For Tosspot Spazzy Hands

Arn't two brake cables too hard for one hand (an I dreaded typing every letter)? The dual-cable setup on my partner's trike doesn't require noticeably more force to operate than the single brake one on my two-wheeled recumbent, though I must admit I haven't tried to measure it - she has three normal fingers on her right hand, which is more than enough strength-wise (I often brake using just my little finger, when keeping my hand ready to change gear). Both machines are fitted with Avid BB7 disc brakes, with a 4-finger mountain-bike-style lever mounted pointing upwards on a vertical under-seat steering bar, so the two systems have most other factors in common for a good comparison. The main difference in feel between the two systems (when the BB7s are adjusted to a similar standard) is that the trike's braking is less grabby, presumably due to the unavoidable minor difference in biting point of the two brakes. This is, if anything, desirable - extremely grabby brakes being something of an acquired taste, and ICE trikes not being fussy about brake-steer. There's no shortage of braking power on the trike - a pair of BB7s on the front of a low recumbent makes for some serious stopping ability, however you operate them! I suspect that if you like the braking to be really sharp (eg, if you've got good control through a limited range of hand movement, or just a general preference) then hydraulics would allow for more precise balancing. Of course, brakes do vary - rim brakes in wet conditions can require more serious amounts of force on the lever, though careful choice of pad compound may mitigate that. If it's a problem, discs might be a good option. Kim. -- |
