Pictures of your recumbent
Re: Pictures of your recumbent
I wouldn’t have said a Speed machine was any better Audax wise than a Giro 20, it’s also probably heavier. I have a Street Machine GTE and it’s heavy, but supremely comfortable. I have raced on it in standard form, with the BHPC. Recently I have fitted ( against all advice to say it can’t be done), new front forks. I have turned my 26/20 tourer, into a 26/26 ‘lighter ‘ by 1.2kg, racing ...... high racer machine for the forthcoming BHPC season. 26 “ rigid disc forks, with 1” steerer, are the rocking horse poo of the of front forks world. It’s noticeable quicker, much higher, but I am 6’2” , and I miss the front suspension, and it’s a bit more awkward in traffic , until one gets used to it. Pot holes, on the other hand , are to be avoided, as they make ones teeth clash.
Re: Pictures of your recumbent
As per the subject line, a photo would be interesting Do you have any tweaks for keeping the rear suspension under control when racing?

Re: Pictures of your recumbent
As has been mentioned the SPM is not really that speedy, depends on your audax distances. It's a decent bike for sub 100 mile runs as it is V comfortable and has good areo advantage. Over 100 miles you start to pay for the extra mass and would be better served with something lighter that depends on annular pneumatic suspension.
If you really are after an SPM and anywhere near Birmingham ...
If I had a baby elephant, I would put it on a recumbent trike so that it would become invisible.

As fitted, not tested on the track yet.
I might add, that I swapped it back to sus forks, as I was due to go on a ride with others , that would entail coming home after dark, and the 20" wheel has a dynamo, BUT I could of course just put the 20" wheel in the 26" forks, as they are all disc braked. I didn't think of that at the time. So due to swap back. Not been on Grunhilda since 11 October ride, so going to get 'bent legs back for a month, then early feb, do my 65 km loop ride with 20" sus forks, with Strava, then swap forks and wheel, and a couple of days later, do it again,just to see time / avg speed difference.Then keep it on, for the season. Apart from the lack of suspension, it is actually a more comfortable position.

Re: Pictures of your recumbent
Cheers, I’m thinking long audax, building up to LEL etc. I think you are probably right about a speed machine. The Giro is my first bent so I’ve little to compare it to. I guess I could ways sell it and t4y another, weight is definitely a thing with Audax. Do you have a Speed Machine?

like that suspension back and front -- do those big chain tubes cause much resistance ?yostumpy wrote: ↑2 Jan 2022, 7:50pm hillingdon 1 21 014 by mark tilley, on Flickr

Well done. And one of you on it, please.

Neat I thought the lacing of the front wheel was odd...until I realised I was including the gaps between the floor tiles
