When you adapt a geared bike to single speed, and strip it down to one ring at the front, you will find that the bolts are too wide to hold down the ring onto the crank. What you need is these skinnier ones.

Choose the 6.5mm ones for single speed use.

• Fed up with creaking bolts ?
• These high quality bolts are super strong
• Chrome plated
• ​​​​​​Strong Chromoly material
• Set of 5 bolts (you get one spare if you run a four bolt crank)
