In under a minute, my bike can go from tri bike to road bike for group rides. Time trial and triathlon bikes are built with seat tubes that have a far steeper / more upright angle than normal road bikes to allow riders to place their saddle further forwards (with less setback / offset) compared to the crank axle. Its possible to vary the saddle angle between the two positions, with the nose of the saddle being 1, 3, or 5 degrees lower when in the forwards position. It therefore makes sense to have the saddle further forward when riding on the aerobars and further back when using other hand positions. (Bought both the stem and seat post combo.) Given the increasing popularity of MTB dropper posts, many of which cost US$300-$450, I dont see the price as being a major obstacle. Im fine with this level of weight penalty if the products is useful and if it allows me to use a more aerodynamic position for a higher proportion of time or to be more aerodynamic in that position because then the slight weight penalty will be easily made up for with the reduced air resistance and it will make me faster overall. There is no way that the post could move by itself while riding because to get between the two positions it travels in an arc that requires it to go up first and there is also some mild mechanical resistance to the movement. Works as advertised. The change in weight distribution not only negatively affects bike handling and braking capabilities, but more importantly pinched nerves in the hands are even more likely to be a problem, which is already a major concern for many ultra-distance cyclists (see the Hand Comfort: Handlebars, Aerobars & Gloves page). First they sold me the wrong shim, problem corrected. It has lots of things going for it, but dont use it any more because I found that the forward position didnt put my saddle quite high enough and could cause knee problems. Stay up to date on events, sales and more. I recommend contacting RedShift directly, they are normally keen to help people to get the most out of their products. The 5 cm difference between the two saddle positions mimics the change in frame geometry between typical road and triathlon bikes, but this is the one thing that Id like to change. This aluminum post replaced a carbon seatpost but I didnt notice any change in comfort because tire pressure and saddle padding have far larger effects on comfort and differences caused by the frame or seapost are generally marginal and hard to detect. Note that I'm able to shift from standard to aero position using just my thighs, and I shift back and forth a few times on a ride without any issues (and I don't think I have particularly strong thighs).

Youve made this comment on my review for the RedShift Dual-position seatpost, which I see no reason why you couldnt cut down to size. In addition, the amount that the 5 cm change in saddle position makes to joint angles depends on saddle height, with the relative change being greater for someone like me who has a relatively low saddle height and slightly less for a taller person with a higher saddle. Interesting review of an innovative product. Dropper seatposts allow mountain bikers to raise and lower their saddles for different types of terrain and have become very common over the past few years. That would be very useful.

Ive seen many seatposts that have integrated suspension that are very poorly made and quickly develop play. Having less setback does require a slightly different combination of muscles though, so I expect your knee pain was more likely to be caused by that than by saddle height.
