@SatNavSaysStraightOn how you finding the new bike. I guess it wasn't me you saw then, mind you i did manage to avoid the worst of the rain, just a bit of drizzle like
@Mo1959 and only in it for 8 or 9 miles.
A new battery and re-linking the unit to the sensor cured that, only for the H.R. to read low for the last 15 miles or so, this is the only draw back to the R20 only 3 fields at any one time, and I need to keep an eye on the mileage, needed a minimum to have a chance with the challenge, so I will replace the battery in that as well. Then just brake blocks and a rear tyre, though that isn't urgent and i should be set for the summer well to August anyway. So I might be able to save a little toward a new bike next year, all depends on the Carleton, it needs wheels (though it has a set, rear freewheel) seat post had to destroy the old one to get it out, change the centre pull brakes so an option to upgrade the brakes on the Viking at some point, BB I have the old touring chainset that can go on it, I have either the Sora RD which if coupled up to that chainset 26 or 28/38/48 and and 8sp cassette 12-13-14-15-17-19-21-23 with the 26th front and 48th would give me a range of 29.73" to 105.2" compared with viking of 31.56" to 105.2" so almost the same.
So
BB, brakes, wheels & tyres, seat post (have a saddle but....) FD, chain and cassette and paint, bar tape £200 should well do it I think
