but at full compression on the forks there is only 12mm clearence between the front mudguard and the front downtube so not really worth it. I dont want to cut and reweld the frame so thats out too. Only other thing i could think of was to alter the handlebar position Now on my yokes the bars are approx 25mm infront of the headstock spindle. If i move them back and put the front bolt of the clamp through the back bolthole in the yokes the bars are exactly over the spindle. Now i know a man who can make up some adaptors so this could be done properly. Question is would moving the bars back over the spindle have an effect on the bikes tendancy to tuck under or is it just something i have to just put up with??? Looking at my Sherpa the bars are behind the spindle but then again the forks have a leading axle and the rake is shallower and now i'm getting confused as my brain hurts when i try to understand rake and trail and the effects they have. Any other suggestions would be much appreciated. Edited June 14, 2006 by Old trials fanatic Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted June 14, 2006 Report Share Posted June 14, 2006 OK...I'll type slowly because you probably can't read quickly... I have played with handlebar position on my modern bike quite a bit...going to extremes in both directions just to see what would happen, and I think that moving the handlebars would help. Just an opinion, though... Quote Link to comment Share on other sites More sharing options...
coxy Posted June 14, 2006 Report Share Posted June 14, 2006 yes moving the handlebar positon will help you as it changes your position on the bike and moving them back will help you to gain grip and will also help you to stop tucking under due to your weight been more over the back wheel hope this helps Quote Link to comment Share on other sites More sharing options...
