@Gee tomac No bother at all.
I have the 3C HR II on the back which it turns out was not the best call when I have the same on the front as well. The tyre is fantastic, but too grippy. I have no verifiable figures for you on by how much it affects range. But as I said in another thread, when I replaced front and rear with the Rekons, I was averaging 1-2 mph faster on a bit of trail I know well. So the Rekons are less draggy than the HR II, but that is what they are designed to be!
How about this as a suggestion? Fit a Maxxis HR II, but consider a single compound and also how about going a bit narrower? I went from 2.6" on the Rekons to 2.5" on the HR II. A small change I grant you, but I could not tell the difference on the trail in terms of ride smoothness, only in grip. Remember, it was only a
very few years ago that 2.4" tyres were considered very big tyres. So how about a HR II in 2.5" single compound Maxx Terra?[/QUOTE
Cheers for the advise , I did consider maybe dropping down in width to 2.6 wt , but read so many conflicting reviews on narrower tyres on a 40mm internal width rim. Only one way to find out , is take the plunge , I definitely want more grip on the rear .
Again once again thank you , I’ve only been a member or the forum a short while and it seems from reading different threads , you are the oracle of biking ?
