Call them up and ask. The bike shop should always know or the manufacturer should know.

My guess is that with Redline the answer is 'no'. Redline does a piss-poor job engineering their bikes to be anything other than cheap and crappy. They just don't follow standards that already exist and they reinvent the wheel... or in your case axle... and don't even do a good job at reinventing it.

Call the shop for confirmation though.
