Thanks again to everyone, I did learn quite a lot from you all, which made this more fun than aggravation. I solved this problem with a Surly Brake hanger. Kind of a tight fit length-wise, but it works. I checked out everyone's suggestions once again before going forward, but it was

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

'Twas a time that builders used special bolts in seatpost binders. They were a socket and bolt combo that fit through holes in the seat lug tabs. One side was free to spin (the bolt side) and the other side (the socket side) had a key on the collar that fit into a slot cast into the lug to prevent

Hi Hugh, I'm curious, what are the slots on the sides of the holes where the bolt goes through, and why are the holes on opposing sides of the holes? Thanks, John On Wednesday, February 19, 2020 at 7:38:37 PM UTC-8, Hugh Flynn wrote: > > Things like this also exist - centered hanger but

Well, I hadn't thought of that, but I guess I could order a custom Rivendell with 54cm Hunqapillar geometry, maybe with an iridescent Woolly mammoth brown paint job? But I think there's a more reasonable solution, like the Surly or Paul brake hangers. ;) John On Wednesday, February 19, 2020

This is my AHH, which had Paul Racers brazed on. I used the Surly hanger at the suggestion of the builder. He told me it was the least likely to interfere with the seat lug and a lot cheaper than

Getting a longer binder bolt and using a Mafac hanger might be another solution as it bolts to the outside rather than into the slot. Like this one: https://www.ebay.com/itm/291709320587. Or get a longer bold that sticks our a little and bolt the Nitto hanger to the side. This will put the

To be fair, the Redwood was designed for sidepull brakes, so I don't think there needed to be thought about brake hangers. David On Wednesday, February 19, 2020 at 3:16:46 PM UTC-6, John Phillips wrote: > > Thanks Garth, and everybody, > > Rather than futz around trying one or two thinner

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

Hi, Yes, the outer edge of the long Nitto rear hanger nearly reaches my 27.2mm seatpost within the seat tube slot no matter what angle it hangs from the M6 bolt. It wouldn't be able to cam the slot in the seat tube open because it is already in the slot. I checked the seat tube

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

Same hardware, but the OP's bike is a Hunqapillar with a 27.2 post. I think he just got unlucky with the dimensions of the binder ears and Nitto hanger on this one, something needs to be filed down or replaced in there. -- You received this message because you are subscribed to the Google

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

Follow-on thought question : Does/did Riv use the same seat-lug (the "basic hardware/bolt-nut") - for both 27.2 **and** 26.8 seatpost-sized frames? Perhaps that's the key to the problem, that the Nitto hanger is incompatible on 26.8 frames using this lug? =- Joe On 2/19/20, Joe Bunik wrote: >

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

I believe one **possible source** of this issue **IS** the Nitto cable hanger itself -- On many Riv frames it fits "just fine" between the ears of the seatlug -- but, on some, when you tighten down the post -- it actually catches between the ears and cams the tube back open just enough to cause

Thanks Garth, and everybody, Rather than futz around trying one or two thinner hangers, I think I will go with the Paul Funky Monkey rear brake cable hanger to solve my problem. More expensive but at least it will complement my Paul Touring canti's. I really want to thank everyone

[RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

First of all, leaving off the rear brake bridges for bikes that have canti studs is just plain stupid dumb dumb dumb. Before you go about anything John you gotta know if the post stays put without the hanger. If the post still slips you have either an irregularity in the seatpost or

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

John, I think what you laid out in your initial post are the the permanent solutions. To confirm - your seatpost fits correctly and wouldn't slip if the brake hanger were not there, correct? The issue then is that the brake hanger is interfering with securing the seatpost fully. If so, filing

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

Thanks Eric, The interior of the seat tube is smooth, no problem there, but I could file away a bit on either side of the slot in the seat tube to accommodate the brake hanger. John On Wednesday, February 19, 2020 at 11:46:25 AM UTC-8, Eric Norris wrote: > > John: > > Sorry for jumping

John: Sorry for jumping into this a bit late, but I’ll just add that the mechanics I have spoken to about slipping seatposts would *never* recommend friction paste. If your post is slipping, there is something going on that shouldn’t be “fixed” with friction paste. That’s like putting a

Hi Everyone, Thank you for all your suggestions. My 27.2 Nitto S83 seatpost is snug enough in the seat tube to stay put at a given height if there is only a very, very thin film of grease, so I suppose the friction paste might work. How clean does the seat tube need to be of grease for

[RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

One really nice feature that I admire on Rivendell frames is that the "pinch" bolt for the Seat post is just a normal bolt and nut. I think I would ensure that the cable hanger is not limiting how tightly the pinch bolt is influencing the seat post. If the hanger is in conflict, I would take

Re: [RBW] Re: Advice Needed: Best Remedy for a Slipping Hunqapillar Seatpost

I third the idea of trying friction paste on the seat post to help your slipping seat post as long as it is the right size seat post. You might also try a thinner cable hanger such as a surly brake hanger since you are hitting the seat post with your Nitto brake hanger: [image: Image result

If it is a 26.8 you may be able to flex hone the ST to get a 27.2 in there (Handwringers need not apply). Also Nitto makes 27.0 posts, not sure about 27.4. Clayton Scott HBG, CA -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group. To
