Re: [RBW] 1x11 suggestions

[Mike Rossi]

I originally had a 122.5 BB on my post-apocalyptic Clem on steroids (lugged Susie) with 2.3 knobby’s and it was “perfect”. I switched to 2.1 GKSK’s and tried a 113mm BB, but the clearance on the granny ring was way too close for my taste(with a 7 speed cassette). I now have a 118mm BB on there and it’s “perfect” again.

But, I was on the phone with Williams & others at Riv & they wanted to know what tires I was using. I told them 2.6” & they put me on hold. Came back and consensus was to get the 122.5 with the offset. If memory serves I was wanting one of the IRD bottom brackets but they did not have one in stock that they thought would work. Some amateur pics here. I have never had a tire rub but there is not a lot of clearance. BTW, the bike is fantastic. And, I have considered the same 1x that you are looking at. But my 2x7 actually works good. <image0.jpeg> <image1.jpeg> <image2.jpeg> Sent from my iPhone On Oct 11, 2025, at 1:12 PM, Seung Vo <bshmai...@gmail.com> wrote:  Honestly I picked 113mm based on what I read on the riv website under the silver cranks section. It states “On road bikes with straight (normal) chain stays, mount it on a 107-110mm square taper BB (JIS). If your bike has bowed-out chain stays like most mountain bikes, it might need a 113mm" With your 122.5mm bb do you have loads of clearance? Do you have a photo? thank you On Sat, Oct 11, 2025 at 10:06 David Ross <dross5...@gmail.com> wrote: Also, when getting a chainring, please keep in mind that 12 speed shimano isn’t compatible with all chainrings. Wolftooth and others sell chainrings specifically for 12 speed shimano.  On Wed, Oct 1, 2025 at 10:46 AM Bryan H <bshmai...@gmail.com> wrote: Hello decided to try 1x11 on my susie build, going with a XT deore 11 speed cassette. For the derailleur and shifter would love to keep it a classic silver/polish look. Any suggestions on this? Modern derailleurs are appealing to avoid lots of chain slap however couldn't find anything with the look and performance I'm going for. Any suggestions greatly appreciated!  Bryan Walnut Creek, CA  -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
