They are available in 3 styles to accommodate your bike setup; standard 3/8", 3/8" with 14mm dropout adapter and 3/8" with 14mm peg adapter. Sold individually.
3/8" Direct replacement 3/8"x16tpi axle bolt. Fits 3/8" dropouts only.
3/8" w/ 14mm Dropout Adapter 3/8" axle bolt with integrated 14mm shoulder. For those looking to run Profile hubs with 3/8"x16tpi axle bolts in a 14mm dropout frame with no pegs.
3/8" w/ 14mm Peg Adapter 3/8" axle bolt with extra long 14mm integrated shoulder. For those looking to run Profile hubs with 3/8"x16tpi bolts in a 14mm dropout frame and 14mm pegs. When installing the 14mm peg bolt, make sure the shoulder of the bolt does not protrude past the inside of the drop out. If it does, you might need to add additional washers (see alternative view for proper spacing). Failure to install this bolt properly will result in damage to your hub.
