I had the version of the Speed Pro before the came out with Speed Pro TT. One of my happiest bike days was when I bought. Another happy day was when I sold it. I grew to hate the front suspension hub and I had issues with the spokes loosening on every ride. I got to the point I always carried a spoke wrench with me. The bike was fast but I wouldn't recommend it if you are toward the upper end of the suggested weight range.

The SDG I-beam saddle had only one option when I bought the bike and there are not that many more choices now. If you don't like the saddle, you'd have to change the entire seat post if memory serves me correctly to go to the normal style saddle. I am sure someone will correct me if this isn't still accurate.

Ultimately I got tired of the compromises I had to make for the limited speed benefit I got. I ended up buying a Swift to replace it and I've never looked back. I haven't missed it a single day since I sold it.

Maybe if I was 170-180lbs, I might have enjoyed it more. It always felt fragile to me thought I never busted anything but spokes. I thought that once the spokes bedded in that issue would go away. For me it never did. The Pantour hub on my never provided me any benefit and I had to watch the brake adjustment so that under full compression they pads wouldn't hit the tires.

If you want a really fast folder and you aren't big, this might be a good option.
