Nice start to the week with a warm Monday, had a lovely Dawn commute, finger tips were nipping in track mitts!, felt like Autumn today...
Home from work and i set about fitting the Shimano Alfine 8 speed Internal Gear Hub (IGH) to the Surly ECR...
The wheel i laced at the weekend, 193mm spokes for the Alfine hub to a Surly 29+ Rabbit Hole rim...
I find building the wheels very relaxing and satisfying...
I still have the other spare Rabbit hole rim to lace onto a Surly 100mm hub i just bought used on eBay,
This wheel will also go on the new progect, all revealed soon!,
Stripping the gears gives me a replacement 9 speed cassette,and chain which has less than 500 miles on it, along with the Microshift Thumb shifters, all this will be going on the old Pugsley soon...
White axle clamp washer sets the hub cable at the right angle...
Fitted the Surly Chain Tug with filed out hole to locate the Tab in the Alfine washer....
The Cheap Deore cranks previously fitted were taken off for the next project, and a square taper Shimano UN55 BB fitted, nice and cheap and will go for long enough on this bike...
And fitted the 170mm Middleburn RS7 cranks with Surly 32t stainless chain ring, these both are 7 years old now!...
Surly Monkey Nuts were removed from the chain stays to get the wheel right forward, possible now without a front mech. I could not get the rear calliper to slide forward enough, then remembered the Surly Troll 160mm calliper mount that came with the frame set...
Perfect...
KMC rustproof chain fitted and i could see the chain line not perfect, i could here it grinding when i cranked the bike!...
So crank removed i set the chain ring on the inside of the spider, also hid the spacers on the chain bolts, i need to get some single chain ring bolts...
Chain line better now and a lot quieter, looking good and perfect set up for my requirements of the ECR...
The days cloud bank that drifted inland from the coast here during the day and drifted back out to sea and the sun was back out burning nice and warm so i headed for a loop around Whitekirk using harvested fields where possible...
20t hub sprocket to 32 chain ring seemed ok this evening around here, you may want some higher and lower gears if you live near big hills...
I`m happy with the bike anyway!...
Sill for sale!...
No `stubble trouble` now in harvest fields or long grass, result!...
Dam it another Gorilla pod broke!!!, broke a dozon or so of these since i started blogging!...
Cloud bank rolling back in...
Got cooler as i rode for home. great wee loop, great bike, and listening to favourite tunes this evening on the ipod...
More soon...

ReplyDeleteCorrection on my previous reply it was 73 x 118, same as mentioned below by Tomi!
DeleteHi, my ECR has the RS7 cranks. They're mounted on a BB-UN55 73x118. Chainline is perfect for Alfine 8. The Chainring is a Middleburn "direct mount".
ReplyDeleteThank you! I bought 73x122.5 un55 and hope it will be ok with 1x11 and rear tire on biggest cassete ring :)
