Offroad and we had a rider that used to always keep a wheel in front of everyone else. He never used to ride with us. If you got level with him- he put on speed till eventually he was going too fast for me. That annoys me as I do like to ride with someone occasionally.

Easy solution- I just mentioned to him that his rear tyre seems to be misalined on the rim. Bit later I said that I wondered if it was the rim that was out of true. Nothing wrong with it ofcourse but it did slow him down as he didn't want to damage his wheel any further.

Then another rider with too much energy for our good and we came to a crossroads in the trail.Nothing wrong with a rider going on in front as every one has to do his own ride. By the time we got to the junction he was 50 yards downhill. We turned uphill and called him back as we cycled on. Then just before he caught us- we stopped said "Sorry- it's the wrong way" and turned round. After that He stopped at every junction to let the group reform. The way we like to ride as offroad we do like to keep in contact with every rider just in case of problems.
