Re: Short drop deralier for 20" wheel trike

The style and size of the rear derailleur will impact both the maximum size sprocket and the maximum number of teeth that it can accommodate. Look at two examples: Compare this road derailleur http://www.microshift.com.tw/en/product/rd-r42-rd-r42s/ With this MTB derailleur http://www.microshift.com....

Re: Gearing question for recumbents.

I ran 22/36/48 chain rings and 11-36 cassette on my trike. I inadvertently cut the chain a little short so that 48 on the front and 32 or 36 on the cassette would jam the derailleur into the cassette. At a minimum it would require getting off the trike and unjaming, at worst it could damage the cass...

Re: Gearing question for recumbents.

Tangled Metal, Prop your bike/trike up so the back wheel can turn freely and run through all your gears while you crank by hand. Then you'll have an idea of what gear combinations work. On my trike I ran a 48/36/22 on the front and a 10-36 10 speed on the back with a 26" wheel. I couldn't use t...

Re: Trike for person with minor cerebral palsy?

I have a cycling acquaintance who has CP and rides recumbent trikes, a Greenspeed and a fat-trike. If you're on Facebook search for Jason Forbes of Gosford, NSW, Aus. If you have reduced flexibility in your legs you may benefit from shorter cranks, for example, 155mm instead of the 170mm that is usu...

Re: Recumbent Steering - What's going on?

On an upright you move right hand forward left hand back to turn left. Looking at tiller steering (as on a recumbent recommended for me) looks like you move both hands to the right to turn left. Is this right? It looks like the grip part of the steering moves to the opposite side to the direction y...

Re: Avoiding power idler by using Alfine hub gear

I would have thought the 'noodling' you experience StephenW is more to do with the ratio you are pushing than chain ring size. For example 22x11 shouldn't give anymore noodling than 42x21, while a 42x42 or 42x36 would give more noodling than 22x11.

Re: Chain twist on hpvspeedmachine

Put a mark with a texta or white-out to see whether the chain twists a full 180 or just twists a bit as it enters the chain tube and then twists back as it comes out. The original return chain line on my trike used to cause the chain to twist out a bit and then back again - not really a problem. If ...

Have a look at this Bike Radar hack: https://www.youtube.com/watch?v=bvlrMANstn8
Uses cable ties and produces a very neat result.

Re: Chain tubes when to replace where to buy

This is probably stating the bleeding obvious, but, have you tried some hot water, hair dryer or heat gun to soften the tube?
