BOTM: U.P. ELECTRIFIED with new SRAM AXS - part 2

Andy Kessler - 07-Feb-2019
Normally we always have about a week between our BOTM blogs, but we knew that after yesterday's intro video we'd get so many questions that I decided to brake that rule and post the beauty shots and some more tech info asap.

Most questions were about tire clearance with the new SRAM Red AXS: For 29"/700c wheels the answer is basically the same that we have on our website for our U.P./U.P.P.E.R. frame, so if it fits the frame it fits the SRAM front derailleur clearance. You can fit up to 40mm tire depending always on your rim width, actual vs claimed tire size and tire profile. We can not test all combinations even more that rims get wider every day so just make sure you have 6mm of clearance for the frame and about 4-5mm for the battery.

For 27.5/650b wheels the answer is even more difficult. On those wheels the battery still has more limitations than the frame. Most RoadPlus tires will fit but for sure not all 2.1" MTB tires. The maximum width - and really the maximum is 50mm but please note that this is with a tire that has been inflated to your riding specifications and measured about a week after you inflated the tire for the first time. Yes, they do grow over time, I had to learn that the hard way also.

Second-most asked question was about maximum range of the rear derailleur. SRAM says 33 teeth in their tech documents. You probably can pimp that with some road links but to stay on the safe side here also the number is 33.

Enough tech, enjoy the gallery...

Hi Andy; yesterday Sram released also the (not so much) new wireless Eagle AXS for MTB; that works as the XX1 Eagle, my guess (XD body - haven't looked in the details yet); do you know if it would be possible to mix & match rear mech & new axs etap road hoods to get the wider range of gears (like with Shimano di2) ???
thx!
(bike looks great!!!)

Hey Luka, while we wait for the proper reply from Andi, I saw online yesterday a 3T Exploro with exactly the set up you mention... so yes, it should be possible.
But I also heard that SRAM will have a separate announcement on Force/Rival news later in the spring ;)

Hi Luka, yes it does but will be hard to get single components as theoretically the next 3 months should be only complete group sets on the market but who knows....

Just want to share my experience running first generation etap on my U.P. with 46/36 chainrings. There is enough clearance to run 650B 48mm (Compass) tires and 700c 38mm (Compass) tires. I wouldn’t be comfortable running anything wider in either wheel size unless I added a spacer under the derailleur hanger as suggested by someone in an earlier post. This setup has worked flawlessly even without a clutch in the rear mech. Great bike and group.

Gerard, if a person is planning to run a Shimano D/A 9000 or an Ultegra 8000 series crankset on an Open Up, do you have any suggestions on good bottom brackets to use for such cranks? Regards, Bob

Hi Bob, I like the Enduro Torqtite for example. In the case of a Shimano crank, the one you need has part number BKC-0695.

Hi there: What is the smallest size chainring a person can safely run on this bike with 1X and 2X setups? Also, is that dark blue a new Open standard color or is that a custom job, and if it is a custom paint job can you tell us who did it? Thanks much, Bob

Hi Bob, this is a special paint job only done for this limited edition. Its painted in Taiwan. I have people using the 47/32 Easton crank and the SRAM 46/33 do work no problem
