I've been rebuilding the drivetrain on my surly ECR., which I use for daily commutes trail riding and bikepacking. The original 5-arm crank was difficult to find decent chainrings that would mount on the old surly crank. The new crank holds the chain great with no slip, even though I'm running with a 9 in back at the moment. I've bashed around with it pretty extensively for the last 3 months and it shift easily and grabs the chain quickly with no slip. Highly recommend.
I read a ton of reviews about the S-PHYRE RC-902 (or 901) cycling shoe in cycling forums all over the Web. The praise was universal, but I was a bit skeptical given the $425 list price. Nonetheless, recently took the plunge when the shoe was briefly on sale at WBW. Glad I did. Fits like a custom made glove. The dual BOAs provide exquisite control of the fit, which can be independently varied to match the peculiarities of each foot. One of my feet is slightly larger than the other, so having this level of control over the fit is miraculous. Along with the dual BOAs, the wider Shimano toe box and heel grip strips make for a super-comfortable fit and riding experience. The shoes transmit power beautifully - I can hammer at >600W, or cruise at 200W with the shoes accommodating both situations with ease. And the shoes look fast just sitting on a shelf. I am a size US 10.8 on one foot and 11 on the other. I bought a Shimano size 46, and think that I would be even more suited to a size 45.5, but the 45.5 rarely shows up in any color other than black.
I recently purchased a Wahoo smart trainer from my LBS(local bike shop) and it didn't come with a cassette. My LBS told me the Shamino cassette I wanted was on back order and unavailable. Because of a medical condition I wanted to use my smart trainer right away. I checked with WESTERNBIKEWORKS and they had the cassette in stock that I was looking for and delivered it to me within a few days. I am grateful to have WESTERNBIKEWORKS as a supplier for my cycling needs.
So, after years of riding with cold wet feet I decided to give the Shimano MW501 a try. The first ride out the temperature was at 22 degrees and wet. With a wool pair of socks these shoes rocked. My feet were warm and dry, which is a first while riding for a long time. I used to put the bike up for the winter but not anymore.
Waterproof, a thin layer of flannel type of material, with wool socks they will keep ur feet warm, grippy, sturdy, made to last
Price (but you get what you pay for) and they run a size big (I wear a 13 so I ordered my typical 48, had to return them for a 47).
Bottom line. GET THEM if you are tired of cold wet feet.
