My new Felt IA10 frameset came with an uncut steerer tube, which allows me to put some headset spacers to get the stack up to my required height. I'm not using an integrated stem/basebar option as it's currently out of my budget, and I've settled on using the stock stem with an alloy aerobar. I haven't found spacers that will sit flush with the front of the bike, and traditional round spacers will leave a lot to be desired on the front end as they leave the nose area exposed. Has anyone else used spacers on this setup before? Any recommendations for aero spacers? Or will I have to fabricate my own? Tririg Delta seems to be an option, but it might add to the hassle of charging my Di2 setup.
