mmm drill'n 800 holes huh??? .... Well been ride'n for 30 years or so never done that... Seems that we replace the Hyfax after 2 years of riding. ( about 2400 miles and as mentioned before a pair of hyfax are about $15 ) We take out the rack, repack all the bearings, check all rails and supports for any stress fractures, replace Hyfax. Really...we take the rack out EVERY year for inpection and do what is nessary. This is the preventive maintence that you do to try and NOT have break downs out on the trail. About a 4 beer night with you buddies !!!
