Old school BMX chain tensioners, perfect for Raleigh Aero Pro
These are genuine 80's stock, from a closed down Raleigh shop that had mountains of old RALPAR bits in the stock room.

They originally had standard nuts on which we have replaced with Nylock to make them closer in style to Aero Pro originals.


    • These are 1980's stock and are almost identical to Raleigh Aero Pro Tensioners from the 80's.
    • The overall length is 47mm - the Aero Pro ones are slighlty longer at 49.5mm.
    • Repep Dia Compe M6 Nylock nut. Same thread as Aero Pro.
    • 10mm hole, same as AP.
