Solution for chain suck, Bosch performance line

[EddiePJ]

Are you sure that the front sprocket is not worn out. I discarded my chain device not long after making it. With the clutch engaged, the one and only time that I have had chain suck occur, was this year when I put a new chain on, but didn't replace the front sprocket. The sprocket was not overly worn, ,but changing it solved the issue straight away.

Ok, guess what happened!?

It sucked so hard that it bent the bracket!



The tape works though! Always something.

And my package is still lost it seems. I'm gonna order the same things again now!



/Edit: @EddiePJ : Yes, now that you mention it, seem like the only logical reason it is that bad now. It looks actually a little curved on the teeths. Will order a new one at the same time. Thanks man, now I have learnt at least three new things of this!

Since I broke my rear derailleur I now changed to an old one I had, an XT without clutch. This chain suck problem was REALLY bad with this
so... I had to do something, googled a little and found various solution including this thread... and... I now made an Eddie-bracket here:

Works great, but the chain rattles quite good against it, sounds bad but works good. This is the second attempt to glue it, this time with some acrylic tape that use to stick really well on everything. Hope it will last.

If I'm not mistaken that appears to be an IKEA bracket

...thanks. I ordered what to be found on BD, found a black one without side walls for 8,3 €. Will be interesting to see if it works just as good, easier to clean.

you need a off set sprocket as with that the chain will be in the tyre as will be to close to the motor.

there 90 euro from pcg.

ohh, holy ****! Seems there is a special kind for fatbikes. Well... I ordered Bosch-items from Best-Bike-Parts two weeks ago. Found it there for 99€. Since I (now) value fast shipping and have used them with good sucess I ordered from them again. What is PCG?

Hope this is the final piece in the puzzle now! Now I'll jump onto my push-MTB and will go far a very nice forrest ride, this time breaking some sweat

i cant get the cheap sprockets to work on my bike either as the ses wheel messes up the chain line tho it is fine with the 100 euro dual kit i have otherwise i need the expensive haibike ones

The haibike ones work perfectly. The likes of the connex are cheap, but cause issues with alignment and can damage case as clearance is poor.

Got my new sprocket today, looks better and works better

One note: If you are to change sprocket, also buy the nut and o-ring. Because those don't last long either and you might need to replace them also. I wonder why they can't be bundled together, well well. Cleansed them and they looked quite ok but next time I need to replace them. These things have rolled 2033 km so they have been through alot. (not that this distance is so long but it actually seems to be enough for some parts ..)

Good to hear that you are now sorted out, and able to ride again. How much did sprocket cost?

Ouch! I can buy ten Connex sprockets to fit my KTM, for the price of just that one Haibike sprocket. Very scary price.

Putting that into context. This little lot here, has just cost me less than your one sprocket.

he got no other option tho with a fat bike as no one else makes the sprockets that size and like the one piece haibike ones.

the only other one i have got to work is the dual kit but as i just use the 18t anyway just want a 18t haibike one just dont want to pay that much tho i have a 16t if anyone wants to swap.

another thing is i have not seen a 12spd haibike yet with the ses wheel pcg sell the eagle sprockets so im guessing then will also need a custom sprocket to work?

Allopes, rear mech aside, it's taken a while for me to find a photo of my simple solution to the problem.

 

[berow]

Can you tell me where you obtained this chain suck solution?
