Re: Any AZUB trike owners out there?

A road link would make shifting better/smother though it means the derailleur hanging a further 20/25mm lower. I don't see why, I'm only using an 11-32 cassette. The shadow derailleur has a link/axle unit and you're right, that means the derailleur hangs lower. I've now fitted a long cage SRAM X9 R...

Re: Any AZUB trike owners out there?

Got it working on the bike stand and I can use the full capacity of the derailleur. The b-screw makes a really big difference to shifting quality but it's not very precise when changing to a lower gear, you have to overshift slightly to make the transition. I've had this on uprights with Shimano 9 s...

Re: Deore RD-M592 to replace Sora RD-R3000 ?

Horndean is just up the road. I'm in Waterlooville and the combined population of Waterlooville and Horndean is now in excess of 50K I believe. You can traditionally go 2 teeth beyond Shimano derailleur specs. I'd suggest going to 36T on the cassette rather than dropping to 22T on the crankset which...

Re: Deore RD-M592 to replace Sora RD-R3000 ?

Got it working on the bike stand. The b-screw makes a really big difference to shifting quality. My problem is that with a 20" rear wheel there is a risk of damage to the RD if I get a flat. On some cogs it appears to extend beyond the wheel rim. It's a new trike so I only tested the OEM set up...

Re: Deore RD-M592 to replace Sora RD-R3000 ?

I have just weighed both mechs on the kitchen scales.R3000 is 275g, M592 is 290g. Approx lengths are 7.5 cm vs 10 cm (between the centres of the jockey wheels). Ah, so you've actually got them in your possession, excellent!! That 15gms difference in weight isn't going to worry me, especially as it ...

Re: Deore RD-M592 to replace Sora RD-R3000 ?

I'm about to do exactly this on my AZUB recumbent trike. My understanding is that Shimano 9 speed kit is mix and match. The trike has an Acera trigger shifter which I won't be changing now. Thanks for reminding me about the lack of cable adjuster on the M592, which is a shadow design. TBH I don't th...

Re: Any AZUB trike owners out there?

I'm not happy with all the chain wrap leading to a slack chain when it's parked in the small-small combo, and with an RD operating capacity limited to only around 36T. It looks to me like the extra knuckle with the shadow design might mean that the RD would no longer knock on the chainstay and give ...

Re: Any AZUB trike owners out there?

Having got the gears I wanted as well as the seat positioned the way I wanted, I adjusted the boom length and noticed that the chain was too short. When you order an AZUB you provide your height and they set the trike up to match. But I had switched to short cranks and had the seat about 3/4 of the ...

Re: Traditonal toe clips and recumbents - do they work?

Gosh, some good ideas. The Hase pedals makes me wonder if I could make some elasticated heel straps to help with foot retention. I've ordered some diagonal heel straps https://restrap.com/collections/pedal-straps/products/diagonal-straps-1 and I shall then assess whether or not additional heel strap...

Re: Traditonal toe clips and recumbents - do they work?

The answer to your question by asking another have you every had your foot run over by the trike ? If you had you wouldn't be asking the question believe me it hurts - SPDs and do them up tight No I haven't. I can think of only one occasion in many thousands of miles on a two wheeled bent using pla...

Traditonal toe clips and recumbents - do they work?

Foot retention on recumbent tadpole trikes is important to prevent injury. "leg suck" can cause horrendous injuries if your leg gets dragged under the cruciform. I have used SPDs previously but I became disenchanted with them. I would occasionally get inadvertent release (even with single ...

Re: Any AZUB trike owners out there?

Short cranks installed with 28/42/53 chainrings. The OEM crankset had all alloy rings and chainguard which is quite impressive. Nonetheless the Ultegra crankset without chainguard and short cranks is 275g lighter. I need to check and adjust all the gear changes. I am tempted to install a bar end shi...

Re: Any AZUB trike owners out there?

Sorry no photos yet. It's not been outside, it's still stuck in the living room. Some observations after putting together: the kingpin wheel axle mounts are really neat and make sense the steel handlebars which mount to a stem underneath the frame must weigh a lot the rear subframe felt very light t...
