How is your rear wheel performing and holding up during serious climbing?
When I climb steep hills* in the lowest gears of my Speed TR, the drivetrain feels a bit "flexy". The flex is sometimes accompanied by metal pinging sounds.
I don't think the pedals, cranks, chain, nor cassette could have any springy flex. That leaves just the lacing pattern of the rear wheel: 28 spokes in a half-radial pattern. The driveside is laced 2x, while the non-driveside is all radial. This means that all pedaling force is applied via just 7 spokes.Scary!
Maybe this is why the stock gearing on the TR is so tall...
* A steep hill where I noticed this: According to Google Earth, it climbs 175 feet in 1235 feet. That's a 14.1% average. Trimming the tame bottom and top... it climbs 110 in just 550 feet for a 20% average!
