Bcreid2 0 Report post Posted September 5, 2018 I was wondering if size 272 LS4 runners will fit in a size 7.5 bauer apx2 with lightspeed edge runners? This may have been discussed in the past and i apologize if it has. I have an extra pair of 272 LS4 blades but my sons skates are 7.5D Quote Share this post Link to post Share on other sites
mojo122 530 Report post Posted September 6, 2018 (edited) 7.5D should have 263mm steel. 272mm typically is size 8 and 8.5D. Look at the bottom of the holder on the rear tower. It will have the holder/runner size marked on it there. Edited September 6, 2018 by mojo122 Added holder check 1 Quote Share this post Link to post Share on other sites
