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
