Would look good on your Yates.And here they are! Nicely packed, and they appear to be very nicely made. Pivots are tight, no slop. The mechanism feels good, nice positive clicks. The shape feels good in my hand (I've never used SRAM levers, which I think these are based on, and the most modern Shimano levers I have ever used were 8 speed ultegra STI. I've used campag for years, unless just plain old brake levers. Certainly nothing this modern). The hoods have a nice feel, and also have several tabs on the inside that locate into recesses in the lever body, so they will stay put. I have to fit, adjust and actually use them of course, but for less than 50 quid I am very impressed! I plan on fitting them to the Yates with it's 7 speed deore DX and cantis. Will probably take me ages to get around to it, but I will report back...
Tempted to buy a set for my 80's Atala with 7 speed Shimano 600 tricolour.
