4.5 inches long is perfect to lock into grinds! The width is big enough so my drop outs are not getting ground down (may be different for other bikes though)
Sparks at night!!
have only had it for about 6 months and have been learning febles, ice picks and nose picks and shows barely any ware! I rotate mine ever now and then.
None so farOverall Review: 5/5 highly recommend, don't get alloy pegs go for these instead and spend the extra5-10 dollars you won't be disappointed.
