What RedCat said. I tore mine off on the SW skidplate. Trimmed the new Extenda an inch and absolutely no problems since then. Just a straight cut and round corners a tad.....
10,000 km on K60's with no problem. I'd say 75% gravel and 25% pavement.....maybe.
Will replace rear with another K60. Front has a few more kalamitymetres left on it......
Indeed, I have 10000 km on the rear K60. However, there is still another 2 or 3 thousand km left on it. I really like the K60's but, based on Greg's experience with the Mitas, I will try them next.....
