You hung like a T-rex Ed?

I got a random question/thinking out loud

So my girlfriend is very tempted to splash out on the charge hob 3, but she is un-sure about the colour and (limited) 3 speed hub, so i thought she could get the s-s/fixed red (she prefers it in red) hob and put a 5 speed hub on it to get a better range of gears. I think the standard hob 3 would be fine, but she is the one spending the money and she isn't as sure.

any opinions would be grate :)

You get 256% instead of 177%, if you go with the SRF 5 (W). It basically equates to an extra gear either side. (If you dont mind the extra 1/2 kg, Alfine 8's can be found for the same price though.)

42:16 with 700x32 tyres.

SRF3
53.2"
70.9"
94,5"

SRF5
44.3"
53.3"
70.9"
94.5"
113.4"

Using a SRF5, and swapping to a 17 tooth sprocket gives 3 more usable mid gears (IMHO). With a better climbing gear, and a top gear that would actually get used (113.4" is a touch high IMO).

SRF5 (with 17t sprocket)
41.7"
50.0"
66.7"
88.9"
106.7"

That^ would be my chioce. But it depends on how much of a range you think she'll need. I personally think 54" is a big climbing gear, and that 42" would be apprieciated.
