Skirt guard or coatguard: a device fitted over the rear wheel of a bicycle to prevent a long skirt, coat or other trailing clothes or luggage from catching in the wheel, or in the gap between the rim and the brakes; Spindle: an axle around which a pedal rotates; threaded at one end to screw into crank arms; Spoke: connects wheel rim to hub ...
The low price and ease of maintenance of rim brakes makes them popular in low- to mid-price commuter bikes, where the disadvantages are alleviated by the unchallenging conditions. The light weight of rim brakes also makes them desirable in road racing bicycles. Rim brakes require regular maintenance. Brake pads wear down and have to be replaced.
Litespeed uses 6/4 titanium, [20] which is an alloy of titanium with 6 percent aluminum and 4 percent vanadium, instead of the more-common 3/2.5 titanium. [21] It is more difficult to work with, but has a better strength to weight ratio than other available alloys. [ 20 ]

The bead seat diameter (BSD) is the diameter of the surface of the rim upon which the tire bead sits. For rims the ISO designation lists the rim's bead seat diameter and the rim's inner width, both in millimeters and separated by a cross, along with a letter code for the rim type (e.g., "C" = Crochet-type): 622x19C
1. Chocolate Fondue. Think of that fondue fountain at the buffet as Willy Wonka's sacred chocolate waterfall and river. The chocolate must go untouched by human hands, or it will be ruined.
Tubular tyres can be less safe with rim brakes on long descents because the heat generated by braking can cause the glue holding the tyre to the rim to fail. [8] Additionally, excessive heat from rim brakes an cause the tyre pressure to increase so much that the tyre can explode, [9] but this problem also applies for clincher tyres used with ...
A typical example of a tire marking according to ISO 5775-1 is: 32-597 inflate to 400 kPa. The first number (nominal section width) is essentially the width of the inflated tire (minus any tread). The second number (nominal rim diameter) is the inner diameter of the tire when it is mounted on the rim.
