Frankly I find it hard to accept that it is worth 4 times the price of a Trice or Kettwiesel. Their write up is short on details and long on hype. For instance, how much does it weigh? Also 32 and 53 gear options? A 32 I can see as a Schlupfed 16 (but that gives an 8 speed cassette, not a high end option these days), 53 needs some explination.
