Dengfu E10 Suspension/Wheel Options

[Kiwin]

Hello,

I just received my frame from Dengfu!

I can see from E10 geometry that for all frame sizes (mine is 19"), the fork axle to crown length shall be 560.

On the market, for 29" wheels, the forks that match such axle to crown are usually 150mm travel forks :
For example :
- Rockshox Pike/Lyrik 150mm travel are given for 561 axle to crown,
- Fox 36 @150 are 562
- ...

Going to 160mm obviously add 10mm to Axle to Crown making it 571/572...

On past messages on the forum I see most of you have chosen bigger travel forks (160, 170). Am I wrong ?

I'm just wondering how important it is to match the planned geometry of the E10 ? Maybe the answer is that 10 or 20 mm won't change much.. Just want to have your thoughts ?

Every 2 cm increased fork length will decrease Your head angle / seat angle by appr. 1 degree. Fork length 580 / 170 travel: HA 65 deg, SA 73.5 deg.

 

[Kiwin]

Thanks @thaeber. I agree with that. So this means the head angle for a fork of 571mm long will be around 65.5 degrees. This is a little less than the frame was designed for, and increasing the trail.
On the image I posted, we can see that the offset is at 37.5mm. So a fork with 42 or 44mm is the closest to frame design. But forks vendors also propose 51mm, which can help reducing the trail...
What offset do you think this frame will accept the best ? what did you guys choose ?

 

[thaeber]

I slacked the HA to 64 degree at my Cheeb, front 29“ @ 180mm travel, rear with longer 216 mm shock and 27.5“ wheel. I‘m running a Mezzer fork with 44 mm offset, feeling the bike is perfectly balanced. In wet conditions, it ist sliding very neutral over both wheels.

 

[Seqlat]

Do you use asymmetrical wheels for the E10?

 

[thaeber]

You mean Mullet? Front 29“ and rear 27.5“? Yes!

 

[Waynemarlow]

You can use a shorter travel fork say 150mm with the 29er front wheel and keep as good a rolling speed through the bumps and roots + the 150mm forks seem more available second hand. + there's a whole number of very capable 150mm analogue bikes almost unused all waiting to be donor bikes at relatively low prices compared to new parts.

Sorry I'm not to big advocate of long travel where 95% of the time its not needed. If you need 170mm of travel or longer regularly then you are into gravity bikes and thats not an E10 in my view. Get that BB up too high and you into slow responding dull feeling bikes on the trail.

The other consideration is get your bottom off the seat and your knees will give you another 75mm of travel over the suspension travel, how often do you see guys going down bumpy paths still seated.

 

[thaeber]

For me the only thing better then long travel is even longer travel ?. Most of the guys denying the advantage of more travel are not capable to tune in the suspension to optimal functionality. The weight of the bike is almost the same, so why not put in more travel? Yes, the BB is higher, but You ride much more Sag, and You can dial the suspension in to give You the super plush magic carpet feeling only a long travel bike can provide. If You dont like that, and if You dont love speed even on the rughest and steepest downhills, maybe You dont need that. Otherwise, go for it. The E10 is absolutely decent and capable. IMHO.

I absolutely agree with thaeber and length matters. My analogue freeride bike is on a Fox 40 with 190mm travel. The bike is so forgiving with rought trails and smooth over everything like a carpet. It thought me how to ride steep descent and handles rough ruts and rocky terrains. Its a blast. Unfortunately, it is difficult to get hold of travel adjust DC forks now and its very low supply now. If not i would have fitted one in my upcoming E10 project.

It is your point of view. With my experience I say that E10 is a great all mountain bike in 160 travel . i find this frame mostly an enduro bike than an XC

 

[thaeber]

@dvng: Try to get a Monitou Dorado Pro. I know they are not that common, but You can adjust the travel between 200/190/180 to my knowledge. And they have the same 3 air chamber IRT system as my Mezzer fork. If You spend some time and brain into the setup, they reward You with a super plush feeling, lots of support in the mid stroke, and hydraulic bottom out if You miss the right spot for landing ?

No, asymmetrical rim

 

[thaeber]

No standard rim, DT FR 560 Alloy rim.

 

[Seqlat]

How many lenght steerer tube need to instal on L frame with 40cm stem? I don't know how much the original headsets stick out. 16.5cm is good?

 

[Kiwin]

I received my Fox Float Evol rear shock. It comes with the two mounting holes axes in parallel. On the E10 frame they should be perpendicular to each other. How do you make the rotation ? shall I just force a bit on it ?

 

[thaeber]

Turn it. Easy! ?

 

[Velu Gautam]

I need to get a shock mounting kit.

32 x 8 for frame mount, 16.5mm x8 for linkage.

@Rob Rides EMTB Do I need shock mounting kit if I am having (RockShox Super Deluxe Ultimate RCT Debon Air 210x55mm Rear Shock) for the E10?

 

[Kiwin]

Turn it. Easy! ?

Well... I guess I'll have to deflate it before that, right ? or maybe i'm just not strong enough ?

Yes. You need to deflate it, then turn it.

Yes you will as the shock is not likely to come with any mounting hardware from Rockshox.

 

[Pav09990]

I need another recomendation of drivetrain please, how many speed cassete you are using for m600/m500 is 10 speed is enough please shere your setup and opinion TIA

 

[thaeber]

10 spd. 11-46 and 32 chainring. Perfect with M500.

Hi Thaeber
Would like to know the BB height of your bike ?
(one offset bushing used ?)
Thanks

BB height is at ~358 mm, one offset bushing, 216 mm shock length, mullet wheelset, 180 mm fork. Seems high, but I run my bike with 30% SAG, and it feels great. 170 mm crankset and almost no pedal strike.

thanks!
I checked the previous threads, just need to material off 2-3mm of the hinge for installing 216x63mm shock
please advise if any other issue need to pay attention ?

No thats all. You only have to rework the upper part (see picture) of the yoke, the lower part doesnt need any rework, no contact to the seattube with 216 mm shock.

thanks thaeber!
another question is:
will the HA changed if i turn the yoke upside down?

just like Specialized Status 160 as pictures shown

 

[thaeber]

I don’t think so. The part looks symmetrical, so no effect if You turn it upside down.

 

[duncan6]

I just compared the geometry to the trek rail. From what I can see the numbers are fairly similar. I think it i were to build it is run 29 front and rear, and put a 1.5 degree Angleset headset in to change it to 64.5 degrees.

Hi, which model of Angleset should be used on Dengfu E10 ?
I can't find the suitable one for 1.5 degree.
Please advise, thanks!

 

[thaeber]

With 216 shock and 27.5“ rear wheel, one Offset bushing, 180 mm Fork and 29“ wheel at the front, the HA is at 64 degree. Perfect in my opinion.
