My local trails have short, steep, ascents that usually have a lot of loose "cobblestone" near the top. I was having trouble with the front tire having no purchase, so I got some bar ends. ( I am a female, short, and top-heavy, I thought using bar ends would help me with the traction problem)
Now I have great traction on the front tire while standing on climbs, but the back tire is spinning out. I give! Is there some mystery point in between that I just haven't found yet? What's the trick to this loose, cobbley surface?
