Take away the alloy stem spacers and move up to a great looking pair of precision cut 3k carbon fiber spacers.

 

Available in 3 different sizes in 1 1/8" steerer tube diameters. This package contains (1) 20mm spacer, (1) 10mm spacer, and (2) 5mm spacer. After years of fitting and building bikes, these are all you should need.

 

Please keep in mind that all fork mfg's with carbon steerer tubes only recommend a 40mm stack height. If you have an alloy steerer tube, stack away!!!
