I'm running a 54t pinion and a 104t spur. I'm out of space for increasing the size of the pinion gear.

The need for the smaller spur/larger pinion comes from the tires wearing down. I'm down to about 58mm.

Smaller spurs give more room to change FDR, 3.8-4.0 is usually what I run for 17.5 a 4.0 is a 4.0 no matter what size spur and pinion IMO

In your first post you said you are using xrays smallest 64p, but here you say you are using 104. Are you aware they go down to 92? PN XRA305862

I need some help. I'm trying to find a part number for the Xray progressive spring (not short spring) that would be the next hardest up from the progressive spring #308372 (2.2 - 2.6). I'm thinking it would probably be in the range of 2.6 to 3.0 ???
I've looked on the Xray website but all I can find is the 2.2 - 2.6 spring.
I'm beginning to think that they never released one.
Thanks.

Thanks for the reply. Just wondering if the progressive springs are laser etched any differently then the non progressive springs.
Thanks again.

The Xray progressives are laser etched with both numbers and (i think) a dash inbetween.

I don't recall any other 'long' springs apart from the 2.2-2.6
The newer short springs have 2.3-2.6 and 2.5-2.8

Default 13.5 gearing

17.5 is around 3.8 to 4.0! What would be good for 13.5 blinky?

Thank you! I was thinking a little higher from the 17.5 gearing. Sounds good!

Default Substitute front c hub bushings

I need one of those front c hub bushings, part #XRA302291, for this weekend. I can't get the part (without great expense) before the weekend. I was wondering if some one had any luck with some kind of temporary substitute? Maybe some brass or aluminum tubing from the hardware store and a washer/spacer? Maybe a part from another brand car?
I did a search about this, but found no entries.
