The sleek new BioLogic Aria is one of the most comfortable performance-oriented saddles we've ridden. It has enough padding for comfort, but not so much that it will restrict movement or cut off blood flow over longer rides.

Ahhhhh! That's the reaction we usually get when people sit on our BioLogic™ Ergo saddle for the first time. We got tired of hard saddles that pressed in all the wrong places so we went and designed our own. Our Ergo saddle features a wider rear to fully support your sit bones and a recessed center channel to minimize pressure on your most sensitive parts. A patented DualDensity base, high density foam, and a proprietary DuraSoft cover with built in stretch will make you wonder why all saddles aren't this comfortable.

Min. insertion is at 4 inches or 100 mm.( Although we strongly suggest to be generous and insert at least one more inch as we feel that 4 inches is not enough due to the long seatpost.) Its 22.5 inches long ( 570 mm) and weighs 525 grams.
This is a black seatpost with Silver patent top , Sorry we dont have a picture at this moment.

How many times have you knelt on the ground and cursed under your breath as you've tried to inflate a tire with a small mini pump? If you're like us, it's been too many times to count. The PostPump is an ingenious product that integrates a powerful floor pump with a seat post. The pump is always ready to go, hidden from the elements, thieves, and your own forgetfulness. To use the pump all you do is remove the seat post from the frame, attach the valve, flip out the foot peg, and start pumping using the saddle as the handle. Go over 100psi in less than half the strokes of the best mini pumps. Brilliant! Suitable for all models 34 mm seat posts. 755 grams, 23 imches 590 mm long

Same as above.....but 27.2 mm seat posts diameter. This pump is 320 mm long

810 grams, 48 cm ( or almost 19 inches) from the bottom of this seatpost to the larger dia adjuster-ring
Suspension is a good thing - especially on small wheel bikes with high pressure tires. Our BioLogic™ seat post lets you float above the holes, bumps, and ruts in the road. The suspension mechanism is a special low-profile design to keep the folded size of the bike to a minimum. In addition to a striking forged clamp, the BioLogic™ seat post features adjustments for pre-load and side play. 34mm diameter.
