I forgot how smooth my bike could run!

Easy to replace my old worn cog, and whisper-quiet. I’m going to order another cog from Wabi for the flipside hub as well.

Gearing up

"I love my Wabi special bought about 6 weeks ago. I must have 500 miles on it so far. Just can't stay off of it. I ride on the Pinellas county Rails to Trails trail on the Gulf Coast of Florida and there are no hills at all. The 46/18 setup that came on the bike was fine but I often felt like I wanted a bit more so a couple weeks ago i went to the 16t to give me a 2.875 ratio. This is working for me and I don't feel the need for a lower gear around here. I still can get up the ramp on the highway overpass on the trail, the only ""hill"" I have to deal with and I can get more speed when I have a tailwind or downward slope. The cog is well machined and seems to be of high quality. "
