The coming winter has a bit more uncertainty than usual thanks to a strong El Nino forecast. While some may get less snow than usual, some are preparing for an epic winter. There arent many cycling brands out there that can conquer the cold like Minnesotas 45NRTH. A few months ago, 45NRTH launched some new carbon fat bike rims supporting the winter fat tire cyclist. Today, they are in the news again with an update to their popular winter riding boots, the Leather Wolvhammer and the Ragnarok.Leather WolvhammerThats right, the leather Wolvhammer is back. First introduced as a limited edition collaboration with Red Wing Leather, the OG leather Wolvhammer is still one of Zachs favorite winter cycling boots of all time due to how well the leather has broken in over the years. To be clear, the new leather Wolvhammer has nothing to do with Red Wing, and the construction of the boot is substantially different. Now featuring a large BOA dial for the lower section of the boot and a large Velcro strap on the upper, the new boot is suggested for 0 25F (-18 -4C) temperatures, though 45NRTH isnt putting an official temperature rating on the boots due to how varied personal preference can be. Just know that the Ragnarok below sits one temperature rung above the Wolvhammer for slightly warmer conditions. Leather Wolvhammer is available in sizes 38-48 and 50. In Canada, these will only be available through IBD, but in the U.S. they will also be available direct to consumers. Retail: $325 ($460 CAD)We havent tried these yet, so we cant comment for sure, but the cleat pocket appears to be closer to the inboard side of the outsole, like the last gen Wolvhammer that we tested. Thats good to prevent heel rub, but potentially not so good if youre trying to maintain the narrowest Q-factor on your fat bike. Just something to keep in mind since as soon as you put cleats on the boots to test out the position, you will likely be unable to return them.

While this product was not specified with DWR coating or any other restricted material, a supply chain issue resulted in small amounts being measured in the final product.RagnarokThe Ragnarok is still the boot for shoulder seasons with a suggested temperature range of 25F+ (-4C+). If deep winter cycling isnt your thing, but you want something to keep your feet warm and dry up until the snow flies, these could be the ticket. Ragnarok is available in sizes 36-48 and 50 and continues with a BOA fit system, but introduces a new lace path and a completely revised Velcro cuff.
