I have a strive 9.0 with hammerschmitt and its awesome, hopefully no chain suck for me. I have had some really bad suck with previous bikes.
The bike has worked perfectly as you would expect on any new bike. It climbs well only limited by my lack of fitness and extra weight ;-), there is no lifting of the front wheel on steep technical climbs although lifts effortlessly if you need to avoid that awkward bolder on a climb. I am still getting used to the hammerschmit attached to my bike but I can really appreciate how it works and its benefits on a rapidly changing terrain especially in a good trail centre. Its either in one gear or the other it can’t be in between. It clicks effortlessly up or down, down being the direct drive 24 chain ring up is Overdrive, the ratio is approximately 1:1.6, with a ten speed cassette you have all the gears you need. Maybe due to my lack of fitness I may swap the 24 chain ring for a 22 when I next need to replace it just to help on those extra steep technical climbs. On the other hand even on road downhill’s it rarely spins out.
