I'm thinking of putting a 700c rear wheel on my ice sprint, at the moment I ride on a 26". I,ve noticed a lot of faster trikes have 700c rear, l was just wondering what the pro's & con's would be putting one on my trike.
Key question .......do you wish to carry luggage via a rack and panniers and how much do you weigh
If you change the rear ......which looks like a simple tempting mod
....you will need to consider changing the front wheels or the handling will be all over the place @!#$%
For example the ICE VTX 700 rear 28x622fronts are 18x406
VTX PLUS has 700 rear 23x622 fronts are 23x406
Look close at the VTX and you will find the front seat mount is lower than the Sprint series
Whilst your at it .......the higher cornering G loads .......that you will soon discover !
Will result in serious thoughts about a bucket sea shell as offered by ICE and of course used by Windcheetahs
If you wish to improve the Sprint .........a quick diet will help ........don't overlook the chain weight (probably the simplest mod but often overlooked )
These so called quick machines do not fold ......hence a further weight saving
I have two examples of " lean and mean trikes " to show it can be done and has been done years ago .
One is a Custom built ICE Trike built in 2003 (the bar end shifters have been machined down and all the fixings are Ti or Ali ) and weighs less than a VTX !
Two is a 1992 Windcheetah carbon free and yet lighter than the 2016 Spezi show model
one clue how it achieves this
........ the casting are machined on the outside rather than rough sand cast finish ....to save weight !
Pop a picture up of your current setup and confirm the mechanical spec and I might be able to suggest suitable mods .
Food for thought ?
