I hope the area fits here somewhat, because I'm not sure whether we have what more appropriate? It is here very briefly to the conversion of the rear disc brake of Haibike XDURO AllMtn RX 2015 which stock a 180mm XT disc has it. As we in another thread issues had been looking for the appropriate adapter, I would like to briefly share my findings here. There is some confusion, which adapter should now fit exactly, either the SM-MA-F180P / P2, the SM-MA-F203P / PM or the SM-MA90-F203P / PM. According Overview (adapter insert table) should in a PM7 Mount behind supposedly the SM-MA-F180P / P2. In Bike24 I have read, however. "To use a 203 mm brake disc on a 180 mm recording the frame you need the adapter SM-MA90-F203P / P" Then I think of something but then the SM-MA90-F203P / P ordered. After the adapter today arrived with the same disk the first big surprise. On the adapter packaging of SM-MA90-F203P / P is given as a front adapter! It remains unclear in technical supplement is "P203-P / PM are adapters that allow the use of 203mm brake discs on the framework that have been designed for 180mm discs." Since I was fully confused again! I then nevertheless made an attempt and the all fitted with the SM-MA90-F203P / P and behold, seemingly match. (See photos) As it stands, the lining fits on the disc without stand tall above or below. Also the brake result is significantly better than expected. Here it was said yes, a difference from a 180mm disc would hardly noticeable, but this is not so. In my weight of almost 100KG I can say that much tighter pulling the new disc and also the tires audibly rubber bremmst, which was not so fast with the old. As the larger disk accesses already much better and it remains a mystery to me why manufacturers resort for a couple of euros is not equal to the big screen. So if you want the car tag, I can say here, at Mount PM7 back you need the SM -MA90-F203P / P adapter, even when often what else is to be read in the net.
