thanks Mark, it was no accident. I spent 6 months deciding how to put a front bag on the bike and considered every possibility I could turn up - Ostrich bag with bar clamp, Thule rack, OMM Sherpa. Again, this is a frame with no bosses for anything - not even a fork crown brake-bolt hole. (I

I think this is all a good reminder that you have to check your stuff every now ant then. Safety warnings and weight limits are just words on a page. There are things on our bikes that are worth inspecting every now and then, just for general wear and tear, where a large amount of wear and tear

[RBW] Re: Mark's/M18 failures?

there are actually no modifications to the mark's rack. They just use the rear rod bolts for mounting stays to the fork crowns. Same thing I did with Tubus LM-1 clamps on my CX frame. I did a little hand-waving engineering, or really, hand-wriggle testing - as expected, the M18 on diving

[RBW] Re: Mark's/M18 failures?

I really don't know the history of the Ocean Air/Mark's rack, but they currently sell (out of stock) the Mark's rack in both "factory configured" and "rambler mount," so your work there is not yet done. Just from reading the post linked to in the product description, it seems they made the

It is strange to me that the Hunqapillar and the Appaloosa both have fork crown mounts but there are no pictures or mention of them being used for a rack mount anywhere on the website. Not very smart people like me don't even realize they're there (until recently!). Though my hunq came installed

Re: [RBW] Re: Mark's/M18 failures?

I'm wondering something about the tongue-loop tether strap. On the Mark's rack page, the red strap is looped from the tongue over the handlebar. Wouldn't turning the handlebar add tension towards fatiguing the rack mount, but in the opposite direction of a load? Would tension on the strap impede

Let's be fair. The photos of the Mark's Rack with the red strap are relatively new, as is the warning to use one. If people need to bend the metal strip connecting the rack to the crown, the result will be varying degrees of metal fatigue, so there should also be a warning not to bend it too

I'm still not sure on the complaining of 'could have died'. Seriously? A rack breaks, which they do, and it drops down to the tire, you go over the handlebars. Much like cyclists have been doing for years.It's kinda like a front fender collapsing from a stick or even a dirty Cinzano

[RBW] Re: Mark's/M18 failures?

I think it's fair to report a diving board failure - honestly, I would thought the steel would bend fine. I agree the Mark's rack should be sturdier with an extra set of stays. The static load these racks will support is 10 times the dynamic load they will safely support, which is why they

[RBW] Re: Mark's/M18 failures?

I agree that the diving board is the weak point of the M18. I used my M18 for a while on the rear of a bike as a support for a Carradice Camper. It was actually a great fit, but the diving board eventually bent under a load of groceries and allowed the rack to start rubbing the tire. A

Re: [RBW] Re: Mark's/M18 failures?

I have a decaleur with Berthoud on M18 and I was wondering if decaleur and bag would hold rack up if the tang broke. The tombstone would havd to push the bag so far forward to get out from under it but the bag top stays on place with decaler so i would hope the rack would not rotate forward.

Re: [RBW] Re: Mark's/M18 failures?

Thanks for all that info Northof49cold. I'm a chronic rack overloader. I figured that if I broke a rack, I'd get a new one. I hadn't considered how dangerous the failure might be. I'm off to add a strap to the Nitto Mini/basket combo on my Quickbeam. My other bike has a Haulin Colin rack with

Re: [RBW] Re: Mark's/M18 failures?

I think one of the problems here is that the Mark's Rack was originally designed to support a porteur bag with a handlebar attachment. My very vague memory is that Riv was selling Berthoud bags then; my Romulus had that rack supporting one. The rack has also been presented as a saddlebag

[RBW] Re: Mark's/M18 failures?

Maybe spot welding the tang for and aft of the bolts would work, once you got it centered where you need it on your bike. I was also recommended to use a strap by an RBW employee. That's not confidence building. What puzzles me is the M18 is rated at a 17lb load the Marks is only 4 lbs. But
