Hi All I want ot shove a compact chainset on my scott cr1 its about 5 years old and I beleive has a hollowtech II bottom bracket
Its ultegra and so is my potential compact chai.onset
Unfortunately I can get the 175m for half price and to replace the exisitng 172.5 I would have to stump up another 50 quid
Questions are do I need to modify anyhting going for a compact ie: anyhting on the rear and would the extra 2.5ml cause me any issues ie: clearence from the ground
Thanks in advance
