Vitus E-Sommet VR
- Thread starter Iain at the back
- Start date
I would try the ONE UP - Its not much shorter, maybe a few mm over the Brand X, but the way the saddle is clamped puts the seat lower than on other posts, meaning your seat would sit lower at the same insertion that with a Brand X or other post. You can also restrict the travel using shims, so could have a 140mm drop for example

To be fair half the stuff in here should be in its own topic rather than in a monster general thread. Arguably this should be locked and people should start individual topics, it'd make searching way easier and keep each conversation more relevant.
I have recently got my E-Summet 19 and I love it. Just looking over it today have after my first ride the other day, and have noticed that i am missing 2 teeth from the cassette one from each of the lowest gears. What causes this? I do not remember it jumping or anything.

shit, 2 teeth missing is not good, sounds like you got some alignment issues, but even then to sheer off teeth is bad! I presume you arent shifting under power? That won’t help. Either way you need a new cassette
Have ordered a new cassette, There is a chance I was shifting under power as was getting used to it. Lesson learnt

Check the original cassette was tight as well, mine was looseHave ordered a new cassette, There is a chance I was shifting under power as was getting used to it. Lesson learnt

Did you not call Wiggle/CRC first? They'd replace that under warranty surely. I'd certainly not expect a cassette to fail so soon.

Watched that last night - great video.
Testing mine this weekend on W2 at Afan - will be interesting to see if it can last the whole trail

I didn't know that they offered it with this option. I thought that he was referring to the E7000 switch, but then I noticed that the display is different.

I tried a range test of my own a few days ago. About 50% fire road, 20% tarmac and 30% muddy. I rode mainly in Eco (+/- 70%) and Trail (+/- 25%). Over a few rides, of mixed conditions, I seem to be averaging about 16 km per bar. I weigh 85 kg with kit and I have reasonable fitness. Temps have been in the 5 to 10 C range.

BTW, the display indicated 50.1 km. It seems to over read by +/- 6% compared to rides logged on my Garmin Fenix 5. Anyone else getting this result? Is there anyway to adjust it?
Got a picture of this?
Are you sure you've not "just" noticed the lower tooth height designed in to a Shimano HG sprocket to aid upshifting?
there should be 4 of them on the 46t sprocket and on the 37T there aren't shorter teeth but the tooth profile changes.

GPS works by recording a series of waypoints and draws straight lines between these waypoints and adds them up to calculate the distance. A Garmin Fenix is a small device with a small battery so the polling time is relatively slow.. therefore as you go around a switchback etc it can poll (record a position) before it enters and a few seconds later it polls after it leaves the other side so misses off the switchback entirely. Same goes for depressions etc it misses the distance... over long twisty rides this all adds up to a surprisingly large discrepancy Vs the real distance.
Open Garmin connect and zoom in on your map you'll see it's lots of straight lines, turn on the satellite overview and you'll see it cutting corners and missing entire bits out.. especially if it loses GPS signal for a few poll points it just straight lines the points its recorded so under reports distance also civilian GPS is deliberately inaccurate and varies. A larger GPS device tends to have a bigger battery an much faster polling times so for example my Satmap reads much more accurately than my Fenix. On my satmap I can go in and add extra waypoints if needs be around switchbacks to get it reading even more accurately the distance.
If you zero both and ride along a straight flat road they should be much closer if not identical.
Ultimately I'd trust the Bike distance as it's measuring the number of wheel rotations (continuous Vs polled) which is a fixed distance (about 2.2m per rotation of a 27.5 wheel) hence accurate... if you jump or wheel spin it can affect the accuracy but its effectively insignificant. Only time it would be incorrect is if the wheel diameter is incorrect out of the gate, you fit different tyre with a much taller or smaller profile or it's badly worn down.
Anyway hope that makes sense .. a quick zoom in on the garmin map of a ride and it will be clear why the Fenix under reports the distance.

Thank you RocketMagnet, it does make some sense. I have my Fenix set to 1 second polling and thought that this would provide an accurate report of my rides. I think I will log a few rides with my Fenix and use my iPhone to log the rides directly in Strava and compare them to each other. Anyway, I am happy with the range that I am getting and bloody love the bike.
That is broken tooth’s for sure, how does the chain looks like as there must have been supplied a lot of force to do that damage?

I think you'll probably find your iPhone is worse than the Fenix. Ultimately I'd be more inclined to believe the bike recorded distance due to how it's measuring it.. For accuracy over long distances with no line of sight for lasers surveyors use a "surveyors wheel" that works on the same principal.
Did you look and zoom in on the map and see how the Garmin Fenix is calculating distance?
So I would just accept your Fenix will under report your distance and average speed etc and take the bike values as accurate.
Next time I go out i'll compare my Satmap/Fenix/Bike distances over a twisty 15 mile MTB trail and i'd bet the Bike will be the most accurate followed by the Satmap then the Fenix.
No, the 2019 e-sommet with the E7000 motor comes with the E8010 504wh battery supplied with all the other e=sommets.
Yeah. They're broken teeth. Both alu sprockets. Which cassette is it? Slx only has one alu sprocket. TBH I'd prefer none!
Okay, that's good news! ?

Why did Vitus change the stem length from 35 mm to 50mm for the 2019 E-Sommet? 
The large size of the E-sommet is much larger than the large size of my current bike (Canyon Spectral AL 2014), for example, the reach is 40mm longer. So I guess I'm replacing the 50 mm stem for a 35 mm one ASAP.

Its a Shimano SLX M7000, 11-46T, they are replacing it under warranty luckily
Did not think of checking that and after looking can't see anything that stands out.
