Been offered to buy a TT/Triathlon bike. The deal seems very good but I needed to ask a few questions before I proceed with the purchase.

I pretty much dropped 40 KGS only through cycling. Previously owned a Schwinn sporterra hybrid. Recently moved countries and couldn't take my bike and I want to get back into cycling.

The triathlon bike is something I always wanted to own. But I do need to know if it's worth it. I usually ride solo, and would do about 40 kms per day in the mornings. Would a TT bike be good for this? How would it fare on steep or uphill climbs? I know it does have a steeper riding geometry but I am willing to get accustomed to it.

I am not looking to do group rides, participate competitively or even commute. Just need the bike to kill time in the morning (usually before my university lectures start) and get back into long distance cycling.

What would you guys suggest?
