<span><span></span><span>THIS VERSION (V2) IS FOR CRANKS OTHER THAN THE SUGINO XD<br /> </span><br /> Bike Polo ALL IN ONE guard and chainring. Made in the USA! </span><br /> <br /> No more bent chainrings...<br /> <br /> <span>Available NOW!</span><a href="http://www.benscycle.net/index.php?main_page=product_info&cPath=74&products_id=3734"><br /> </a> <p><span>V2Designed for Standard 5-Arm 110bcd Cranksets</span><br /> <br /> <span>The 35 tooth ring</span> - Making some of the smallest ring sizes possible adds to the strength of the system.<br /> <br /> <span>The gear ratios</span> - a 35t chainring and the following cogs/freewheels gets you this assortment of gear inches</p> <ul> <li>12t - 78.8"</li> <li>13t - 72.7"</li> <li>14t - 67.5"</li> <li>15t - 63.0"</li> <li>16t - 59.1"</li> <li>17t - 55.6"</li> <li>18t - 52.5"</li> <li>19t - 49.7"</li> <li>20t - 47.3"</li> <li>21t - 45.0"</li> <li>22t - 43.0"</li> </ul> <br /> We wanted to fit ratios that allowed a polo player to ride to a match with a small cog on one side of the wheel, and flip it to the polo gear on the other side of the wheel after they arrive at the match.<br /> <br /> <span>CNC'd out of 7075 T6 Aluminum</span> - one of the most durable alloys available and the choice of material for many professional track racing chainrings. So you should get miles and miles and miles of use. <br /> <br /> <span>Chain Width</span>- We used the Izumi 1/8" Super V chain as the baseline width for this guard. So do you have to use the Super V? Absolutely Not, feel free to use any 9.5mm width (pin width) 1/8" chain. <br /> <br /> <span>NOTE</span>- It is no secret that chains and chainrings wear with each other. Chain stretch is the number one reason chainrings go bad. So if you want this all-in-one to last you as long as possible, change your chain every year (if not twice a year) before the chain stretch ruins the teeth. If you want to make things really easy on yourself buy a Park CC-3C Chain Wear Indicatorand check your chain frequently. <br /> <br /> <span>*Cranks not included.</span><br />
