Price difference

Interesting that the SRAM Rival 1 X-Horizon medium cage on the D31 copes with the upgrade from 36t to 42t. Or does it come supplied with the long cage?

I think the X1 only has one cage size - medium. Anyway I swapped out the stock 11-36 with a SRAM PG 1130 11-42 with no other changes. Derailleur worked perfectly, chain did not need to be lengthened. I didn’t even have to adjust the b screw. Cost was about 50 GBP. Seems like the bike should have been spec’d with this cassette, the range with this 1X is about the same as with 2 chainrings. SRAM Rival works flawlessly - my other bike has SRAM Red and I really cannot tell the difference. Rival is a bit heavier, but on an ebike a couple of hundred grams doesnt really matter.

The Rival deraileur and hydraulic brakes are a huge upgrade over the Shimano Altius.

While Altius is reliable basic derailluer, it definitely doesn't belong on a racing bike.

After a few comments about the gain being for experienced fit riders, i have been looking at mid drive bikes (eg cube acid) apart from being more capable on hills, what makes these type of bikes more suitable. I imagine they soak up the pot holes better but they are heavier to lift up steps and i would have thought harder to ride over 15 mph unless derestricted.

The GSM (Woosh kit) pedals up to 37 km/h no problem, over that I let gravity do it's thing. I have ridden without the battery, it is like a heavy normal bike. My cut off is set to 27 km/h on the LCD to compensate for the big tyres so 25 km/h on the GPS.

I think most of these comments are from emtb owners, so Here is my two peneth regarding my E-Road bike.. I have had the Giant Road e+1 for two years and it came with a compact 50/34 x 11-32 and have done nearly 3000 miles. I got a bit fed up with the double rings because changing between them creates an overlap so a smooth transition needs a double shift to maintain a similar cadence. In the end I converted to a single ring and is now 42 x 11-32 with the intention of going 11-36 or even 11-42 if the hills were a problem which they are not. I massivley prefer the single ring setup as I now have 11 sequential gears rather than 22 with a few overlaps, and it looks much better too.

I am going to put a 38 tooth on the upright when I install the Mxus, a good all round commuter gear for hilly towns. The freewheel is the DNP 11-32.

The trike with the GSM will also get a single chain wheel in the beginning so no way of riding all the way home in case of electric failure. 46:11-46 ratio covers just about every need. I have yet to spin out with the stock 48:11 top gear, in fact I've only been in top gear a couple of times since I've had it!

I don't have range anxiety.. the bike will easily do 60 miles (100km) even with my 70 year old legs and I don't go further than that.
