I’m sure we are quite a few relying on the TPA (Turbo Pad-wear Adjuster) knob of the Magura HS33 brake to ease the pain in the legs while going down steep downhill paths.
Well, I personally have killed a few knobs (the thread, actually) after having “overstressed” this little red plastic part, typically when I screw it so much that the pads will press strongly enough inwards onto the rim to allow me going downhill without having to touch the brake lever at all. Very convenient, especially in the most difficult/steep spots!
I have always found this “unexpected” use of the TPA knob very funny and attractive - even though I regreted that the part would not be made out of alloy instead of plastic.
Well, this is until yesterday, when I found this to be available.
Yeah, sure, this is a little expensive for such a little part - but I still take it as a potentially very interesting upgrade for the Magura HS33 users.
I should get mine over the next few days, will mount it on my Muni, and will report how good (hopefully) it is.
A note that these aftermarket knobs only fit on the 2005-2010 HS33 lever blades. The older 2000-2004 HS33 lever blades still uses that big red plastic knob that is available from Magrua if you need a new one.
What was the change in 2005? If you mean the change from external “star” TPA knob to the one built into the lever, then there are still loads of the earlier type on ebay. Or was the difference more subtle?
