Gday Aber . The Trance is quoted as having either 4" (101.6 mm) or 4.2" (106.68 mm) of rear wheel travel. Having had the shock out of my Trance recently, I would say the frame and swingarm are physically just capable of making 130 mm of travel.aber said:Does anyone know if it is possible to change the travel of RP3 in Giant Trance (2006 year model)? I'd really like to change it in 130 mm!
The problem lies in the shock. I seem to remember that the standard shock dimensions for the Trance are 1.5" stroke by 6.5" eye to eye . Assuming the leverage ratio of the Trance to be 2.8:1 (4.2" travel / 1.5" shock stroke), one would need a 1.828" travel RP3 to get the 5.118" (130 mm) of travel you desire.
The next stroke size of RP3 is 2". You would thus get about 5.6" (142.24mm) of travel but also run the serious risk of the swingarm and main triangle making physical contact. These 2" stroke RP3's also have longer eye to eyes of 7.5" and 7.875", which is sure to cause other problems.
I think the only way to achieve the 130 mm travel is to find a shock from another company with a 6.5" eye to eye and about 1.8" of stroke. Either that or talk to PUSH industries or MOJO suspension for a custom RP3.
Anyway, I entirely agree, a 5" (127 mm) travel Trance would be almost perfect :thumbsup: .
