Hebie Chainglider for SPEEDHUB 500/14 (Typ 350 SPEEDHUB)
Possible trouble with Hebie Chainglider for SPEEDHUB 500/14
With the use/mounting of a Hebie Chainglider SPEEDHUB (typ 350) one has to pay attention that parts made of plastic are unable to scratch on the surface of the hub case!
With the first series of Chaingliders scratching marks occasionally appeared on the hub case by the grinding touch of the Chainglider's rear side. In October 2006 the rear part has been modified to prevent a possible abrasion. Scratches on the surface cannot diminish the stability of the SPEEDHUB case - they' re just ugly.
Now, old rear parts of the Chainglider will be exchanged cost-free to new or altered versions by Hebie (see pdf end of page).
Exchange at your bicycle dealer only!
Permitted is the use of the Chainglider with 15, 16 or 17 tooth sprockets in combination with a 42 tooth chain wheel (Typ 350-42) or a 44 tooth chain wheel (Typ 350-44). The use of a 13 tooth sprocket with the Hebie Chainglider is not permitted due to technical reasons!
While adjusting the chain tension, please pay attention to an abrasive-free sit of the chain at the hub case and check it regularly.
While riding the bike dirt particles might easily stick in the soft plastic, which can turn into a hard, abrasive surface after a while. Due to this, deep grinding grooves can emerge. In the extreme, the hub case might has to be exchanged.
A grinding-through of the hub case is not very likely, but technically possible.
