Ok... a couple of things.
Yes, apparently those wheels are tubeless ready, but why do you feel the need to switch? You would need more than just "tape" to seal it, but if you wanted to go that route, the local bike shop guys can help... but I do not see the need, honestly. If you keep the tires at 100 psi or so you will not have any worries about pinchflats. Punctures happen sometimes. Learn how to pay attention to the road and avoid driving through shattered bottle and such.
That saddle is a joke and you should not use something that big. They have seats set up for larger people that are profiled correctly so you do not wear through the inside of your leg on the first ride. If you are truly that heavy, carbon frame was probably not a smart choice.
That is a nice bike for sure, though! Keep riding wear the proper gear to protect your taint.
I worked in a bike shop for 13 years, so I have seen a lot of things as far a bikes are concerned. I have seen the "beach cruiser saddle on a road bike" types and have corrected that mentality. I have also watched 400lb dudes transform into 200lb powerhouses by cycling. It is a great low-impact exercise.
Invest in clipless shoes/pedals. It is far more beneficial to use them than it is to fear falling over when you come to a stop. I have raced clipless pedals on MTB and BMX... if you are about to crash, you can unclip easily. It only takes like 10 degrees of rotation.
Most importantly... you have the right to use the whole lane (at least in this state) as you are considered a vehicle... but do not do it just to do it. If you have a shoulder, use it. Don't give us a bad name :rolleyes:
