[RBW] Re: Tektro CR720 w/Marks Rack Conflicting
When I thought about a Mark's rack on the front of my Bombadil, Rivendell recommended against it (Dave). Dave told me to only use the Marks Rack if I absolutely have to. If you can use the Mini front, on any bike, absolutely that rack wins, he said. Those lower struts are load bearing. On the Mini front, they are bent, but they are also tubular steel. Bend the Marks Rack aluminum struts and they will be much weaker than if they stayed straight. On the Mini Front, the joints are welded, not bolted together, also much stronger. If it's just going to be a handlebar support it might be fine. If it's going to get a platrack bolted to it with 25lbs of stuff, or a big wald basket and a case of beer, I would worry about the strength if the struts are bent. Dave told me the top of the fork crown bolts on my Bombadil are intended to enable me to run a big rear rack on the front, not to run a Marks Rack.

Thanks for bending tips Angus, they're really helpful. Thomas your idea has me thinking . I'm going to try cutting some strips of clear chainstay protector and put those inside the fork blades where it hits. My paint is Dupont Imron, so it does chip and all , sometimes easier than one would like. But, all my bikes are missing paint all over the place so I really shouldn't worry about it. I'm a sucker for Imron metallic paints! -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Garth, Without pictures I may be visualizing this incorrectly...but, (as Robert pointed out) can you bend the lower stays in a manner similar to the mini-front rack to allow the cantilevers to open wider?

[RBW] Re: Tektro CR720 w/Marks Rack Conflicting
somewhere on youtube is a video of Mark at riv bending them with a hammer and vise, you do not need to heat them, just do it like you mean it. The vise holds them at the same time and orientation for a syncronised bend. Call riv and talk to mark or one of the guys for moral support, they may even have a bent and cut set to solve this, as they sell the bike rack and model of brakes.

[RBW] Re: Tektro CR720 w/Marks Rack Conflicting
Hey guys, thanks for the help. After a ride to clear my head and watching the video, I reconfigured and lowered the rack, with a little bending of the struts, and everything just fits! I do have one more question though, regarding the pad holders hitting the fork blades the front , which is new to me as I've always used small enough pads that they never hit the fork blades. What do you do if you have wider tires than you have clearance between the pads? I have 50.5mm there on the Bombadil. I have a set of Michelin 2 tires that I may use in the future. Just squeeze it through? Anyone using larger than 2 tires on a Bombadil or Atlantis must have come across this. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: Tektro CR720 w/Marks Rack Conflicting
After getting the CR720 on the front, I notice they I have to put the hanger quite a bit off center for it to pull evenly. The spring adjust screws help a little ,but not enough. My previous brakes had no spring adjustment and the pull was dead straight. Any ideas would be appreciated. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: Tektro CR720 w/Marks Rack Conflicting
To add a radius to the bend you can bend them over a dowel/wood broom handle. I do it in the vise ala the video except with a dowel in there too. I don't think it would be a problem in this case, but aluminum doesn't like sharp corners too much. Angus On Aug 7, 9:31 am, J.

I couldn't get the Mark's Rack to work on the front of my bike with the CR720 cantis either.

[RBW] Re: Tektro CR720 w/Marks Rack Conflicting
Really though .. this is the third brake I've tried using on the Bombadil. I was hoping to use one paired set. Right now I have a mixed set of vintage Shimano canti's on there. The canti bosses are irregular in depth, so some brakes bind when tightened on the rear. Darn quirks. Sigh . I would like to use the CR720's , as I waited a long time for polished silver ones. They've upgraded their pads to 55mm road/cross sized and nice holders, not the 72mm pin type they had. Pads and holders are # 720.12 http://www.tektro.com/02products/pads.php -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.
