Dear Editor
First congratulations for the care with which you answer readers. I come to the question: it would be possible on a sprocket 10v Veloce 12-13-14-15-16-17-19-21-23-25 going to replace a gear like the 16 with a 27 or 28 teeth? Regarding the crankset (FSA Omega Compact 110 50/34) I could change a single crown to get to 52 teeth? Or alternatively advise me what to do if I wanted to have the relationship a little longer?

Dear reader, thanks for the compliments. As many of you also is in need to adjust the crank sprocket to the compact. Find the current development metric too long uphill and downhill too short. This also depends on its level of training, which enables it to develop the wattage required to tackle the climbs with a 25/34. On the other hand its capabilities allow it to exploit a relationship longer than 12/50. Now several opsioni to solve the problem: change a bike with a more expensive but also light (at least 500-750 grams) so that I can use easily climb into the 25/34. Train more in height with the same bike, so as to achieve the same results as the previous solution. Adopt a triple crankset (FSA or Stronglight) 30/39/52 crowns, which enable it now from intercourse longer downhill and shorter in height. With this solution, however, should also change the gearbox and the front derailleur, with specific products for triple crankset. We do not recommend installing a crank on the current 52, because the jump between the two crowns is too large, exceeds the capacity of the derailleur and enables it to be a passage of fluid ratio, fast and secure. If they want a 52, then it must also match the 34 with a 36, but this solution to penalize further uphill. Could remove the pinion from 16 and add a final pinion (Marchisio) of 28, but a solution is not advice, because, again, you lose fluid and precise steps in the report. Instead I suggest you get a new sprocket assembly with material Marchisio (expensive) or Miche (cheaper). About Miche Supertype sprockets can use the good or the Primato, they still weigh less than its Veloce. This range of relationships to assemble the sprocket: 11-12-13-14-16-18-20-22-25-28 or 11-12-13-14-15-16-18-21-24 -28. In this way a relationship has more to exploit a more uphill and downhill use. Remains intact accuracy and speed in steps of relationship. Must ensure, however, rear derailleur Veloce adopting, because it is said to be compatible with 28. Do you require an medium rear derailleut, but if he can not come up short the barbell over 26, maximum 27 (11-12-13-14-16-18-20-22-24-27).
