I would enter my Cleland but it's already been entered to a special month in 2012 I think, so is ineligible. Hopefully someone else has one they could enter. Maybe
@GrahamJohnWallace has one lurking in a shed somewhere?
I and other 'British School' mountain-bike owners are spoiled for choice when it comes to choosing a bike they could enter here. This is because these bikes were designed to use tyres made in Finland by Nokia, who at the time did not make any 26" tyres.
It would also be nice to see some early 650b roughstuff bikes that used French randonneur balloon tyres. Though today these bikes would be categorised as 'gravel-bikes.
Cleland used five different rim sizes but never made bikes with US 26"/ 559mm rims). Highpath Engineering mostly used the 650b or 700c sizes. Jeremy Torr's English Cycles company started making 650b bikes in 1982 but by the mid 80's they offered a 26" version of there Range-Rider model as well as a 26" specific model that they called a Metro-Trekker. Then there was the Rat/Ratus racing model with a 26" up front and a 20" on the rear.
I will need to choose just one of my bikes to enter here and I don't think one of my regularly used bikes covered in mud would be a good choice.
So my choice of clean, non 26" bikes is between:
*an un-restored 1980 650b Geoff Apps' Range Rider, that was ridden up Snowdon by Nick Crane October 1981.
*a completely restored 700c Cleland Range-Rider from 1981, photos of which were published in the first ever book on mountain bikes.
*or a 1983 Cleland Aventura that I returned to its original spec during lockdown.
A decision that can wait 'till the morning.
