Is anyone riding a classified gear hub on their gravel bike or is considering it? If so, could you share your thoughts on the new 11-40t casette from classified? I know this is marketed for MTB but to me this seems more appropriate on a GRoadbike.
My Gravel frame and most frames I just looked up max out at 44t for a single ring. With the 0.68 ratio you essentially have a 44,30 with 11-XX casette giving you thighter steps and a climbing gear close to or greater than 1:1 with the traditional road casettes. On my bike I have the SRAM XPLR drivetrain with a 42t chainring giving me a faster gear with the 10t cog and a lower gear with the 44t cog (compared to their road casettes).
Now enter the classified MTB 11-40t casette. To me this seems more road/gravel/bikepacking oriented as closer spacing is not really that important on a MTB imho. Pair this casette with a 52t frontring and the 11-40 casette and you have a really fast road bike with a 0.875 granny gear. Apart from bigger steps in the spacing this casettes should have been available from the start imho as it makes far more sense for the classified system than the current offerings.
The big problem to me seems to be that not many gravel frames can use such a big frontring and with a 44t up front and all this proprietary tech in the back not giving you more than closer spacing compared to XPLR I donāt know what to make of this system.
What are your thoughts and why did you go or didnāt go for the classified hub?
I didnāt think to make a screen shot when I saw 11-31, and when I checked later it was goneā¦ probably a typo while they were releasing the new stuff
@jn92 Iām going to use it for gravel, but one of the appeals was to have a tight cassette with a 1x so I think Iād rather play with chainrings than larger cassetteā¦ a 30-34 is easier than a 42-44 2.00 vs 2.06ā¦ i understand your point, but if you think about it I understand their way of offering a tighter cassette as one of the biggest complain of 1x is spacing in the backā¦
For me my biggest worry is the additional drag and its real value, as letās say itās 5% at 300W is a lot relating it to when Iām doing an intervalā¦
I really like the cassette ā¦ for a road bike. I mocked up a 10ā40 cassette based on those ratios, and I think thatād be an amazing option for a wider range cassette that sits squarely between the 10ā36 and 10ā44 cassettes.
12-31 and not 11-31 as I remembered
12-34/36 would be wonderfulā¦ letting me run a bigger front rings
@OreoCookie Iām already worried about any friction loss involved or due to the internal geared hubā¦ donāt tell about a 10tā¦ joking aside I understand the usefulness of such cassetteā¦ hopefully swapping cassettes is as easy as a normal one
Having it on my gravel bike since July, I can say itās great and Iām super happy with it
Clearly the missing integration with Sram/Shimano/Campa is a big *, but as you get used to it and itās not something itād be stopping me to recommend it to othersā¦
I havenāt had any chain drops so far even on chunky alpine gravel and I canāt tell any additional drag or efficiency loss, but honestly as long as there is an independent third party testing it Iād take their white paper with a grain of salt, even though I applaude them for being more transparent and willing to answer what people are asking since forever
For those using a 2-button setup (like the one Iāve set up above): They will be releasing an update to the app to allow to change the mappings on the fly.
Iāve also suggested them that they should offer the option to āsetā (rather than toggle) the gear with a single button setup, e.g. short/long or single/double press to set normal or reduction gear.
There is some garmin integration (you can see the battery levels, but not at the same time as shimano), which I believe is going to be improved too.
My only gripe is that you need a very small torx key to change the handlebar unit battery, which is too small for all the multi tools Iāve seen. I found out I had no battery just before the rift (at the starting point), and had to ride everything in normal gear.
One would also hope that the app (iphone, or some connect iq field) would allow changing the gear without the handlebar unit.
The ANT+ device it pairs as needs to be a LOT better. As youāve pointed out, it canāt be used/paired to if you already have Di2. Thankfully the bike I have this on doesnātā¦ yetā¦ When it does work (and doesnāt drop out) Iāll get battery level of the switch and rear axle, but wonāt show which gear itās in. Their 52(?) page manual glosses over this.
IMO they should have kept away from being an ANT+ Shifter and done their own thing for head unit integration. Ideally integration to work with D-Fly button assignment would be neat.
Iāll need a week or two to cool-off after installing the Powershift and having major issues with reliability, a messy multi-firmware update process, and being stuck in 0.7 gear on a ride where I had to stop and re-pair the axle. It all seems to be working fine with a new button battery in the bars and their latest firmwareā¦ but my initial impressions contained a lot of four letter words.
The end goal is to test their efficiency claims. If itās 99%, itāll be difficult to measure with standard equipment. If itās 96%-97% like a lot of people are claiming, itāll be possible to measure with the equipment I have. In 0.7 I can feel the difference in how smooth it feels. In 0.7 it feels like riding with a worn chain.
No issues for me. Iāve actually found a ānewā use case riding down hard the 21 bends - I basically only use that shift, as depending on the speed at which I get out of a bend, I can immediately ādrop a few gearsā to start the sprint out of the bend, then shift back as soon as I get high revs.
The new (upcoming) release of the app actually seems to implement some of the stuff (inverting buttons, using the dual setup as ātoggleā for redundancy) I suggested to them - not sure if because of those suggestions or not, but itās nice to see the app being actively worked on. Not sure if that release will have the option to change the gear from a phone (or connectIQ field), but I hope they implement that too, a depleted handlebar module battery mid-ride pretty much guarantees no more shifting (since the screws are too small for all the multi-tools Iāve seen. I end up carrying a mini screwdriver (lost the one they provide) on my saddle pack)
Any idea how to find out more about this one? I noticed they released a new version for iOS (1.3.8 to 2.5.9) but canāt find any information online if there are options to make use of this. I donāt have a Classified system yet to test, but it will be part of a new build in a few weeks and was wondering if I could ask the shop to get onto this
FYI, My shop didnāt know about how to set dual button. But as you can see from my post above itās fairly trivial once you get the stereo to mono splitter.
