chupWhat can I say... a little box... doing it's job silently.
California riderGreat product by shimano. This was purchased to convert my external di2 install to internal. The actual unit is very small in size.
Mr DalglieshVery good, small enough to get up the downtube no problem and cables lock in well.
Mr St-DenisGreat little unit, fits perfectly inside the frame.
Mr HeitzmanOn one of my recent rides my bike took on quite a lot of water in to the frameand shifting remained and remains as sharp and crisp as ever. Thumbs up.
BainesExpensive way of joining 4 cables together but in typical Shimano fashion, just works and is very much a fit and forget product
