I'm finally finishing my fixie project which has sat in my attic for the past eight months.
I'm putting standard drop bars on the bike, because I like having all the available hand positions, and I've stuck old Shimano RX100 brake levers, basically the exact same as the current Tiagra model stocked by Rivendell.
I could put just a front brake on the bike, but have two reasons to install a rear brake:
- cable tension from a rear brake will keep the right brake lever from rattling as I ride
- if I switch the rear wheel to a singlespeed setup I'd have more need of a rear brake
So, what would y'all say? Am I likely to get rattling? The brake levers do have a return spring of course but I think cable tension from the rear brake would make the right brake lever much less likely to rattle.
Removing the right lever isn't an option because I like the brake-hoods hand position and am using these Shimano levers because I find they have a more secure - though slightly less comfortable - spot for my hand than the Tektro levers I have on two of my road bikes.
I don't see any downside to having a rear brake on a fixie, besides a little weight and a little less simplicity.
