- Brand new for 2011, the Echo Trial frame.
- Features Echo's 'Spanish' BB system, which uses a large press-fit bearing - this gives a longer BB life, whilst still using a strong M15 ISIS spindle. BB is supplied with the frame!
- Large, CNC machined BB yoke increases weld contact area at this crucial join, increasing the strength of the frame.
- Neat, CNC machined horizontal dropouts spaced at 116mm feature a low-profile integrated tensioner design, as seen on the previous Czar 24" frame.
- Standard head tube (105mm long) has a large hole machined out to reduce weight.
- Top and down tube gussets at the head tube direct stress away from the ends of the tubes, improving frame life.
- Supplied with dedicated 4-bolt mounts spaced at 101mm.
- Available in brushed silver only.
- Recommended for 18:14 gear ratio and front freewheel only.
- Weight: 1.492kg (Without BB), 1.752kg (With steel BB).

The wheel base can change how a bike handles for tricks, but does the bb rise effect anything? for example, bunny hopping, spins

Hi Mike - The BB height affects a variety of things. The higher the BB, generally the more unstable the frame will be on 2 wheels as it'll raise your centre of gravity. The trade-off for this is that it makes the bike a little more manageable on the rear wheel, and because your weight is more orientated over the front it makes moves like gaps to front or ups to front easier. For spins, I prefer a slightly higher BB. If the BB is too low, then it can be harder to make the bike carve into a spin as it becomes, in effect, too stable. The key thing to remember with changing BB height is to get a stem to match. Generally, if the BB is higher you'll need a slightly higher stem to ensure your weight's more balanced on the bike, and if the BB is lower, vice versa. Thanks, Mark
