Just mounted my cyclocross tires on my trek 520. What i had on last winter, won't help much with ice but i feel a tad more stable than riding slicks-and i'm riding down to 5ml race in druid tmrw-why drive? parking will be hell. Looks like biggest problem you may have with schwable is finding them in stock. I see Continental makes a winter tire as well. Ive had good luck with Connies so may go with them. Either way it is an investment. I would just keep them on my 520 as winter bike.
