What are y'all using for a speedo with 21" front?

[JGore99]

I am looking for a small speedo to go on my chop but all the ones on mikesxs are calibrated for 19" front. I went up to a 21" front. What are you guys with a 21" front wheel running for a speedo? Pictures and or links are a plus!

I will be using a GPS speedometer. You have plenty of options to choose from online.

Yeah, I'm just looking for more of an old school look....

There are analog ones out there. http://www.speedhut.com/gauge_products-gauge_type-speedometer_GPS.htm

Very cool! A little out of my price range right now but maybe in the future. Thanks for the link!

The stock speedo will work fine. The speedo works of the rolling distance of the tire not the rim size. The difference between the 100/90-19 and a 3.00/21 tire isn't enough to make more than 1 or 2 mph difference in the speedo reading.

Cool! Learn something new everyday. Thanks Leo! I was just worried when it said they were for 19" fronts. This being my first bike build I wasn't sure how far off that would put it but if it's only 1-2mph then I'm fine with that.
