Posture Pegs afford freedom of movement by eliminating the protruding peg heads. Tuning is accomplished by means of a removable key with grip. The peg shank is a blackwood blank, tapering from 14mm at the collar to 12.5 mm at the small end, 6.3 cm in length.  It must be shaped and fit by a luthier to the existing peg hole.  Set of 2 pegs includes two shanks and two keys.  *The steel sleeve is 2 cm long, so if you want to use these pegs in a fractional cello, make sure the peg diameter is thick enough so as not to interfere.

Replacement key for Posture Peg

New Harmony's 8mm carbon fiber endpin is 20" long, weighs ~ 42 grams with a rubber cap that weighs 6 grams.  It is a one-for-one replacement for most solid metal endpins.  If you don't have calipers to measure diameter of your existing endpin, measure around the circumference of the rod.  If it's 1", the diameter is 8mm.    The tip is heat-hardened steel that can be sharpened, though it maintains its original point for a long time.  Some players report some flex compared to solid metal rods, but this varies with player movement (emoting) as well as how close you are to full extension.  *Steel carbide may not be in stock

Adjustable bridges are not ideal for setting up a cello, but they can be a lifesaver in an emergency when there is no luthier or repair person close by.  These bridges are available in 4/4 and fractional sizes, but not a range of diameters.  They have pivoting feet since cello tops vary in curvature.  That means you will be able to set your cello up, but it is not likely the bridge will be optimal in relation to your sound post and bass bar.  They are available in low, medium and high so you can try to get a suitable height for playing.  Handy to have available at summer music camps or if you travel.
