    Picking up a torx wrench set. What sizes are useful for bicycles?

    I hadn't realized that bicycles use torx bolts until I went to loosen a brake lever. I am going to Princess Auto to pick up something un-related to bicycles, but they have torx wrench sets. What sizes are used for bicycles? If not Princess Auto, I guess Park Makes a set just like the allen key sets (the foldable multi-wrench kit)?

    On my bike 25 is the only Torx size used. It may be different than yours.

    For this, no need to get a Park set. I have a much cheaper set i picked up and they work fine.

    There are small sets at Princess Auto for $3-$7. Both sets include a T25.

    If you do anything with Avid hydraulic brakes you'll need T25 and T10. What type of Torx sets are you looking at? It is nice to have a full range of Torx, at least in my opinion. Many of my knives have Torx hardware and it has benefited me to have a complete set.

    T5 through T30 are the only ones I've seen on a bicycle. T-25 and T-30 are by far the most common though.

    My chainring bolts are T30.

    Just get a set. You'll eventually need them for something. I like the "socket" style because I can use them with a torque wrench, and they are cheaper. I don't think I could loosen them or tighten them enough with a screwdriver-style.

    I caught these on sale for $7.99 as I recall.

    Magura bleed screw. I want to say I've seen them somewhere else as well. Not common by any means but they are out there.
