What Our Gearhead(R) Experts Are Saying:"I picked up the Back Cap Set after losing the original O-ring on a trail ride and it was exactly what I needed to get my Saddle Ai Alert 250 Rear back in service. The fit is perfect and having a spare cap and O-ring on hand means a lost or damaged part does not sideline the light."Replacement hardware that keeps a well-functioning light in service rather than sending it to the parts bin is exactly the kind of product worth having in the kit before you need it. The Lezyne Saddle Ai Alert 250 Rear Back Cap Set includes a replacement mounting cap and O-ring designed specifically for the Saddle Ai Alert 250 Rear, restoring a secure fit and proper weather protection when the original cap is lost or damaged. A straightforward replacement that extends the useful life of a light you already trust.
