If anyone needs chainrings bigger than normal and has difficulty finding them this might be useful. I believe they supply a few racers.

Spa Cycles do every size TA chainrings in both 130mm and 110mm up to 60 teeth.
Thats where I go for a 55t chainring.
The only trouble with that size is it's not ramped and pinned.
But I don't think any are over 53t or I've not found one above that size.

But good shout if you need bigger .......  :thumbsup:

I run 55/42/30 & 11-32 9 speed on my ICE Qnt 165mm cranks
52/42/30 & 11-32 on the XL 170mm cranks
48/36/24 & 9-32 Capreo on the Vortex fs 170mm cranks (this will change to 53/39/26 152mm cranks soon).

If you are looking for shorter cranks to help with higher cadence/spinning out, ICE sell 152mm cranks.

The Lower foot speed of the 152mm cranks compared to 165-175mm for a given cadence , means you can get higher cadence rpm before spinning out.

The downside of shorter cranks is "It's harder to pedal uphill" (with the same gearing).

grasshopper
48 tooth chain ring SRAM 850  11 32 sprocket and  give me 20.6 to 111  gear inches.
 Way more range  than I need for Suffolk and Norfolk.

My gear range on the new recumbent is 17.5 inches to 108 inches. Originally I wondered if the bottom gear is too low / useable. The 9 speed crankset came off my retired mtn bike so was essentially free. I have used the low gear on a 20% hill and found it’s fine. Now I’m a bit stronger after five weeks on new recumbent I no longer need the bottom gear for 20%. At least when relatively fresh I don’t. The other end 108 gear inches gives me 29 mph at 90 rpm, so more than adequate for the flat and I tend to let the bike just freewheel on downhills.

175mm cranks as that what I have always run on the mtn bike the cranks were taken off.

Spend most of time in big or middle at front.  Middle chain ring up to about 10-12% gradient unless tired.
If you don’t make time for exercise now, sooner or later you’ll need to make time for ill health.
