Using a standard fork on a G2 geometry bike
fork offset can be really quite noticeable, you are correct in that a normal offset in a G2 frame will slow the steering down, make the bike a bit more reticent to turn into corners. Having played with all sorts of offset and CSU combos (including making franken-forks) a shorter offset in a frame meant for G2 can also make the bike a wee bit more prone to tuck under on tight corners.
worth checking the fox data as well from memory i thought they were 40-44mm? dependant on model in the 26″ wheel size (may well be wrong on this, been a while since i looked)Posted 4 years ago
So, the G2 geometry fox fork on my Gary Fisher Roscoe is in need of some looking at – the inevitable stanchion wear has finally appeared, although given that I’ve done precisely ZERO maintenance of the fork since the day I bought it (25 August 09, so just a few days short of four years ago!), it’s had a good run.
The two main options are to get the fork serviced and have a new CSU fitted, or to get new forks. I reckon the cost will be about even either way, but there’s no guarantee that new forks will have the G2 geometry – or at least that new forks at the price I’m prepared to pay will have it.
From what I can see, the main difference is the fork offset – 51mm for g2 forks, and 46 for “regular” fox forks. Is that right? I understand that the shorter the offset, the slower the steering is, at least for a given head angle and fork length. Will that 5mm make a huge difference? If I go for taller forks (e.g. marzocchi tend to be taller axle-to-crown than other forks for a given travel), will I need an even bigger offset?
Or does anyone know of a good source of either cheap G2 forks, or cheap Fox CSUs?
