Crown for Bosch
The most careful E-bikers have already noticed that on the bicycles equipped with the new Bosch 2014 engine there are problems of reports that are too long. In fact, if the pedaling rate is slowed down in the demanding climbs, the Bosch engine significantly reduces its contribution and significantly increases energy consumption.
DOUBLE CROWN 14 + 18T or 15 + 18T THE WINNING COUPLE: In order to take advantage of the SpeedFun speed release and not having to blend on the pedals at the high speeds that it allows, we have created a 18 T double crown with 14 or 15 T.
Chain shifting can not be done with derailleurs, therefore the chain must be moved by hand if necessary.
SECOND CROWN KIT 18 T This kit is suitable for those who are already satisfied with the original series crown (for example, 15 T) and simply want to add the second 18T crown while preserving the original. This kit is NOT COMBINE with the original Haibike 16T crown.
Materials:
The crowns and the spacer ring are made of steel with double hardening treatment for a very long life.
The ring is made of cnc in Ergal
The double-finger key for the Active / Performance 2014 and Classic rings is made of stainless steel sp. 3 mm and laser engraved with the indication of the opening / closing verses of the left hand rings.
In the kits 14-18T and 15-18T two brass rings are inserted for the possible assembly on the chain spool present only on Haibike Full suspended models allowing a small right-left backlash.
