GG shred dogg mullet conversion!

Wanted to convert my GG shred dogg to a mullet but I needed the 0mm lower cup. Canfield made a run of these for us in need and I successfully converted my bike to a mullet all thanks to them! So happy companies like this exist! Thanks Canfield. I'll be looking your way when new bike season approaches.

Hi Matt,
Love hearing your Shred Dogg’s rocking the mullet life now! Glad we could help make it happen. Cheers to many more miles and smiles on your new setup!
