Dengfu E10 Suspension/Wheel Options

[patdam]

about shock usable. i will gave you the value for my XL E10 frame, with that everybody can use calculator to appreciate his size.

space available for rear shock fully compressed is 150mm (+-1)

 

[patdam]

with 215x60 fully compressed, space available is 5mm

 

[patdam]

About the modification done on yoke to use 215x60:

original yoke width is 26.4mm. i have reduced mine to 22.5.

I have mounted 215x60, after: 1) calculation 2) test. I say "on my frame it is working". May be 216x63 also, but I don't guarantee it whitout testing. This frame is not a "piece of wood", i find it permissive and may be it have some flexibilty. It is the raison why i prefer to keeep safety margin of 5mm rather less. In any case i do not recommand to use 200x57 (may be it is these people who speak about broken frame ?)

 

[patdam]

Hi Patdam, do you know how much tall is your Durolux 29 16cm?? I'm doubting between 16 or 17 cm travel fork.

iI have setted mine in 160. Durolux 29" is easily adjustable between 150 and 170, it is only little clips to position in air chamber

OK, sort of a fess up here.

In true school boy error or in true theory not meeting reality, having measured out the 200mm shock in place in the frame and its clearance of 60mm between the seat tube and the cross bar between the top stays, one would think with a 57mm stroke you should have 3mm clearance. I thought having seen Patdams photos I had better check by letting all the air out ( I had only let 50% of the air out due to the piggy back arrangement on the DH5, where its not recommended by Fox to work the shock without pressure in it ) and seeing fully the suspension in operation. Previously with some air in, the cross piece missed by about 3mm, tick, but was that true full deflection ?

Allas its not quite true. With all the air fully out and total movement, its not so.The cross piece rotates by about 15 degrees as it goes through the 150mm range at the back, reducing as it does the theoretical clearance of 3mm to about 0.5mm. Is that enough ? Yes and no, get some mud on there and its going to be compressed.

OK how do we give it more clearance, an offset bush in the shock will give about 3mm at each end

So if you insist on using your 200mm shock as you have one sitting around as I did, then yes you can use a 200mm shock as long as its max 57mm travel, but to give yourself true mud clearance, then fit either a single offset bush or one either end to give you back an extra 3-6 mm of length and thus clearance.

Which leads nicely on to why I like the BB to be lower to terrafirma. I ride Whytes, love em, as they feel unlike virtually every other bike I have ridden, you are riding in the bike and not on the bike. Look at any Whyte and the ground clearance is always less than normal, its just one of their characteristics and once you have ridden one, its tough to ride a taller bike. Thus a shorter overall shock with comparative stroke, will give you a lower BB.

We've had a few orders for shock bushings for the E10, so I've just made a specific product for the bike on our site.

If you need shock bushings / hardware for the E10 you can find it here - Shock Bushings | Dengfu E10 Bafang

If you want offset bushings then it's just a case of noting the frame / shock models when ordering this Offset Bushings - Pair

Cheers guys!

Hi guys a few months ago i ordered a dengfu e10 large + 600motor+ 800w batt wanted to order a rockshock 160 mm 29 fork and 150mm rockshock shock on a 29 wheel front and 27 rear but i dont know what shock (size) i need to order and do i need to order shock bushings seperatly?? Im a little confused hope you guys can help me im 53y/180 cm / 100kg wont be jumping extreme

You need a shock sized 210x55 and bushings can be purchased from @Offset here: Shock Bushings | Dengfu E10 Bafang

 

[Rob Rides EMTB]

Does anyone know why Rob purchased the Rock Shox in 210x52,5mm and not the 210 x 55 mm? On the webside of dengfu the Rear Shock is 210x55mm. So what size would be good for the dengfu e10 frame?

I did purchase the 210x55

 

[Rob Rides EMTB]

No mtb parts (forks,shocks dt wheels)in stock last 2 months was it always like this or is it a corona thing

Maybe a bit more than you were intending but this *should* fit

Hi All,

Planning the same mullet setup but will use fox shock float float x2 210 55 and fox fork 38. Would you still recommend shock offset to reduce bb and increase slack...cheers

I just used stock bushings and the BB height is around 347mm and head angle of just under 64 degrees which is fine for me personally. You could experiment with bushings, they are pretty cheap if you want to give it a go.

 

[thaeber]

I would go for a Zeb and a Vivid R2C Coil - would like to know, if the 216 x 63 would fit. That would squeeze some more travel out of the frame. To compensate the effect on the rear, I would combine it with a mullet setup, Zeb 29“ on the front at 170 mm travel. The bigger dia of the front wheel would compensate the longer rear shock, angels remain at same level, only the BB would be appr. 15 mm higher. Ride more plush with more Sag. What do You think?

