Subject: [CR] Broken DO eyelet and Rack Attachment


I'll been thinking about this broken DO eyelet, which is highly annoying, as the new Bates frame, despite being maybe 7 years old, was only beginning to see any significant use.

I was riding by the post office on the way in to work on a Saturday morning when the failure occured. As usual on the way to work, I had a large laptop in its case with extra battery pack, etc. in the Gilles Berthoud shopper pannier on the rear rack. This is a laptop with a 17" screen, so with case and all it is a pretty good load on one side of the rear rack. However, I've been commuting to work every day since June with this same load. I usually rotate bikes about every 3 to four weeks, so this is the 7th or 8th bike I've used,and Ive had no such failure on any other bike.

The one thing different about the Bates is that the rear rack attaches to the Weinmann stainless steel rear mudguard, whereas the rear racks on all the other bikes ridden are either secured by the rear brake bolts (usually the excellent and amazingly cheap Wald chromed steel rack) or in the case of the Caygill and Assenmacher, to brazeons on the seatstay. Clearly, securing the top of the rack to the mudguard is going to place some of the load in the pannier on the mudguard and that load is going to be transmitted through the mudguard stay to the DO eyelet. I recall I hit a downhill bump at pretty good speed on the way to the post office and felt a pretty good jolt. This may have been the intial incident that dammaged the eyelet. It is also significant that the eyelet failed on the same side that the laptop was carried in the pannier.

So my thought is that maybe securing the rear rack to the mudguard is not such a good idea if you intend to carry a fairly heavy load in the rear panniers. It is possible the the load transmitted through the mudguard stays can break a DO eyelet where the mudguard stay is attached. Anyone else think this is possible? Anyone else have an eyelet fail on a bike on which the rear rack was partly supported by the mudguard?
