Can I claim Segwit2X with a blockchain.info wallet? I have a blockchain.info wallet, but I am not sure whether I would be able to claim segwit2x?

Thanks in advance.
You just need the private key. A wallet (irrelevant which wallet) stores your private keys. You will probably not be able to send segwit2x with the blockchain.info-wallet, but you will be able export your private keys of your blockchain.info-wallet and then you can import them into a new segwit2x-wallet.
