Nice original paint. It's great to see it saved. Dynamo bracket is an unusual feature. If you haven't got any yet, Maxxis DTH are the best 451 tyres in my experience. I run mine over pressure, at 100 psi, and have found them better than Duranos or PowerBlocks. Looking forward to seeing it completed!


I was a bit confused by your comment about running the Maxxis DTHs over pressure at 100 psi. ChainReactionCycles advertise them as rated up to 110 psi. Now they're here I see the tyre itself quotes 45-65 psi. I've emailed ChainReaction to comment. Are there any issues with running so much over the rated maximum?

Otherwise, they do look great! New images to follow once this rain stops.

Just managed to get a pair of Maxxis DTHs plus tubes for under £40 from ChainReactionCycles. These tyres are available in four 20" widths: 1 1/8", 1 3/8", 1.5" and 1.75". The first two are for 451 rims, the others for 406 rims. Vendors aren't always clear about that! After a ponder I opted for the 1 3/8 for just a little bit more air between me and perdition.

Thanks Dave. Despite its age the original paint job has an air of quality about it, and it would be a shame to trash the historic decals. Oddly, the fitted dynamo had its own bracket and didn't make use of the given one.

Just checked out the Maxxis (why don't BMX vendors speak ETRTO!?) Cheapest I can find is £40 for a pair inc p&p. There are Duranos on ebay at the moment for £35/pair. I'm trying to minimise the costs, so I expect the Duranos will win.

Went to tension the wheels today; couldn't find my spoke key. Ordered a new one on Amazon, and then immediately found said spoke key. Grrrr! Tensioned the wheels, and very pleased with the result.