 

[Waynemarlow]

To fit the longer shock into the fram, one option would be to use offset bushings. At 6 mm bolts, they offer up to 3 mm adjustment per bushing, resulting in 6mm length compensation if 2 bushings are used. 8 mm more travel at the shock (63 instead of 55) , would mean appr. 20 - 25 mm more travel depending on ratio...

You may need to check on the clearance of the crosspiece at the top of the top of the rear triangle just behind the seat tube as it will get very close to touching with the longer travel. My 200 x 57 gives 0.5mm clearance at full travel with standard bushings, to give some idea. You may have to accept a higher BB and not use offset bushings.

 

[Offset]

The E10 uses 8mm bolts, so you would achieve 4mm of total e2e reduction and not 6mm.

Hy guys

Hope my two questions are not answered already. I've ordered two frames and motors (Bafang M500) for a friend and me at Dengfu.
@Rob Rides EMTB : Which crank arms did you use? We were looking to replace the standard ones but can't find anything. We wrote mails to several crank manufacters and found out, that bafang used to use the standard 10 spline mount and now changed to 12 splines. Can you help us with this? Or are those standard Bafang arms good enough anyway?

Other question: I only found this 210x50 Rockshox rear shock (D8468A - SuperDeluxe Ultimate RCT(210x50)DebonAir - Velos & Parts - ROCKSHOX - Dämpfer - Metrisch - SUPER DELUXE - AmslerShop). Do you guys think, this works as well? just add this offset bushings from offsetbushings.com?

Thanks a lot for your help and best cheers from Switzerland

You will end up with less than 140mm travel at the back as the factory shock length is 55mm travel with a 210 E2E length.

Hi guys, wich offset would you recomend for a frame size M, 44mm or 51mm. I'm planning Mullet, 27.5" 15cm rear, 29" 16cm front
I was studying how offset affects geometry but I'm not sure how to put it on the overall geometry. In theory shorter offset increases trail wich contribute to feel more confident on steps and more stable on high speed wich is good, but in some cases it would be counter-productive, so I still don't know wich offset choose
In Dengfu specs size 17 have 1220mm of wheelbase and 66º head angle with 560mm of fork length. I will use a 572mm fork length and mullet so my head angle will be arround 64.5º - 65º So... What do you think ????

 

[Niklas Kinn]

Big wheel qustion.
i want to run with mullet setup. and I have a set of Roval 29 from my former levo expert. so what would you do?

buy a Roval rims in 27.5 and rebuild my rear wheels?

buy two new DT Swiss XT 531 rims and rebuild both my wheels?


Or buy two new Dt Swiss E1900 wheels?

i have thought of the same mullet setup but will use 160mm on the front so i do not smash the geometry too much. with a rear wheel of 710mm in diameter rather than 750 it will be lowered 20mm rear. by fitting a 216/63 it will be raised 16.2mm to compensate for the 27.5 ”

it is not 1 to 1 ratio. for 55mm shock travel you have 150 rear wheel

 

[Niklas Kinn]

yes and if you divide 150mm travel by 55mm stroke then you get 2.72mm travel for every 1mm stroke. with 63mm stroke you get 171 travel. this is if the exchange is in linear. if I am wrong, you are very welcome to correct me

 

[patdam]

That i whould mean is that Travel is not the right value to calculate variation of height. it is only the shock length, in this case +6mm and not 8mm.

In add travel is not linear, because virtual pivot. theorical calculation is near reality but not exact true, careful need to be done after assembly of space available between swing arms and frame.

I have ordered the rockshox vivid coil 216x63 and hope it will be about 16mm higher to compensate for the 20mm lower 27.5 ”rear wheel. i know it is not linear in travel.

Do check on the suspension range without the coil on, you might be a tad long on the stroke and if so don't complain to us when the rear triangle hits the seat tube. But on the other hand it will be good to know if a longer shock will fit.

I will do some experiments with both 210x55 and 216x63 to see the difference then I will share my knowledge.

Nobody share his thinking regarding fork offset???

 

[patdam]

Personal choice following you use and wishes (stability/maniability) allready explained about size. personaly with long reach i prefer short offset. In add i can say that shorterner offset as been develloped for new geometries.

 

[thaeber]

Bigger fork offset reduces the fork trail for more direct handling. If you go with a slacker steering angle, it may be benfical to use a fork with more offset for sharper handling.
