[RBW] Re: 104/64bcd Crank Question
The inside shelf is a weird Shimano lock-in thing and it can be easily filed off. - Marc On Wednesday, October 21, 2020 at 8:41:58 AM UTC-7 Coal Bee Rye Anne wrote: > I'm curious whether anyone could confirm or deny if all 104/64bcd cranks > are created equal with middle/outer chainring compatibility or whether > there are possibly some variances in spider/shelf design? > > The reason I ask... and this is purely academic at this time as I've no > real need/time/expense to fully pursue any projects right now... is that I > just now became aware of a spec/design feature of my Deore LX FC-M571 > Octalink triple crank which actually has a different shelf height on the > middle and outer part of the 104bcd spider. > > I came to this realization after recently cleaning and mocking up my spare > crank for a potential 2021 build.

Yes, I'm running right-side drive with a 1x system. I really hate front derailleurs on tandems, so going 1X on this one let me skip having to source tandem cranks. - Marc Pfister CC-NV -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] New Hubbuhs?
There's probably at least 11 other newborn Hubbuhs out there, here's mine: https://www.instagram.com/p/B1SaleiFUCw/ Parts highlights: 60mm G-One Speeds tubeless on Velo Orange Voyagers DT rear hub, Shimano XT Dyno front 1x10 SLX, will probably switch to 1x12 NX once we figure out the gearing range VO Granola bars Still needs a real shakedown ride but I think this is going to be an excellent bike. Only slight bummer is that the front top water bottle mount is useless on the size small frame because of the lower top tube.

Compass sound great, but am concerned re > flats/durability. Considering WTB Horizon 47 and Panaracer GravelKing 48. My current not-a-hubbuh tandem has the GravelKing 48s on it, running tubes with tubeless sealant. This bike probably sees at least 75% of its mileage on dirt roads in goathead country. I have not had a single flat or cut in the past year. The upcoming Hubbuh is going to run 60mm Schwalbe G-One Speeds tubeless. This tire only comes in blackwall, but there's a 50mm non-tubeless version available in tanwall. WTB has a 50mm version of the Venture coming out, and there's a tubeless tanwall version. Similar but slightly skinnier is the 47mm Teravail Cannonball, which is available in tubeless tanwall version too. - Marc Pfister Windsor CO -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Anyway, it works! > Bob, If you don't plan to mount a rack but would like have a 50mm rack-style dyno tail light, I have an adjustable design for a light bracket that mounts to the rack bosses. You can configure the model to fit your bike, download it, and send the model to be 3d printed: https://www.thingiverse.com/thing:3091821 and https://www.thingiverse.com/thing:3093032 One has the bracket arms parallel to the face of the light. The other has arms at 45 degrees to more efficiently bridge over cantilever and centerpull brake cables. I have my own 3d printer so can also assist in getting these into the hands of anyone that wants one. Just email me off-list.

It's not too fragile but doesn't feel slow. It also is easy to deal with for tubeless. The Schwalbe Thunder Burt is known to be a very fast feeling tire, much faster on pavement than it looks. But it also has decent side knobs for when you're in the dirt. - Marc Pfister Windsor CO -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

If you want a cheap DIY version, you can buy surplus M65 jacket liners for about $10. The sleeves come off easily by snipping some stitching. Some have buttons on one side, but the one I have was all button holes so I had to sew 3 buttons on one side. As a vest you probably want to size down one size. - Marc Pfister Windsor CO -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
