Are the CRC ones grey market? Seems best price I can find with the current £15 off £100.
Been looking myself and they all seem to be within a few £'s of each other (not counting vouchers).
Thinking the Stealths might be retail though as unlike the normal version they all seem to be selling them with bleed kit, unless that is just because you have little choice but to bleed after fitting by the stealths design.
You could always get Evans to price match, you'll get retail version then!
Have you had a look in Germany? Bike24 & Bike Discount DE have been cheapest for me lately (not looked for a Reverb).
I just got one from CRC, it arrived in a plastic bag rather than a rockshox box, so OE I would think.
What size?
I've got a brand new spare 30.9mm 420mm Stealth for sale.
31.6. Guess it could be shimmed. What drop and price? Email in profile.
