• Time for my next insightful proverb and lesson in building bikes up. “When you assume, you make an ass of u and me” however the “u” is also me. I assumed that because a wheel had a free hub body and not a screw on freewheel that a 10 speed cassette would fit, no problem. Oh how wrong I was.

    Got myself a sunrace 11-42t for cheap and got all giddy when it was sliding onto the free hub body no problem. Went to put the lock ring on and it didn’t even thread. Spent a little longer, thinking I might have not put the last cog on right. After a bit more fumbling, I looked up the hub and saw it was a 7 speed hub. After a little Googling I’ve realised that 7s freehubs won’t work with a 10s cassette. Anyone got any ideas how to resolve this or am I going to need to sell the wheels on and keep looking?

    In better news, managed to sort a seatpost. I never understood why all frames don’t just have a 27.2 seatpost, but 26.2 is good enough I guess. Also bought some matchy matchy bottle cage bolts to hit the free shipping amount lol

  • You can run the cassette in a ‘9-of-10’ config by ditching the 11 and 13 tooth sprockets and replacing with a 12 or 13 tooth serrated locking cog, available from Sunrace.

    This will give you 9 speeds on your 7-speed freehub, and work fine providing you set the limit screws on the rear derailleur appropriately.
