I have two Aurora SLCs with about 9 k miles on one and 1 k on the other. Actual weights are 150 and 151 gm. IMO, these are great saddles if the shape works for you. It works for me.
Note that the CF rails are oval so work with the typical seatposts that clamp from the top and bottom of the rails. For seatposts that clamp the sides of the rails you need the optional oval rail clamps available from the post manufacturer.
Thanks for the info. I believe you are right about the shape of the Aurora. The Endura looks to be a bit more like a Romin or other curved saddle. I believe it also has a little more padding and a recess rather than full cut out.
I have the Aurora SLC on my road bike and I'm very happy with it. Perhaps not the same level of finish and craftsmanship as some high-end saddles, but unbeatable price/performance ratio.
I trailed the Aurora and the Endura and the two really couldn't be more different The Aurora is very flat (both front-to-back and side-to-side) with thin and quite firm padding. The Endura is significantly more padded than the Aurora and just didn't fit me right. I found the relief groove on the Endura didn't work for me, but the cut-out on the Aurora lets me do an hour plus on the trainer without a hint of numbness.
The trial program is quite reasonable -- allowing you to try up to four saddles for 10 days for $20 (which covers shipping both ways). And if you buy after that, they give you a $10 discount.
