Just a random question, fuelled by boredom, I notice that my SMGTE has a 'locking' qr skewer, ie allen key jobby, on the front wheel only, as does most Velotechnick stuff. Just wondering why, and why only on t'front. Is it
A) to stop wheel theft, as the chances of finding a suitable 20" wheel are much less favourable than a 26"?
B) to keep the wheel more secure? as 20" wheels are under more strain, loading, and more likely to move.?
