I am wondering if anyone can enlighten me to what the following things are. Also if you have any
information about performance or reliability - let me know :)

1:An "Alloy cross rigid" Frame.

2:Rigid Cromo Fork

3:Shimano Tiagra with Rapid Fire - Gears

4:Alloy 52/42/30x175mm Chain

5:Alloy 'V' type Brakes

6:700c alloy double wall rims with quick release front & rear hub - Wheels

7:Adjustable 'comfort' stem.


definitions for almost any bicycle-related term you could want are available at

as to your queries directly, I interpret them below.

> 1:An "Alloy cross rigid" Frame.


> 2:Rigid Cromo Fork

Rigid, ie, not suspended. WAY preferable to a suspended fork, unless your commute takes you over
boulders and shell-holes.

(but in Kabul, they ride Flying Pigeons, which don't have springs, so...)

Cromo, ie, constructed of Cr-Mo steel.

> 3:Shimano Tiagra with Rapid Fire - Gears

Rapid-fire, ie, indexed shifting system. Shift levers are triggers integrated into the brake levers.
click one way, shift up. click another, shift down. nifty.

> 4:Alloy 52/42/30x175mm Chain

this has been cut off. last word should read 'chainset'. (which is a British usage). Front cranks
have chainrings (cogs) having 52, 42, and 30 teeth, with arms measuring 175mm in length.

> 5:Alloy 'V' type Brakes

Direct-pull cantilever brakes. usually nice stopping power and modulation, easy disengagement for
wheel changes should this be necessary.

> 6:700c alloy double wall rims with quick release front & rear hub
- Wheels

700c: ERTO number for wheels measuring 622mm in circumference, usually found on road
bicycles, hybrids.

quick-release: levers allow wheel removal without tools. Somewhat of a misnomer now that bikes have
legally-mandated 'positive wheel retention devices,' aka 'lawyer lips.'

> 7:Adjustable 'comfort' stem.

stem: handlebar/steerer extension enabling position of the handlebars forward of the steerer axis.
the goose-neck looking bit of bike handlebars that connect with the fork.

adjustable 'comfort stem': stem whose rise--ie angle of rise from the horizontal--is adjustable,
by loosening a bolt and moving in 10-15 degree intervals. Be sure bolt is tight, otherwise you
risk potentially dangerous flopping about. Or at very least a creak that will irritate the hell
out of you.

Guessing game time:

You're looking at a hybrid bicycle.
