Re: New bike choice - Surly disk trucker ? - 26 inch wheels - frame size ?

I don't understand why the LHT has such steep seat tube angles in the small/medium sizes. The chain stays and top tubes are of good length so why the steep seat tube angles? In contrast, Spa's Tourer and Wayfarer are 72 degrees for all sizes.

Re: Recumbent trike tyres

Duranos have stopped being made by Schwalbe, they're no longer listed in their print or online catalogues, although shops may well have stocks. What has been introduced are tubed versions of the Pro One, I've got a pair on order in 406 for my Moulton. I'm catiously optimistic they'll hit the fast r...

Re: Recumbent trike tyres

FWIW, I like the Maxxis DTH. My average commute times over 6 days fell in both directions, and fell also over the longest up hill segment of 0.9 miles. I also like the feel of the tyres. I ran them at 60psi although the minimum on the sidewall is 85psi.

Re: Recumbent trike tyres

Schwalbe Big Apple on mine. They seem to work well. I've been looking at BAs again, for my AZUB Origami. The current versions have Liteskin sidewalls and the Raceguard double nylon breaker. In that respect they are like Trykers and Racers. Where they differ is in the compound which is "Enduran...

Re: Recumbent trike tyres

I have 'GO-BIKE' tyres on the front of mine 406-50 made by Vredesteine. Got them cheap @£10 each. Been on for over 2yrs now without a "visit"! and no noticeable wear (they have a slight wavy pattern tread but basically 'slicks') Seem to be better than the M racers I had before as my Av sp...

Re: Oh no, - 107mm front fork dropouts!

I tried squeezing the fork legs together by hand as shown here,
but they were far too strong. So I tried overtightening a skewer, but they failed to set. I will consider changing the fork to another which I have though not until I've decided whether or not I shall be keeping the bike.

Re: Oh no, - 107mm front fork dropouts!

Is it worth trying to cold set them a bit closer together? Would over-tightening a skewer with the wheel out set them nearer?

Could be. I misremebered the measurement though. It's more like 105-107mm.

photos? cheers Link to photos here, https://photos.app.goo.gl/DoM6HDvpMEZULqsT6 I misremembered the measurement, it's more like 107mm. Anyhow, shown here with a Shimano 105 hub and Halo lockable skewer. The skewer it comes with has a special endcap so that when the bike is folded the cap locks into...

Oh no, - 107mm front fork dropouts!

Finally got around to looking at a 2nd hand recumbent I bought over a year ago. Thought I'd try a different front wheel on it only to find the dropouts are too wide to sit on standard QR hub axles. Also noticed there are no lawyer lips on the forks. It's a steel fork so the legs can be tightened ont...

Re: Recumbent trike tyres

Ah, but does wider mean less rolling resistance for the same amount of vertical compliance? I don't know. Do some research and you may be able to answer your own question. The answer is no in Conti GP5000 tyres between 23mm and 32mm, see section 7 in https://www.bicyclerollingresistance.com/special...

I have used them myself but they add quite a bit of weight to a trike. Eac tyre is 150g more than a Racer and then you have to factor in heavier inner tubes, maybe heavier rims too.
