Carbon Bike Frame Project: Part 1 | In search of the right design

For those who knows that now I'm keen in getting a ISP (integrated seat post) frame either carbon or titanium. Initially only did research (here & here) on the clamp-on seat post system adopted by different renowned bicycle frame makers such as Look, Scott, Giant.

Set my eyes on the Ritchey Stubby Clamp-on Seat post, as it CLAMPS ON the 31.6mm dia seat tube instead of Look which is INSERTED INTO. Didn't bother with Giant as its clamp is unique for their frame alone.


However, read much reviews stating that this piece of clamp is 100+g which does not provide much weight saving (from weight weenie). Considering that the frame already has a extra long seat tube (acting as seat post). Its weight does not justify the use of this ISP system. Well then some German guy managed to forge a clamp which offer much weight saving.

After seeing this design, i crack my head for few weeks on how to get it fabricated in Singapore (rebound centre) or Ordering it in. Both options are pretty expensive!!

Some pictures of ISP built bike to continue inspire me to seek out for the prefect ISP frame.

Titanium ISP frames just looks so gorgeous!! Imagine it being built up with white, silver and titanium colour.

Pondering about the ISP system again for a few weeks, came across this clamp while surfing pedal force website and saw this seat post clamp


Made of carbon/aluminium. Seems like a cheaper alternative compare to the 2, i considered before. BUT, pedal force is not selling this piece separately.. Disappointed, my lead somehow hit another wall.
