I decided to bring my mtb and do an antenna ride. On the way I met Allan (saw his post earlier) and he said he did 3x going up antenna was outstanding. However on the first climb, I heard a crack and my saddle got loose and the whole seat post assembly disintegrated. I removed the parts that may fall: the nuts and bolts, the saddle and the other parts of the seat post assembly.
I tried to reattach the saddle whom I guessed had tools. He had but unfortunately after we thought the problem was fixed, as soon as I got on the bike the assembly collapsed again. So I followed his advice get a nut to bypass the defect: loose thread . It took me 30 minutes to get my part at Corderos bolt. It cost me P3.00 for the nut (but at least, I do not have to get a new seat post assembly or go to a machine shop)
At home it took me a while to seat the new extra nut at the seat post assembly. Now it looks fine. And I hope it wont bother me again.
